Adopting Graph Scripting QSL
As of versions 2.7.18 and 2.8.2, Graph Scripting QSL is the new, generally available standard for batch-based Network Generation, replacing the now-deprecated Graph Scripting DSL. The benefits of migrating to QSL are significant, including major performance gains, simplified low-code development, and alignment with the future direction of the Quantexa Platform. For a full overview of these benefits, please see our introductory article: Introducing Graph Scripting QSL: Faster, Smarter Graph generation capabilities. This article is the practical follow-up, designed to help Technical Leads and Developers plan and execute the migration from DSL to QSL. When to Plan Your QSL Migration With DSL now deprecated, all projects using it must plan for a migration. The timing of this migration depends on your project's current state: Project Status Recommendation New Projects All new projects starting on platform version 2.7.18+ or 2.8.2+ should use QSL by default. Existing Deployments (pre-v2.7) The migration from DSL to QSL should be planned as a key activity within your v2.7 (or later) upgrade project. Existing Deployments (on v2.7+) The QSL migration can be prioritized and executed as a standalone project, independent of a major platform upgrade. Migration Approach and Effort Planning The official DSL to QSL migration process involves setting up a new, clean QSL configuration and then re-implementing your existing DSL expansion logic using the new path-based syntax. This is not an automated, in-place conversion. When planning for this effort, use the following as a baseline estimate: Core Implementation: On average, projects require ~6 days of effort to perform the initial QSL setup and re-implement 1-3 expansion graphs, including initial development testing. Additional Expansions: The effort does not scale linearly. Budget an additional 0.5-1 day of effort for each additional expansion path you need to migrate. Formal Testing: Budget an additional 5 days for a full regression testing cycle. This allows time to thoroughly validate the graph outputs and investigate any differences. Historically, reported differences have typically been the result of rectifying undesirable DSL behavior rather than issues with QSL itself. Key Considerations During Migration As you plan your migration, be aware of these key technical differences between DSL and QSL: Single Scoring Graph: QSL generates a single ScoringGraph. If your multi-use-case setup relies on different graphs for different use cases, you may need to configure multiple, independent graph-scripting modules. Path-Based Expansions: QSL's path-based expansions are more precise than DSL's perimeter-based approach. For very complex DSL graphs, this may require you to define your logic as a larger number of more specific QSL paths. Attribute Availability: Attributes not explicitly used in an expansion are not automatically carried through to scoring traversals. Review the migration notes on attributes to ensure your scoring logic has access to the data it needs.
2.9 Quantexa Upgrade Guide
Table of Contents Quick Upgrade Overview Community Upgrade Guidance Dependencies and Platform Modernisation User Interface Changes Pre-built Images and Pre-packaged Artifacts Backend and Data Pipeline Changes Data Packs Migration Recent Deprecations Software Compatibility Additional Information Quick Upgrade Overview The 2.9 Quantexa Upgrade consists of five main parts: Dependencies and Platform Modernisation User Interface (UI) Changes Pre-built Images and Pre-packaged Artifacts Backend and Data Pipeline Changes Data Packs Migration The 2.9 release is one of the most structurally significant Quantexa upgrades to date. The headline change is the move to pre-built Docker images for App Tier applications. Rather than compiling application modules project-side, projects now use the Image builder plugin to layer project-specific extensions onto Quantexa-provided base images. This fundamentally changes the build and deployment model and drives many of the API refactoring changes across the platform. On the dependencies side, this release involves major framework upgrades: Gradle 9, Spring Boot 4, Node.js 24, and Angular 21. Elasticsearch 7 and OpenSearch 1, deprecated in 2.8, have been fully removed - projects must be on Elasticsearch 8/9 or OpenSearch 2. Elasticsearch 9 is newly supported. While the Repository Tool handles most of the automated migration, projects with custom Gradle build code, custom Spring configuration, or custom UI code should budget additional manual effort. The User Interface tier includes many configuration restructuring changes. Global UI configuration, Explorer dynamic configuration, and Search 2 configuration all move to versioned directory-based formats. The Home Page reaches General Availability (GA), several Investigation modules are removed, and PrimeNG is replaced with a Quantexa-maintained fork. Data Packs 2.3.x remain compatible with Quantexa 2.9 and require Parsers 4.2.3 or later. This page provides additional guidance for the 2.9 Quantexa Upgrade. For the full list of required migration steps, please refer to the Documentation site migration guide: 2.8 → 2.9 Upgrade Migration Guide. Release Notes: Community Release Announcement 2.9 Release Notes Community Upgrade Guidance Dependencies and Platform Modernisation Gradle 9 Upgrade This is one of the most impactful changes in the 2.9 upgrade. Gradle 9 removes several build script APIs and tightens behavioural rules that previously generated only deprecation warnings. The Repository Tool automates the migration for patterns used in Quantexa-generated build files, covering changes such as replacing configurations.all with configurations.configureEach, updating archivesBaseName to archiveBaseName.set(), and reordering sourceSets blocks. However, deployments with custom Gradle build code will almost certainly require additional manual changes. After the automated migration, run ./gradlew build and resolve any remaining failures. Common follow-up tasks include replacing usage of removed org.gradle.util.CollectionUtils methods and reviewing any include directives that the migration commented out in settings.gradle. Spring Boot 4 Upgrade The mid-tier has been upgraded from Spring Boot 3.x to Spring Boot 4.0, introducing breaking changes for all deployments. A Scalafix rule handles Scala source file migrations, and a Plop migration covers common changes such as relocating configuration keys (server.error → spring.web.error) and updating Spring Boot imports. However, the Plop migration cannot cover every Spring Boot 4 scenarios, especially for custom code. After running the automated migrations, manually review the official Spring Boot 4.0 Migration Guide for any additional changes your deployment requires. Note that moving to pre-built images also eliminates many Spring bean extension points, replacing them with Scala singleton objects (see Pre-built Images section below). Elasticsearch 7 and OpenSearch 1 Removed Following their deprecation in 2.8, Elasticsearch 7 and OpenSearch 1 have been fully removed. Deployments still on ES7 must upgrade to Elasticsearch 8 or 9 before upgrading to 2.9. Deployments on OpenSearch 1 must upgrade to OpenSearch 2. Elasticsearch 9 is now supported alongside Elasticsearch 8. Quantexa recommends upgrading to ES9 for the latest performance and security improvements. However, note the following limitations in 2.9.0: EmbeddedElasticServer is not supported for ES9 - deployments using it for local testing must migrate to Docker-based Elasticsearch Offline Indexing is currently not supported with ES9 OpenSearch 3 is not supported in this release The elastic*-builder NPM packages used by the UI for ES7 query building have also been removed. Node.js 24 and Angular 21 Node.js has been updated from version 22 to 24 (required by Angular 21). Angular has been updated to version 21. Plop automatically handles the UI code migration. As with the 2.8 Angular upgrade, Plop may fail to migrate package-lock.json to a consistent state - if you encounter UI build errors, delete node_modules and package-lock.json from the web-app folder and run npm install to regenerate them. Ensure all CI/CD pipelines, development environments, and Docker build stages reference the new Node.js version. User Interface Changes Home Page (General Availability) The Home Page reaches General Availability in 2.9, providing a configurable landing page with widgets for quick access to recent activity, tasks, and investigations. A Plop migration is available for initial setup. Projects should review their Home Page configuration and test the landing experience post-migration. Investigation Modules Removed The Investigation modules deprecated in 2.8 (replaced by Resource Viewer) have been fully removed. The affected modules include CompoundGraphViewModule, SourceViewerPluginModule, RecordViewerPluginModule, and others. A Plop migration handles the removal. Projects should have already migrated to Resource Viewer during the 2.8 upgrade. Additionally, the Custom Bulk Search component has been removed - Bulk Search configuration is now fully managed through the standard configuration approach. Global UI Configuration Migrated to Versioned HOCON The Global UI configuration has been restructured from a monolithic JSON file to a versioned directory containing HOCON configuration and a version.conf file declaring the schema version. This enables automatic schema migration during platform upgrades. Plop creates a config/global-ui/ directory structure and updates application.yml paths. Several previously unused fields (validFrom, validTo) have also been removed. Projects must verify that deployment manifests (Helm Chart or QAT) are updated to mount the new directory as a ConfigMap volume. Explorer and Search 2 Configuration Split Explorer dynamic configuration has been split from a single monolithic file into per-schema .conf files within an explorer-dynamic-configuration/ directory, with an index.conf file. Search 2 configuration follows the same versioned directory pattern, migrating from a single JSON file to config/search2/ containing search2-dynamic-config.conf and version.conf. Both Plop migrations handle the conversion, update application.yml paths, and add ConfigMap entries to deployment scripts. Projects must verify that the updated volume mounts are present in their deployment manifests. PrimeNG Fork and Dependency Cleanup PrimeNG has been replaced with @quantexa/primeng-fork, a Quantexa-maintained fork. All primeng/* imports in TypeScript, CSS, and SCSS files must be updated - a Plop migration handles this automatically. Additionally, Web Core peer dependencies have been removed from project-level package.json and are now managed by the @quantexa/web-core package. After migration, regenerate package-lock.json by deleting node_modules and the lock file, then running npm install. To keep dependency overrides up to date between major releases, use the src:cve-update script. The project-level ESLint configuration and its dependencies have also been removed. Projects that require ESLint must configure it independently. UI script and import paths have been updated: the lint, src:migrate-scss, and eslint-config:link scripts are removed, and @quantexa/script-lib imports must be updated to @quantexa/utils and @quantexa/build-tools. Alternative Network Layouts (General Availability) Alternative Network Layouts, which provide different ways to visualise entity networks, reach General Availability in 2.9. A Plop migration renames edge configuration properties. Projects using custom network layout configuration should review the updated property names. Localisation Configuration Restructured The localisation configuration has been restructured for multi-language support. This is a breaking change with Plop migration support. Projects should verify their localisation setup post-migration. Low-Code Configuration (LCC) Validation Tests LCC validation tests have been migrated to a new location. A Plop migration updates test locations and imports. Continue to run configuration validation tests early in the upgrade process to catch configuration errors before deployment. Pre-built Images and Pre-packaged Artifacts Application Pre-built Docker Images This is the most architecturally significant change in 2.9. Applications are no longer compiled project-side. Instead, Quantexa provides pre-built Docker images for App Tier services (all applications except the UI and app-fusion). Projects use the Image builder plugin to layer project-specific extensions onto these base images. The migration involves seven steps, which must be completed in order: Migrate application extensions to dedicated modules (Manual) - custom code in application modules (e.g. app-security/src/main/, app-investigate/src/main/) must be moved to dedicated extension modules with recognized naming conventions that the Image builder plugin auto-discovers. Register Foreign Documents for Fusion data configuration (Manual) - applications now read data configuration from fusion-data-config.json rather than compiled Scala models. Foreign Documents not automatically included must be registered via .qdocuments and .qmodel files. Migrate SAML metadata files (Plop) - the classpath: protocol for SAML metadata is no longer supported; XML files must be moved from app-security/src/main/resources/ to a mounted config/saml/ directory. Migrate optional modules to feature flags (Plop) - optional service dependencies in build files are replaced with feature flags in deployment configuration. Add Image builder plugin configuration (Plop) - adds the plugin to the root build and creates the applications.gradle file. Migrate each application to pre-built images (Plop) - replaces each application module with a .gitkeep, updates settings/libraries/applications Gradle files. Update deployment configuration (Manual) - applications with project-specific extensions are renamed with a -project suffix (e.g. app-resolve becomes app-resolve-project). Deployment configuration must reference the new names. This migration has a cascading impact across the platform. Many of the API changes in Visualization and Exploration (see below) are directly driven by this change - extension points that previously relied on Spring bean registration in compiled application modules must now use Scala singleton objects in dedicated extension modules. Projects should follow the Application Pre-built Image Migration Guide carefully. For projects that need help adopting container-based deployment, speak to your Quantexa Architect. They can help assess your current deployment model and plan the transition to pre-built images. Impact on Local Development The move to pre-built Docker images changes the local development workflow. Previously, developers could run mid-tier applications locally using bootRun or java -jar commands. With pre-built images, these applications are no longer compiled project-side, so the traditional local run scripts no longer apply for most App Tier services (the UI and app-fusion are still built project-side). There are three options for development workflows going forward: Cloud-based or development environment development (recommended) - develop against a shared or personal Kubernetes development namespace with CI/CD pipelines configured for rapid iteration. This is the approach Quantexa uses internally and is the recommended path. Projects should work with their Quantexa Architect to set up development namespaces that support concurrent developer activity, including sizing the environment to handle multiple developers working in parallel. Local container-based development - use Minikube, Docker Desktop, or an equivalent local Kubernetes environment to run pre-built images on a developer laptop. This preserves the ability to work locally but requires container tooling to be available on the development machine. The overhead of Docker itself is relatively low, but the growing footprint of the full application stack may be challenging on lower-specification machines. Projects should verify that laptop or VDI specifications are sufficient for this approach. Pre-built boot JARs (fallback) - pre-built Spring Boot JARs are available for projects that cannot adopt container-based development locally. However, this means local development uses a different deployment pattern to higher environments, requiring the project to maintain two deployment approaches and accept the risk of environment divergence. The same structural migration steps (dedicated extension modules, Image builder plugin configuration) still apply to ensure compatibility with repository migrations in later Quantexa versions. Projects upgrading to 2.9 should factor the development workflow transition into their migration effort estimates. For environments with strict change management requirements where cloud-based development namespaces are not readily available, discuss options with your Quantexa Architect early in the upgrade planning process. Pre-packaged Batch Shadow JARs Quantexa now provides pre-packaged shadow JARs for Batch tier tasks, eliminating the need to compile batch platform code from source. A Plop migration updates project structure and build configuration. Projects with custom batch tasks should review the migration to ensure their custom tasks integrate correctly. Backend and Data Pipeline Changes Data Fusion and ETL Several changes affect the Data Fusion and ETL pipeline: ENGFull renamed to BatchFull (Plop) - generated ETL script classes have been renamed from ENGFull{Model}ETLScript to BatchFull{Model}ETLScript. Template files have similarly changed from runAllENG.sh to runAllBatch.sh. Metadata excluded from hash ID calculation (Plop) - the metaData field is now excluded from hash ID computation by default when using hashIdField configuration. This improves Entity Resolution (ER) stability during incremental ETL runs. To preserve the previous behaviour, add metaData to the including list in your hash ID configuration. fusion-spark-utils removed - projects using this library must migrate to the replacement APIs. Document type validation against Fusion config (Manual) - document type definitions in Resolver configuration are now validated against Fusion configuration at startup. If a Document type is defined in Resolver but missing from the corresponding .qdocuments file, the application will fail to start with an IllegalStateException. Resolver and Batch Resolver Several Resolver APIs have been cleaned up: liftAttributes removed (Manual) - the liftAttributes configuration option has been removed without replacement. This changes how Record Attributes with mixed types are handled across Document types. Projects should check Batch Resolver logs for Record attributes to lift: entries to identify impact. Path methods removed (Manual) - several Path convenience methods have been removed from the Batch Resolver API. Resolver configuration cleanup (Plop) - several deprecated fields have been removed: dataModelRootClass, dataModelRecordExtractor, intelligenceModelClass, intelligenceModelExtractor from document/intelligence definitions; icon from entity definitions; availableIcons from UDI document definitions. Entity Store Key changes to the Entity Store: Custom External Attributes (Manual) - must now be defined in a dedicated custom-external-attributes module and configured via the external-attributes.calculations-object property. Previously, these could be defined in any module and injected as a Spring Bean. Custom Attribute Functions: ValidatedNel → Either (Manual) - the return type has changed from ValidatedNel to Either[List[String], T], and the expectedFields and name variables have been removed from the relevant traits. Custom Data Quality Functions (Manual) - the EntityQualityCheckAggregation interface now requires usedEntityAttributes and usedRecordAttributes properties. Error handling changes (Manual) - the Entity Store REST API now returns clearer error responses (validation errors return 400, timeouts return 503). Deployments with custom error handling logic must update their implementation. Change Log metadataPath (Plop) - Entity Store Change Log, CRUD Log, Document Log, and Batch ETL to Stream scripts now require a metadataPath configuration property. Scoring The elastic*-builder Gradle dependency has been removed. The Scoring Dynamic subproject requires migration to a new structure; follow the Scoring Dynamic Subproject Migration Guide. Both have Plop support, but deployments with custom Scoring configuration should review changes carefully. Data Integration Several Data Integration changes: Kafka Ingest error handling configuration (Manual) - error handling configuration has been refactored as part of the pre-built image migration, moving to a dedicated extension module. RecordExtractionModelConfig refactored (Manual)-RecordExtractionModelConfig has been replaced by RecordExtractionModelConfigBuilder. Search Related Entities configuration (Manual) - configuration has been updated as part of the pre-built image migration. Combined Ingest service removed - the combined ingest service has been fully removed. DatasourceTestSpec deprecated - DatasourceTestSpec is deprecated in favour of ETLTestSpec. Additionally, Elasticsearch-backed data source integration tests (GenericFullEtlRun ES variants) have been removed. Q AI - Q Assist Q Assist Workspace Agents reach Public Preview in 2.9. LLM configuration for Q Assist has been updated - projects using Q Assist must review and update their LLM provider configuration. This is a manual change. Decision Systems Decision Systems 2.9.0 includes breaking changes. Key changes include: initialTaskGraph is now required, Hub and Spoke Scores have been removed, and Contextual Data Mapping has been converted to Monitored Data. See the 2.8 → 2.9 Decision Systems Migration Guide for step-by-step guidance. Data Packs Migration Data Packs 2.3.x are compatible with Quantexa 2.9.x and require Parsers 4.2.3+, 4.3.x, or 4.4.x. Parsers 3 has not been supported since Quantexa 2.8. If your project has not yet completed the Parsers 4 migration, complete it before upgrading. For planning and step-by-step guidance, see: Why & How to Plan a Parsers 4 Migration Step-by-step Guide to Migrate to Parsers 4.3 There are no Data Packs-specific breaking changes in the 2.9 upgrade beyond what is covered by the platform migration. Projects already on Data Packs 2.3.x with Parsers 4 can continue using the same version. For the full Data Packs compatibility matrix, see Data Packs Compatibility Matrix. Recent Deprecations PyQSS Import Path The PyQSS import path has been deprecated. Projects using PyQSS should update their imports to the new path. I/O Handler Environment Variables I/O handler environment variables have been deprecated in favour of updated configuration. smart_open Library The smart_open library has been deprecated. icon Property in Resolver and Fusion Document Definitions The icon property in Resolver and Fusion Document definitions is deprecated. While the property still functions, it will be removed in a future release. DistinctValue for List Type Fields Using DistinctValue for List type fields is deprecated. DatasourceTestSpec The DatasourceTestSpec class is deprecated in favour of ETLTestSpec. Bundled libpostal Bundled libpostal in app-kafka-record-extraction and app-search-related-entities images is deprecated. Projects relying on the bundled version should plan to provide their own libpostal installation. transliterateElements The transliterateElements configuration has been deprecated.
