1.19.0 (Not released yet)

• #7181 StickyNotes feature
  • sticky notes are designed to store information inside scenario/fragment, they are separate from graph nodes and do not take part in scenario logic
  • new API available under processes/{scenarioName}/stickyNotes
  • configuration stickyNotesSettings allowing to hide/show stickyNotes, set sticky notes max content length or its max number on a graph
• #7145 Lift TypingResult information for dictionaries
• #7116 Improve missing Flink Kafka Source / Sink TypeInformation
• #7123 Fix deployments for scenarios with dict editors after model reload
• #7162 Component API enhancement: ability to access information about expression parts used in SpEL template
• async-http-client and Netty dependency cleanups
  • #7257 components-api module: Replaced wide dependency to async-http-client-backend-future by the narrowest possible dependency to sttp's core
  • #7259 flink-executor and lite-runtime modules: Added compile-time dependency to http-utils (which depends on async-http-client-backend-future and indirectly on Netty)
• #7066 Kafka source and sink can now operate with schemaless topics. They accept any json. Data will not be validated with schema.
• #7165 Added PerformSingleExecution scenario action
  • Added support for PerformSingleExecution action in DeploymentManager and in GUI
  • Improved scenario state management to include information about current and deployed versions and allow more customization
• #7184 Improve Nu Designer API notifications endpoint, to include events related to currently displayed scenario
• #7323 Improve Periodic DeploymentManager db queries
• #7332 Handle scenario names with spaces when performing migration tests, they were ignored
• #7346 OpenAPI enricher: ability to configure common secret for any security scheme
• #7307 Added StddevPop, StddevSamp, VarPop and VarSamp aggregators
• #7341 Added possibility to choose presets and define lists for Integer typed parameter inputs in fragments.
• #7356 Integers converted to BigDecimals have scale 18, this fixes issue with unexpected low scale when performing division on BigDecimals which were created in such conversion.
• #7379 Removed CustomAction mechanism.
• Changes to periodic component (renamed to event-generator):
  • #7502 Component rename: periodic to event-generator
  • #7502 Parameter rename: period to schedule
  • #7373 Improvements to schedule editor
  • #7376 Previously, when count was > 1, the value was evaluated once and emitted times count. For example: if the value was evaluated to be a random UUID and count was 5, one UUID was generated and emitted 5 times. Now in one count batch each value is evaluated separately.
• #7386 Improve Periodic DeploymentManager db queries, continuation of #7323
• #7360 Added Median aggregator

• #7354 Reduce response payload size when fetching scenarios for scenarios tab by removing unused fields and null attributes.
• #7404 Fix SpEL evaluation error when using conversion extensions methods or array.get extension method
• #7420 Add toInteger and toIntegerOrNull conversions. Also add canBeInteger extension
• #7438 Map int32 integer format in OpenAPI schema to the Integer type
• #7446 Small changes regarding node errors in fragments used in scenarios:
  • Fragment error node tips in scenarios are now clickable and open problematic node edit window in a new tab.
  • Fragment nodes are now highlighted when they contain nodes with errors.
• #7364 PeriodicDeploymentManger is no longer a separate DM, but instead is an optional functionality and decorator for all DMs
  • in order to use it, DM must implement interface schedulingSupported, that handles deployments on a specific engine
  • implementation provided for Flink DM
• #7443 Indexing on record is more similar to indexing on map. The change lets us access record values dynamically. For example now spel expression "{a: 5, b: 10}[#input.field]" compiles and has type "Integer" inferred from types of values of the record. This lets us access record value based on user input, for instance if user passes "{"field": "b"}" to scenario we will get value "10", whereas input {"field": "c"} would result in "null". Expression "{a: 5}["b"]" still does not compile because it is known at compile time that record does not have property "b".
• #7324 Fix: Passing Flink Job Global Params
• #7335 introduced managersDirs config to configure deployment managers directory paths (you can use MANAGERS_DIR env in case of docker-based deployments). The default is ./managers.
• #7481 Ignore jobs in CANCELLING status when checking for duplicate jobs on Flink
• #7483 It's possible to configure kafka source to work without schema registry. To do that you should not provide property "schema.registry.url" in kafkaProperties config.
• #7458 Flink scenario testing mechanism and scenario state verification mechanism: mini cluster created once and reused each time
• #7498 Support many migrations loaded using SPI. Loaded migration numbers cannot overlap, if they do, an exception is thrown.
• #7504 Return scenario validation error when an incompatible change was introduced in a fragment or component parameter definition.
• #7468 Configurable namespace separator (was fixed to _), added namespace tag to Lite engine metrics and fixed namespacing of Kafka consumer groups.
• #7508 Fixes for window components:
  • Can now pass more than 31 days as windowLength and it won't be reduced to remainder of 31
  • Introduced some default values:
    • For all - default windowLength is 1 hour
    • For aggregate-session - default endSessionCondition is now false
• Improved scenario visualization loading time
  • #7516 Scenario testing endpoints no longer perform full scenario compilation and validation

Highlights

End-user

• Flink Catalogs integration. Thanks to Catalogs, Nu can be used to act on data stored in Data Lakehouses.
• Improvements in batch mode, including joins, testing (dry runs) and general usability.

  • Combine statuses Failing, Failed, Error, Warning, FailedToGet and MulipleJobsRunning into one status that represents a "Problem". Statuses FailedStateStatus and "Unknown" are removed.
  • Status configuration for icon, tooltip and description is obligatory.
• #4100, #4104, #4150 Before the change, the scenario list for a moment presented "local" states - based only on Nussknacker's actions log. After the change, we always present state is based on engine (e.g. Flink) state - in some places like scenario list, it is cached.

1.5

1.5.0 (16 Aug 2022)
