Behavioral Changes in Streaming Analytics

Review the list of Streaming Analytics behavioral changes in Cloudera DataFlow for Data Hub 7.2.15.

7.2.15.2

Summary:
Configurable checkpointing and failure restart strategy for SSB jobs.
Previous behavior:
Checkpointing and failure restart strategy followed the default Flink setting. This meant that both features were disabled by default and could not be configured using dedicated settings on Streaming SQL Console, only with SET statements for a specific job.
New behavior:
Both checkpointing and failure restart strategy features are enabled by default, and can be configured through Streaming SQL Console under the Settings panel of a SQL job.
Summary:
Materialized View exception handling
Previous behavior:
When an error occurred writing to the PostgreSQL database behind Materialized Views, the exception was caught and ignored, and did not affect the SQL job.
New behavior:
When an error occurs writing to the PostgreSQL database behind Materialized Views, the exception is logged, there is a retry attempt to allow jobs to recover before the job fails. When the job fails, the restart strategy and checkpointing settings are used.
