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.
