Syed Shameerur Rahman updated FLINK-37329:
------------------------------------------
Description:
Currently when "table.optimizer.source.report-statistics-enabled" is set to
false, The statistics collection is not disabled for all the cases. It was
noted that when running Batch workload to read Hive table TPC-DS data set,
although "table.optimizer.source.report-statistics-enabled" was set to false,
both table and column statistics were being collected.
This goes against the configuration description :
{code:java}
@Documentation.TableOption(execMode = Documentation.ExecMode.BATCH_STREAMING)
public static final ConfigOption<Boolean>
TABLE_OPTIMIZER_SOURCE_REPORT_STATISTICS_ENABLED =
key("table.optimizer.source.report-statistics-enabled")
.booleanType()
.defaultValue(true)
.withDescription(
"When it is true, the optimizer will collect and use
the statistics from source connectors"
+ " if the source extends from
SupportsStatisticReport and the statistics from catalog is UNKNOWN."
+ "Default value is true."); {code}
