This topic lists the major features and bug fixes in Blink 3.4.4.

Major features

Blink 3.4.4 supports reading data from the new partitions of MaxCompute source tables. You can specify the subscribeNewPartition parameter in the DDL statement to enable or disable this feature. If the subscribeNewPartition parameter is set to true and the partition parameter is not specified, the system constantly reads data from the new partitions of MaxCompute source tables. For more information, see Create a full MaxCompute source table.

Major bug fixes

  • Fixes ApsaraDB for RDS connection issues. Blink uses the Druid database connection pool to connect to RDS. If the connection is not used for a long time, job failovers may occur. To avoid these issues, Blink 3.4.4 optimizes the method of connecting the Druid connection pool to RDS.
