Dec 28 2022Hologres
Target customers: customers who use Flink and Hologres to build real-time data warehouses. Features released: Hologres binary logs can be consumed on source tables in the Java DataBase Connectivity (JDBC) mode. This mode supports more data types and allows you to create custom accounts. On the batch source tables and the full incremental source tables that are in the full phase, filter pushdown is supported. Data can be written to result tables in the fixed copy mode. This mode is supported in Hologres V1.3. Writes in the fixed copy mode can be achieved with higher throughput, lower delay, and less memory consumption, compared with those in the JDBC mode. In the fixed copy mode, data streaming is used. In the JDBC mode, data is processed in batches. Hologres Catalog: Default table properties can be set if you create catalogs.
