What's New

Service Module

Major Changes

Doris

  • Doris clusters can be created. Doris is a real-time analytical database that is easy to use and has high performance. It needs to be deployed independently.
  • SQL inspector blocks and intercepts large and slow SQL statements in Doris based on preset and custom inspection policies.
  • Doris slow query detection is added, improving the O&M monitoring capability of Doris.

Flink

FlinkSQL supports the MultiJoin operator.

Hadoop

  • The HDFS asynchronous deletion feature is used to delete large directories. Deleting blocks asynchronously with traffic control can effectively shorten the continuous lock period.
  • YARN can detect large tasks to prevent the disks from being used up.

HBase

Spark BulkLoad can quickly synchronize Hive or Spark table data to HBase tables and import full or incremental table data in ORC/PARQUET format.

HetuEngine

HetuEngine supports Oracle and GBase data sources.

Hive

  • The Hive component of a normal cluster supports cascading authorization.
  • Hive can intercept SQL statements that read and write data by themselves.

Hudi

The Hudi kernel is upgraded to 0.15.0.

JobGateway

The new component JobGateway is added to submit REST API jobs.

Manager

Now Keytab files can be downloaded to a remote node.

Precautions

None.
