What's New in Apache Kudu

Learn about the new features of Apache Kudu in Cloudera Runtime 7.2.11.

Add --newDatabaseName and --removeImpalaPrefix options to restore job

While Kudu does not have the notion of a database, users typically define full table names as <database>.<tablename>. Two new options are added to enable you to change the existing database name of a restored table or add a new database name to a restored table. The --newDatabaseName option enables you to specify a new database name for the restored table. The --removeImpalaPrefix option removes the impala:: prefix if it exists. The --newDatabaseName option does not affect the impala:: prefix.

Per-table size and row count limits

Kudu now experimentally supports per-table size limits based on leader disk space usage or number of rows. When generating new authorization tokens, Masters will now consider the size limits and strip tokens of INSERT and UPDATE privileges if either limit is reached. To enable this feature, set the --enable_table_write_limit master flag; adjust the --table_disk_size_limit and --table_row_count_limit flags as desired or use the kudu table set_limit tool to set limits per table.
