What's New in Apache Kudu
This topic lists new features for Apache Kudu in this release of Cloudera Runtime.
Table size metrics
Disk size and live row count of a table are exposed as metrics on the master server and on the master server's web UI. And the Kudu tablet's live row count is exposed on the tablet server's web UI, as well as metrics on the tablet server.
Capability to place tablet replicas based on dimensions
You can set dimensions when creating tables and adding partitions. This ensures that the new tablets are evenly distributed within the cluster based on dimension.
Support for adding and dropping range partitions using CLI
kudu table add_range_partition <master_addresses> <table_name> <lower_bound> <upper_bound> [-lower_bound_type] [-upper_bound_type] kudu table drop_range_partition <master_addresses> <table_name> <lower_bound> <upper_bound> [-lower_bound_type] [-upper_bound_type]
If you do not specify
upper_bound, then the
range partition is unbounded.
lower_bound_type and the
upper_bound_type parameters are
optional. The default values are
EXCLUSIVE_BOUND respectively. The parameters are case-sensitive.
