👍 Highlights
Region Repartition RC.1 introduces Region Repartition, allowing users to dynamically adjust partition rules and redistribute data at runtime, without rebuilding tables or performing manual migrations.
- Split Partitions Split a large or hotspot partition into multiple smaller ones:
ALTER TABLE sensor_readings SPLIT PARTITION (
device_id < 100
) INTO (
device_id < 100 AND area < 'South',
device_id < 100 AND area >= 'South'
);
- Merge Partitions Merge multiple small partitions into a single one:
ALTER TABLE sensor_readings MERGE PARTITION (
device_id < 100 AND area < 'South',
device_id < 100 AND area >= 'South'
);
- Execution Control with WITH Clause
Users can control procedure behavior via
WITHoptions:
ALTER TABLE sensor_readings SPLIT PARTITION (
device_id < 100
) INTO (
device_id < 100 AND area < 'South',
device_id < 100 AND area >= 'South'
) WITH (
TIMEOUT = '5m',
WAIT = false
);
