compress_chunk() CommunityCommunity functions are available under Timescale Community Edition. Click to learn more.

The compress_chunk function is used to compress a specific chunk. This is most often used instead of the add_compression_policy function, when a user wants more control over the scheduling of compression. For most users, we suggest using the policy framework instead.

tip

You can get a list of chunks belonging to a hypertable using the show_chunks function.

Compress a single chunk.

SELECT compress_chunk('_timescaledb_internal._hyper_1_2_chunk');
