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.
