Is there a way to do this by invoking the parser on a query/SQL statement instead of doing it manually? Might be easier to adapt in the future if we'd want to, e.g., invoke compress chunks on multiple chunks in a single statement. Something like:
SELECT compress_chunk(ch)
FROM show_chunks(hypertable) ch LIMIT 10;

I'll do the research and get back to you.

A question here, how would this work with 2PC? Meaning, this query would generate 10 2PC transactions, correct? Would those transactions happen concurrently? Is the concurrency limited by max_prepared_transactions?

I've temporarily added a policy_invoke_compress_chunks() function in addition to the policy_invoke_compress_chunk() function.
I replaced it at the access node level to see how it compares. If we are talking about doing that at the data node level then for sure it is too much work for this PR and would need to discuss it.
We usually do not refer to private issues from public issues. It might be better to create a public issue for this and refer to it. |

This release adds major new features since the 2.2.1 release. We deem it moderate priority for upgrading. This release adds support for inserting data into compressed chunks and improves performance when inserting data into distributed hypertables. It also adds support for triggers and compression policies on distributed hypertables. The bug fixes in this release addresses issues related to the handling of privileges on compressed hypertables, locking, and triggers with transition tables. **Features** * timescale#3116 Add distributed hypertable compression policies * timescale#3162 Use COPY when executing distributed INSERTs * timescale#3199 Add GENERATED column support on distributed hypertables * timescale#3210 Add trigger support on distributed hypertables * timescale#3230 Support for inserts into compressed chunks **Bugfixes** * timescale#3209 Propagate grants to compressed hypertables * timescale#3229 Use correct lock mode when updating chunk * timescale#3241 Fix assertion failure in decompress_chunk_plan_create * timescale#3243 Fix assertion failure in decompress_chunk_plan_create * timescale#3250 Fix constraint triggers on hypertables * timescale#3251 Fix segmentation fault due to incorrect call to chunk_scan_internal * timescale#3252 Fix blocking triggers with transition tables **Thanks** * @yyjdelete for reporting a crash with decompress_chunk and identifying the bug in the code
