If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

If this boolean column is true, a relations is Incrementally Maintainable
Materialized View (IMMV). This is set when IMMV is created.

Also, isimmv columns is added to pg_matviews system view.

* [PATCH v4] Provide relfilenode statistics
@ 2023-11-16 02:30  Bertrand Drouvot <[email protected]>
  0 siblings, 0 replies; 81+ messages in thread

From: Bertrand Drouvot @ 2023-11-16 02:30 UTC (permalink / raw)

We currently don’t have writes counters for relations.
The reason is that we don’t have the relation OID when writing buffers out.
Tracking writes per relfilenode would allow us to track/consolidate writes per
relation.

relfilenode stats is also beneficial for the "Split index and table statistics
into different types of stats" work in progress: it would allow us to avoid
additional branches in some situations.

=== Remarks ===

This is a POC patch. There is still work to do: there is more places we should
add relfilenode counters, create more APIS to retrieve the relfilenode stats,
the patch takes care of rewrite generated by TRUNCATE but there is more to
care about like CLUSTER,VACUUM FULL.

The new logic to retrieve stats in pg_statio_all_tables has been implemented
only for the new blocks_written stat (we'd need to do the same for the existing
buffer read / buffer hit if we agree on the approach implemented here).

The goal of this patch is to start the discussion and agree on the design before
moving forward.
