First; Is this the correct forum to ask questions about the Postgres Pro's new RUM-index? If not, please point me to the right forum. I think that https://github.com/postgrespro/rum/issues <https://github.com/postgrespro/rum/issues> might be the best forum.
Oleg and friends; Should we use GitHub-issues as forum (one issue per question/thread?), pgsql-general or something else? Andreas, we are hardly working on our internal version of rum and will open it after resolving some issues. I think the best place to discuss it is -hackers. Ah, as someone corrected me, we are working hard ! He he, I figured that was what you meant:-) Ok, so basically - will RUM-index support the same indexing-properties as GIN (being able to index tsvector, BIGINT-arrays, JSONB etc.) and be able to use index for sorting on ie. timestamp, tsrank or some BIGINT-column? Like my example, will it be possible to issue a query like this: SELECT del.id <http://del.id/> , del.sent FROM delivery del WHERE 1 = 1 AND del.fts_all @@to_tsquery('simple', 'hi:*') AND del.folder_id = ANY(ARRAY[2,3]:: BIGINT[]) ORDER BY del.sent DESC LIMIT 101 OFFSET 0; and have it use one RUM-index so the whole operation, including sorting, is as efficient as possible? we have implementation for timestamp. One need to write opclass to deal with arrays, it shouldn't be difficult. Will the opclass dealing with bigint-arrays also handle the single-element case, that is only one bigint? -- Andreas Joseph Krogh CTO / Partner - Visena AS Mobile: +47 909 56 963 andr...@visena.com <mailto:andr...@visena.com> www.visena.com <https://www.visena.com> <https://www.visena.com>
