Hello people, I have a doubt to ask. In the current setup we use redis 'for sessions and to cache requests to external APIs' like wikimedia. At the same time, it’s a popular practice to use a Redis caching layer to your Elasticsearch queries. Any specific reason not to do so ?

Hi MohamedAli00949 (IRC) did you modify stylesheets/style.scss ? The error says it found an unexpected question mark somewhere, but I can't replicate the issue myself.

monkey, by storing the results of database queries and checking for them before having to search again, in my view this could be achieved. Isn't it?
2024-03-07 06717, 2024
insane_22
Saw after googling that it's used at places and wanted to validate if it would even be needed in our case
2024-03-07 06726, 2024
insane_22
actually, I was looking into project musicbrainz search server wherein they use solr search to have a better idea of the way things are done. It uses "RabbitMQ which gathers data to be indexed from the database, and finally builds searchable documents and sends these to the Solr search server". I was thinking about using Redis for the same and
2024-03-07 06726, 2024
insane_22
other ways by which we can improve upon things.

Nope, just me switching between computers :)
2024-03-07 06711, 2024

IMO using rabbitMQ is the way to go
2024-03-07 06723, 2024
monkey[m]
Regardless of caching query results
2024-03-07 06704, 2024
monkey[m]
Also I think a good start would be tuning the debounce for the search inputs, currently it's too low and we're doing a bunch of searches as we type
2024-03-07 06754, 2024
monkey[m]
If you want to fix that too it's an easy one with good resource savings
2024-03-07 06727, 2024
monkey[m]
I'd have to read up on using redis for caching query results: got some docs I can read ?
2024-03-07 06759, 2024

We are actually thinking of using PostgreSQL directly for search indexing in MusicBrainz.
2024-03-07 06725, 2024
yvanzo
It seems to be manageable without RabbitMQ.
2024-03-07 06720, 2024
yvanzo
At least it is for indexing cover art.
2024-03-07 06741, 2024

This is an implementation details and it probably doesn’t matter much at BB scale.

Also MB search results are cached through OpenResty which uses nginx.

Thank you yvanzo for your replies
2024-03-07 06704, 2024

with rabbitMQ I'm a bit familiar but have no idea of use cases, implementation or anything of OpenResty.
2024-03-07 06722, 2024
insane_22
also I would like to know if there are any reasons not to use redis?
It seems feasible to use Redis/KeyDB as message broker.
2024-03-07 06754, 2024

I would still advise to start with the simplest solution (PG table) at first, and have metrics through Prometheus to monitor scalability.

interestingly, for musicbrainz, all of the message data that sir needs is already stored in postgres (under dbmirror2.pending_data). so we have triggers pushing the same data to rabbitmq for no real reason

(For others, dbmirror2 is more recent than the search architecture.)

I would concur with the use of a PG table though. postgres is very capable for messaging nowadays if you don't need advanced routing
2024-03-07 06722, 2024
bitmap
and it's one less service to manage
2024-03-07 06730, 2024
yvanzo
Also avoiding the need of a bridge PG-RabbitMQ or PG-Redis makes it much simpler to maintain.
2024-03-07 06735, 2024

you can safely have multiple consumers take items from the table with `SELECT ... FOR UPDATE SKIP LOCKED`

imo, all of us are on the same page about this:- using postgres directly for sending trigger messages to search index rebuilder

In Musicbrainz as told by yvanzo it's done "through OpenResty which uses nginx", I had earlier thought of using redis to do this
