Can that cache in ‘review_site/cache’ be deleted？

[Z]

Hi,teams:

     That cache in review_site/cache are very large and slow to read on disk.

     After config the gerrit.config about cache,they can be deleted and how to rewrite autoly？

Thanks.

In general Gerrit uses caches to improve performance. This means flushing or deleting caches can have performance

impact until caches are re-populated.

You can delete persistent caches using init --delete-caches [1]. Note that some caches are expensive to recreate (e.g. diff caches).

Find details about Gerrit caches here [2]. In-memory cache content can be flushed using the gerrit flush-cache command [3].

Caches are automatically re-populated according to their configuration [2].

Thanks for reply.

Which caches  ‘In-memory’ and  ‘In-disk’  can be more helpful for gerrit?

And what is the standard of configuration for ‘In-memory’ and  ‘In-disk’  in gerrit.config？

Thank you very much.

You can monitor the cache hit rates using the ssh gerrit show-caches command [4] and monitoring [5]

and then tune them to your workload. You can also use the dashboards in [5] with an on-premise installation

of Prometheus and Grafana.

 

And what is the standard of configuration for ‘In-memory’ and  ‘In-disk’  in gerrit.config？

The defaults for each cache are documented in [2].
