= gerrit flush-caches
== NAME
gerrit flush-caches - Flush some/all server caches from memory.
== SYNOPSIS
[verse]
--
_ssh_ -p <port> <host> _gerrit flush-caches_ --all
_ssh_ -p <port> <host> _gerrit flush-caches_ --list
_ssh_ -p <port> <host> _gerrit flush-caches_ --cache <NAME> ...
--
== DESCRIPTION
Clear an in-memory cache, forcing Gerrit to reconsult the ground
truth when it needs the information again.
Flushing a cache may be necessary if an administrator modifies
database records directly in the database, rather than going through
the Gerrit web interface.
If no options are supplied, defaults to `--all`.
== ACCESS
The caller must be a member of a group that is granted one of the
following capabilities:
* link:access-control.html#capability_flushCaches[Flush Caches] (any cache
except "web_sessions")
* link:access-control.html#capability_maintainServer[Maintain Server] (any cache
including "web_sessions")
* link:access-control.html#capability_administrateServer[Administrate Server]
(any cache including "web_sessions")
== SCRIPTING
This command is intended to be used in scripts.
== OPTIONS
--all::
Flush all known caches. This is like applying a big hammer,
it will force everything out, potentially more than was
necessary for the change made. This option automatically
skips flushing potentially dangerous caches such as
"web_sessions". To flush one of these caches, the caller
must specifically name them on the command line, e.g. pass
`--cache web_sessions`.
--list::
Show a list of the caches.
--cache <NAME>::
Flush only the cache called <NAME>. May be supplied more
than once to flush multiple caches in a single command
execution.
== EXAMPLES
List caches available for flushing:
----
$ ssh -p 29418 review.example.com gerrit flush-caches --list
accounts
diff
groups
ldap_groups
openid
projects
sshkeys
web_sessions
----
Flush all caches known to the server, forcing them to recompute:
----
$ ssh -p 29418 review.example.com gerrit flush-caches --all
----
or
----
$ ssh -p 29418 review.example.com gerrit flush-caches
----
Flush only the "sshkeys" cache, after manually editing an SSH key
for a user:
----
$ ssh -p 29418 review.example.com gerrit flush-caches --cache sshkeys
----
Flush "web_sessions", forcing all users to sign-in again:
----
$ ssh -p 29418 review.example.com gerrit flush-caches --cache web_sessions
----
