Subject [jira] [Commented] (SOLR-5750) Backup/Restore API for SolrCloud
Date Mon, 02 May 2016 04:17:13 GMT


David Smiley commented on SOLR-5750:

I made some small updates to the branch like I said I would. I elected _not_ to switch Snapshooter
to use mkdir instead of mkdirs for back-compat concerns so I have the backup caller make this
check instead.

[~hgadre] I took a look.  As this issue finally nears the end, I don't feel good about rushing
into the multiple abstractions introduced in the P/R (not to say I don't like them).  Please
file a new issue and add me as a Watcher.  I have some comments but I'll wait to put them

> We should have an easy way to do backups and restores in SolrCloud. The ReplicationHandler
supports a backup command which can create snapshots of the index but that is too little.
> The command should be able to backup:
> # Snapshots of all indexes or indexes from the leader or the shards
> # Config set
> # Cluster state
> # Cluster properties
> # Aliases
> # Overseer work queue?
> A restore should be able to completely restore the cloud i.e. no manual steps required
other than bringing nodes back up or setting up a new cloud cluster.
> SOLR-5340 will be a part of this issue.
