Varun Thacker commented on SOLR-7374:
-------------------------------------
Hi Hrishikesh,
bq. So in case there are multiple repositories configured, we need a way to
configure which repository to use
Alternatively how do you feel about forcing a default repository if multiple
repos are configured? Currently if there is just 1 we make that default but
when there are multiple repositories we don't necessarily need to provide a
default.
Mark - Sure I can assign it to myself. I'd like your opinion and Hrishikesh's
opinion on this comment though -
{code}
I had to implement this test as a "cloud" test so as to enable testing these
core level operations (since these operations are enabled only in the cloud
mode). The collection-level changes include,
- Backup/restore collection metadata
- Check the version compatibility during restore
- Strategy interface to define "how" backup operation is performed (e.g.
copying the index files vs. a file-system snapshot etc.)
{code}
I feel the first point should be part of this Jira . We can then say this patch
effectively solves makes the repository interface work for both standalone and
cloud.
Points 2/3 seem more like better guarantee checks and more options and aren't
cloud related. We could tackle that in SOLR-9055

> Currently when we create a backup we use SimpleFSDirectory to write the
> backup indexes. Similarly during a restore we open the index using
> FSDirectory.open .
> We should provide a param called {{directoryImpl}} or {{type}} which will be
> used to specify the Directory implementation to backup the index.
> Likewise during a restore you would need to specify the directory impl which
> was used during backup so that the index can be opened correctly.
> This param will address the problem that currently if a user is running Solr
> on HDFS there is no way to use the backup/restore functionality as the
> directory is hardcoded.
> With this one could be running Solr on a local FS but backup the index on
> HDFS etc.
