mongoq: is mongoq support local backup?

hong318500 commented 7 years ago

strata supports local backup, is mongoq support local query? checked mongoq --help and seems no options for local backup query.

Currently, mongoq only queries S3

If anyone is interested in adding support for mongoq querying local backups, here are some steps:

Make sure that the mongod processes started by mongoq cannot modify the backed-up SST files. A few ways to do this:
- Make sure that lstorage creates read-only copies of SST files upon backup, and restores appropriate permissions upon restore. This seems like the cleanest way.
- Or start mongod read-only. This might require you to enable authentication and create read-only users.
- Or use a read-only FUSE filesystem like rofs
Modify mongoq's command-line flags to use the backup directory or rofs instead of mounting S3
