profilecli query local or remote blocks

[aleks-p]

The profilecli query commands issue a query towards a Pyrosope server (a query frontend).

It would be nice to have a similar command that works on one or more local or remote (object storage) blocks. This would help in cases where we observe issues in the read path that are related to the data and we can't easily reproduce them.

Example usage

profilecli query block series --local-path <path-to-a-local-dir-containing-blocks>
profilecli query block merge --local-path <path-to-a-local-dir-containing-blocks>
profilecli query block series --bucket-name dev-us-central-0-profiles-dev-001-data --block-ids <one-or-more-block-ids>
profilecli query block merge --bucket-name dev-us-central-0-profiles-dev-001-data --block-ids <one-or-more-block-ids>
