[jira] [Commented] (IGNITE-13510) Getting status of snapshot execution via command line and jmx

["Pavel Pereslegin (Jira)" <ji...@apache.org>]

Sorry for the late response.

It's a great idea to combine snapshot commands (create/restore) to improve UX.

I think we will rework other restore commands in the near future to comply with the following general syntax.
{noformat}
control.(sh|bat) --snapshot restore snapshot_name [--groups group1,...groupN] [--src path] [--sync]
control.(sh|bat) --snapshot status
control.(sh|bat) --snapshot cancel --id=operationId
{noformat}
The operation ID is needed to avoid possible errors when canceling the operation.

So we need to display this ID in status. I suggest to use first 4 bytes from request UUID (as a hexadecimal value).
For example, for request ID "{*}f6b2ac51{*}-fa90-462e-85d3-caecdf6cc2f4" we can display operation ID "{*}f6b2ac51{*}".

In addition, we should also display the "estimated" progress of the operation (create/restore).

We can rely on the following metrics:

create: CurrentSnapshotTotalSize / CurrentSnapshotProcessedSize
restore: totalPartitions / processedPartitions

So from my point of view the status output should be something like:
{noformat}
  Operation "f6b2ac51" to create/restore snapshot "snapshotName" is running on the following nodes:
    gridCommandHandlerTest0: 78% complete (estimated)
    gridCommandHandlerTest1: 23% complete (estimated)
{noformat}
WDYT?
Do you plan to continue working on this patch?
