Subject [jira] [Commented] (COUCHDB-1266) Add stats field to _active_tasks
Date Tue, 30 Aug 2011 21:43:09 GMT

Adam Kocoloski commented on COUCHDB-1266:
-----------------------------------------

Totally agree that it's silly for us to be formatting status messages in the internals.  I
like what you've done here, Filipe, but I would have also supported a patch where a task was
specified as a simple property list.

> This proposal is simply to add a "stats" field to the _active_tasks results. This field
can be an arbitrary JSON value and each task can set it to whatever is appropriate for it.The
following patch also defines some basic stats for the existing tasks:
> 1) database compaction - # changes done, total changes, # of revisions copied, # of attachments
copied and progress (an integer percentage, same as what is exposed in the existing text field
"status");
> 2) view compaction - # of ids copied, total number of ids, # of kvs copied, total number
of kvs and progress
> 3) view indexing - # changes done, total changes, # inserted kvs, # deleted kvs, progress
> 4) replication - # missing revisions checked, # missing revisions found, # docs read,
# docs written, # doc write failures, source seq number, checkpointed source seq number, progress.
