mayankshriv opened a new pull request #6977:
URL: https://github.com/apache/incubator-pinot/pull/6977
Enhanced the existing endpoint for table deugging on controller as well as
server
to include segment state transition and consumption related errors and
information.
Note: This is a debug endpoint and should not be expected to maintain
backward compatibility
from user's perspective. It would, however, ensure that debug calls from
controller to
servers maintain compatibility.
- TableDataManager now caches exceptions caused during segment consumption
or state transition.
Currently, only 100 exceptions are stored in each TableDataManager.
- Table debug endpoint on server now returns:
- Segment name and size
- Consumption info
- Error info
- Table debug endpoint on the controller returns aggregated segment info's
across all server
in addition to existing broker and server info's.
- By default, only segments with issues are reported. To report all
segments, an optional
parameter `verbose=true` can be specified in the api call.
