-------------------------------------------
Summary: Tracking progress of index building
Key: IGNITE-10067
URL: https://issues.apache.org/jira/browse/IGNITE-10067
Project: Ignite
Issue Type: Bug
Reporter: Stanislav Lukyanov
When a new index is being created or indexes are being rebuilt in case a node
is restarted without index.bin, the performance of queries is low until the
index is ready. It would be good to track the process of indexing to have an
approximate completion time.
Currently we only have "started" and "finished" messages in the logs for each
index.
It would be good to also know
- All indexes to be built
- Number (+ percentage?) of processed entries (or pages, if it's hard to update
progress for each entry)
- Number (+ percentage?) of entries left
It seems reasonable to start collecting this data and just print it in the logs
for now. `metricsLogFrequency` could be reused as the frequency of logging.
After community has some experience with using this, this metrics could be
exposed via Java API/JMX/etc.
