Kirill Tkalenko updated IGNITE-13327:
-------------------------------------
Description:
It would be useful to understand how long it will take to rebuild indexes,
since there can be a lot of data and indexes. Now there are following metrics
that allow to estimate approximately how many indexes are left to rebuild:
# IsIndexRebuildInProgress - rebuilding cache indexes in the process;
# IndexBuildCountPartitionsLeft - remaining number of partitions (by cache
group) to rebuild indexes for.
For a more accurate estimate, I suggest adding a metric for caches "Number of
keys processed when rebuilding indexes" with the name
"IndexRebuildKeyProcessed". This way we can estimate for cache how much index
rebuilding will take. To do this, we can get "CacheSize" and use new metric to
find out how many keys are left to process.
I also suggest adding methods:
# org.apache.ignite.cache.CacheMetrics#getIndexRebuildKeyProcessed
# org.apache.ignite.cache.CacheMetrics#IsIndexRebuildInProgress
