Pull Request checklist
Current behavior : We issue a RocksDB write for each each iteration of partKey while traversing through lucene index during DS cardinality store calculation. For large indexes (10-12 billions), this could take up to 2 hours.
New behavior : Reducing the number of RocksDB write by in-memory aggregation up to a configured
flushCountafter which we issue bulk RocksDB writes.
