This is a Path of Exile stash tab indexer based on boltdb aimed at maximum performance with minimal disk space.
All tests are in dbTest and test only functionality exposed by db.
Crossed out indicates didn't work out.
Bucketing IDs into temporally and value-wise similar
Compression of index values overhead was too high for our workload, may revist in future with added metadata and optional compression based on workload in IndexEntry.
Set pooling clearing maps costs too much between IndexQueries. Switching to bitsets, both dense and sparse end up with significantly poorer performance. Did not try roaring bitmaps.
