Change in asterixdb[master]: ASTERIXDB-1566, ASTERIXDB-1733: Hash Group By and Hash Join ...
Hello Jenkins,
I'd like you to reexamine a change. Please visit
https://asterix-gerrit.ics.uci.edu/1056
to look at the new patch set (#24).
Change subject: ASTERIXDB-1566, ASTERIXDB-1733: Hash Group By and Hash Join conform to the memory budget
......................................................................
ASTERIXDB-1566, ASTERIXDB-1733: Hash Group By and Hash Join conform to the memory budget
- External Hash Group By now conforms to the memory budget (compiler.groupmemory)
- The maximum memory occupation of Hash Table in Hash Join conforms to the budget (join.memory)
- The number of hash entries (hash table size) is calculated based on an estimation of the aggregated
tuple size and possible hash values for the given field size in that tuple.
- Garbage Collection feature has been added to SerializableHashTable. For external hash group-by,
whenever we spill a data partition to the disk, we also check the ratio of garbage in the hash table.
If it's greater than the given threshold, we conduct a GC on Hash Table.
