uint8_t foedus::storage::hash::HashPartitionerData::bin_bits_

Definition at line 116 of file hash_partitioner_impl.hpp.

PartitionId foedus::storage::hash::HashPartitionerData::bin_owners_[8]

partition of each hash bin.

Actual size is total_bin_count_. If !partitionable_, we don't even allocate memory for this part.
