Detailed Description

template<typename T>
class turi::hash_bucket< T >

Storing elements that gets hashed to the bucket in sorted order.

The container has an in memory buffer, and is backed by an sarray segment. When the buffer is full, it is sorted and written into the sarray segment as a sorted chunk.

The sort_and_write function then merges the sorted chunks and output to the destination array.
