Does hbase scan or get is single threaded? Say I have hbase table with 100 regionservers.
When I scan a key rangle say a-z(distributed on all regionservers), will the client make calls to regionservers in parallel all at once or one by one.First it will get all keys from one regionserver then make a next call to another regionserver in lexicographic order of keys? If it makes call in parallel then how does it ensure result to be sorted by key always? Thanks!
