> Cleanup the docs saying "HTable use write buffer"
> {code}
> Default size of the HTable client write buffer in bytes. A bigger buffer takes more memory — on
both the client and server side since server instantiates the passed write buffer to process
it — but a larger buffer size reduces the number of RPCs made. For an estimate of server-side
memory-used, evaluate hbase.client.write.buffer * hbase.regionserver.handler.count
> {code}
> {code}
> Put either adds new rows to a table (if the key is new) or can update existing rows (if
the key already exists). Puts are executed via Table.put (writeBuffer) or Table.batch (non-writeBuffer).
> {code}
