The status reports for the following tasks often refer to fetches (number_of_successful_fetches,number_of_failed_fetches, total_fetch_time_millis,fetch_exceptions). We also have a similar term (which is identical in meaning) call reads (number_of_concurrent_reads). We also have the generic operations_received and total_transferred_bytes and last_requested_seq_no.

On the write sides we have bulk (number_of_successful_bulk_operations, number_of_failed_bulk_operations) and writes (number_of_concurrent_writes, number_of_queued_writes <-- note the different semantics here).

I think we should align our terminologies across the various places. I personally like the read versus write and bulk vs ops. Howabout:

• number_of_succesful_bulk_reads
• number_of_failed_bulk_reads
• total_bulk_read_time
• number_of_ongoing_bulk_reads
• total_operations_read
• total_bytes_read
• last_requested_seq_no_for_reads
• number_of_successful_bulk_writes
• number_of_failed_bulk_writes
• number_of_ongoing_bulk_writes
• number_of_queued_ops_to_write (not too happy with this one)
