Lyuben Todorov commented on CASSANDRA-6572:
-------------------------------------------
I'm not too sure about the process of making the appends asynch for the
workload recording so I'd like to get some feedback on my idea before i go any
furher, it goes like this:
# Calculate how much space will be required from the query queue in a separate
function
# move the queue pointer ahead by that value
# submit the append in a separate thead where this is done using an executor
that gets shut down when the query logging is disabled or C* is shutdown.
And ofc remove the "synchronized" from {{QueryRecorded#append}}
> Workload recording / playback

> "Write sample mode" gets us part way to testing new versions against a real
> world workload, but we need an easy way to test the query side as well.
