the data xfer through the > event will skip the disk entirely for this & also remove the extra IOPS > incurred. > This channel is not suitable for large-scale event transport, but > specifically the workload here deals with 1-row control tables which consume > more bandwidth with HTTP headers and hostnames than the 93 byte payload. -- This message was sent by Atlassian Jira (v8.3.2#803003)
