 long bytesWritten)

Description copied from interface: BarrageSnapshotPerformanceSink

Record the cost of serving a single snapshot request.

Specified by:

log in interface BarrageSnapshotPerformanceSink

Parameters:

tableId - the identity of the snapshotted table

tableKey - the barrage performance key of the snapshotted table

requestTimeEpochNanos - the time at which the request was received, as nanoseconds since the epoch

queueNanos - the time the request spent queued before being serviced

snapshotNanos - the time spent constructing the snapshot

writeNanos - the time spent writing the snapshot

bytesWritten - the number of bytes written
