Record the duration of specified op. For PUT, GET and GET_ALL use specific methods for those ops.

recordDeleteTime

public void recordDeleteTime(long timeNS,
                             long keySize)

Record the duration of specified op. For PUT, GET and GET_ALL use specific methods for those ops.

recordPutTimeAndSize

public void recordPutTimeAndSize(long timeNS,
                                 long valueSize,
                                 long keySize)

Record the duration of a put operation, along with the size of the values returned.

recordGetTime

                          long totalBytes,
                          long keyBytes)

Record the duration of a get operation, along with whether or not an empty response (ie no values matched) and the size of the values returned.

recordGetVersionsTime

public void recordGetVersionsTime(long timeNS,
                                  boolean emptyResponse)

Record the duration of a get versions operation, along with whether or not an empty response (ie no values matched) was returned.

recordGetAllTime

public void recordGetAllTime(long timeNS,
                             int requested,
