Change subject: [KUDU-3447] Limit tablets copying speed
......................................................................
[KUDU-3447] Limit tablets copying speed
Copying tablets from one cluster to another is a high resource
consumed operation using the command : kudu
local_replica copy_from_remote. If the data size is very large,
the copying process will last for a long time. Other service
maybe get impacted and become unavailable because of the tablets
copying process cost too much disk and/or network bandwith.
Therefore it is better to limit the tablets copying speed and make
the system more stable. The goal is a trade-off the tablets copying
speed and the resource consumption.
As copy_from_remote is mainly downloading data from the remote
cluster and writing the data to local file system, it is better to
control the downloading speed to control the resource consumption.
This patch use a throttler to limit tablet copying speed.
Two paramters are added:
--tablet_copy_throttler_bytes_per_sec limits the copying speed,
and --tablet_copy_throttler_burst_factor limits the maximum
copying speed at a single time.
