--------------------------------------------
Summary: Add note for CopyTable section explained it does not
perform a diff, but a full write from source to target
Key: HBASE-21462
URL: https://issues.apache.org/jira/browse/HBASE-21462
Project: HBase
Issue Type: Improvement
Components: documentation
Reporter: Wellington Chevreuil
Assignee: Wellington Chevreuil
Performance is a common issue with CopyTable is when the key/time range for the
data to be copied is large because it basically scans all rows on the specified
range, in the source and perform related puts on the source. We should add
extra note explaining that on the reference guide, to help users/admins
understand when to choose between the different tools/approaches for syncing
clusters.
