------------------------------------
Summary: Disallow non-atomic update operations when TIMELINE
consistency is enabled
Key: HBASE-11634
URL: https://issues.apache.org/jira/browse/HBASE-11634
Project: HBase
Issue Type: Improvement
Components: Client, Usability
Affects Versions: 0.99.0, hbase-10070
Reporter: Nick Dimiduk
Something to consider for the HBASE-10070 line of changes. When a client reads
a timeline consistent view of data, read-update-write operations are
potentially destructive. When a client is accepting TIMELINE reads, we should
only allow server-side atomic update operations.
In a future state, we could offer a CRDT-based data type to further extend the
set of write operations that are guaranteed safe under this consistency model.
I may not have the semantics of the new client API correct, but this is the
idea: do what we can to protect users from the major dangers of this relaxed
consistency model.
