Define semantics of cell timestamps
-----------------------------------
Key: HBASE-2406
URL: https://issues.apache.org/jira/browse/HBASE-2406
Project: Hadoop HBase
Issue Type: Task
Components: documentation
Reporter: Todd Lipcon
There is a lot of general confusion over the semantics of the cell timestamp.
In particular, a couple questions that often come up:
- If multiple writes to a cell have the same timestamp, are all versions
maintained or just the last?
- Is it OK to write cells in a non-increasing timestamp order?
Let's discuss, figure out what semantics make sense, and then move towards (a)
documentation, (b) unit tests that prove we have those semantics.
