Andrew Purtell updated HBASE-11764:
-----------------------------------
Attachment: HBASE-11764.patch
Updated patch. Requires HBASE-11763 be applied first. Includes a unit test that
verifies cell TTLs can expire a cell early. Notes on current implementation:
- Cell tags cannot extend the lifetime of a cell beyond the family setting
- If a cell has multiple TTLs we resolve the conflict by using the first TTL
tag encountered
- Unlike in schema cell TTLs are stored in milliseconds, no need to convert
I spent some time looking at doing more, i.e. letting cell TTLs override family
settings in all cases, but we have whole storefile early out optimizations that
would have to be undone potentially. If it is agreeable that cell TTLs can
specify a lifetime <= family setting, then implementation is easier. Otherwise
I think we should move this out of .6.
