-----------------------------------
Summary: Clean up Filter package for post 1.0
Key: HBASE-13346
URL: https://issues.apache.org/jira/browse/HBASE-13346
Project: HBase
Issue Type: Bug
Components: API, Filters
Affects Versions: 2.0.0
Reporter: Lars George
Fix For: 2.0.0
Since we have a bit of a messy Filter API with KeyValue vs Cell reference mixed
up all over the place, I recommend cleaning this up once and for all. There
should be no {{KeyValue}} (or {{kv}}, {{kvs}} etc.) in any method or parameter
name.
This includes deprecating and renaming filters too, for example
{{FirstKeyOnlyFilter}}, which really should be named {{FirstKeyValueFilter}} as
it does _not_ just return the key, but the entire cell. It should be deprecated
and renamed to {{FirstCellFilter}} (or {{FirstColumnFilter}} if you prefer).
In general we should clarify and settle on {{KeyValue}} vs {{Cell}} vs
{{Column}} in our naming. The latter two are the only ones going forward with
the public API, and are used synonymous. We should carefully check which is
better suited (is it really a specific cell, or the newest cell, aka the newest
column value) and settle on a naming schema.
