------------------------------------
Summary: Add a filter with containing semantic
Key: HBASE-25444
URL: https://issues.apache.org/jira/browse/HBASE-25444
Project: HBase
Issue Type: New Feature
Components: Filters
Affects Versions: 3.0.0-alpha-1
Reporter: Junsheng Tan
Say we want to check whether a cell value is within a set of values.
If the size of the set is 1000, we need to create 1000 SingleColumnValueFilter
with CompareOperator.EQUAL and wrap them with a FilterListWithOR. The scan
performance of these filters would be very bad.
But if we have a set filter, we just need to create only one filter with 1000
values. And the containing operation could be implemented as O(1) or O(log(n)).
This `SetFilter` is general and useful in my opinion, so would the community
consider to implement a `SetFilter`?
