Small query language for filters
--------------------------------
Key: HBASE-1002
URL: https://issues.apache.org/jira/browse/HBASE-1002
Project: Hadoop HBase
Issue Type: Improvement
Components: filters
Reporter: Andrew Purtell
Priority: Minor
Improve the usability of filters by making them specifiable or executable using
a little query language.
For example:
col("entry:price") > 3 && (col("entry:name") = "ABC" || col("entry:name") =
"XYZ")
Can be implemented as a little language compiler that takes filter
specifications as input and builds the requisite hierarchy of filter API
classes and actions as emitted java code.
Can also be implemented using JRuby snippets sent to the regionserver for
execution, but this has troublesome security implications.
