Subject [jira] Updated: (HBASE-2274) [stargate] support specification of filters for scanners: JSON descriptors
Date Sun, 28 Feb 2010 20:24:05 GMT

     [ https://issues.apache.org/jira/browse/HBASE-2274?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-2274:
----------------------------------

    Attachment: HBASE-2274.patch

Updated patch. As before, extends Scanner entity to support filters. Filters are stringified
into JSON and passed as an optional entity attribute. 

Also extends Scanner entity to support specification of max versions.

Updates protobufs from 2.1.0 to 2.3.0. Might as well as I had to touch the proto files. 

Also tweaks o.a.h.h.filters:
  - Convert WritableByteArrayComparable into an abstract base class instead of an interface
  - Fix up implementors of WritableByteArrayComparable into subclasses
  - Add getters where necessary to support stringification

Still needs tests for new functionality. Working on them.

descriptions of filter structure as JSON.
