Subject [jira] [Updated] (HBASE-7899) Cell block building tools: Cell codec and means of iterating an objects Cells
Date Sat, 23 Feb 2013 00:08:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-7899?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HBASE-7899:

    Attachment: 7899v2.txt

v2 addresses the nice reviews I got up on rb.  All but some nits about null checking equals
and speeding up the cellcodec accommodated.

Fix javadoc warnings too.  Hard to see findbug report locally so will submit here and review
whatever is produced.

Uploading to rb too.

> In our rpc specification, https://docs.google.com/document/d/1-1RJMLXzYldmHgKP7M7ynK6euRpucD03fZ603DlZfGI/edit#,
we talk of passing lots of Cells outside of protobuf.  We do it using Cell blocks. There are
blobs filled with Cells that are encoded variously and optionally compressed.
> This issue is about adding to hbase-common basic facility for building Cell blocks. 
It includes a codec Interface for encoding/decoding Cell blocks as well as a means of iterating
an objects Cell content (prefix-tree's CellScanner).
> This is a subtask of HBASE-7898 Serializing Cells over RPC
