Subject [jira] [Commented] (HBASE-7899) Cell block building tools: Cell codec and means of iterating an objects Cells
Date Thu, 21 Feb 2013 21:52:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7899?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583579#comment-13583579
] 

stack commented on HBASE-7899:
------------------------------

Try rb again.

On comments so far, I just moved CellTool.  I think it fine being private for now.

Will not address the deep copy issue in encoders until we have more than one KV implementation
going on in hbase.

Keep coming w/ the comments.

> 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
