Subject [jira] [Updated] (HBASE-7899) Cell block building tools: Cell codec and means of iterating an objects Cells
Date Sat, 23 Feb 2013 05:04:13 GMT

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

stack updated HBASE-7899:
-------------------------

    Attachment: 7899v3.txt

Break > 100 char lines (there is still at least one in the generated code so will probably
fail again).  Address the findbugs probs in hbase-common at least (the hbase-server ones are
all over the place -- don't seem to be me... will have a go at them though when do second
in the rpc patch series since its fun fixing the findbugs findings).

> 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
