Owen O'Malley updated HIVE-6060:
--------------------------------
Attachment: acid-io.patch
This is still a work in progress, but it shows the path:
* Adds AcidInputFormat and AcidOutputFormat interfaces for input/output formats
that can support the acid requirements.
* Extends OrcInputFormat and OrcOutputFormat to implement the interfaces.
* Adds AcidUtils that provides general routines to analyze the partition
directory and figure out which base and deltas to use.
* Doesn't change the behavior of the insert commands, which will still write
the traditional hive file layout. This will change later when we add command
support.
* The input format in getsplits will detect whether there are new or old style
layouts and read them appropriately.
* Java clients can write the new layout by using the RecordUpdater interface.
* There are raw interfaces for the compactor to use.
> Define API for RecordUpdater and UpdateReader

> We need to define some new APIs for how Hive interacts with the file formats
> since it needs to be much richer than the current RecordReader and
> RecordWriter.
