Subject [GitHub] orc pull request #179: ORC-255
Date Mon, 16 Oct 2017 22:40:12 GMT
GitHub user alanfgates opened a pull request:

    https://github.com/apache/orc/pull/179

    ORC-255

    This is not ready for commit.  I'm just putting it up so people can start looking at it
and giving feedback.
    
    As noted in the JIRA, this only deals with ACID2 and the vector batch interface.
    
    This depends on an unreleased version of Hive's storage-api.  It also fails when running
TestRecordReaderImpl due to changes in storage-api's DiskRangeList.

commit 96026a342bf531c9c12b3cc8a127f33026cba6b9
Author: Alan Gates <gates@hortonworks.com>
Date:   2017-09-15T18:40:01Z

    WIP Ported parsing parts of Hive's AcidUtils into AcidDirectoryParser and supporting classes.
 Haven't finished the testing yet.

commit 12477e216caee814fd3c6545a3a7c938d54369b8
Author: Alan Gates <gates@hortonworks.com>
Date:   2017-09-26T22:57:50Z

    Finished testing AcidDirectoryParser.

    Changed AcidVersionedDirectory to track txn information for files in addition to just
FileStatus.

    Moved AcidVersionedDirectory to ParsedAcidDirectory to better fit with terminology of
AcidDirectoryParser and ParsedAcidFile.  Added ability to determine whether a given input
file from the directory should be read and to determine which delete deltas to use for a given
input file.  Fixed a number of bugs I found along the way.

    Added ability to read insert files (base and normal delta).  Haven't yet done delete files.

commit b8a7e6d7da40e83d193140d565463caf83379ee1

Date:   2017-09-30T00:59:09Z

    WIP, wrote the initial code for handling the deletes.  Haven't tested it yet.

commit 9146dd6020d63694e0b5773b2f092c102e78b0da
Author: Alan Gates <gates@hortonworks.com>
Date:   2017-10-03T19:54:09Z

    Fixed a bunch of errors in delete handling.  Added unit tests for delete testing.

commit 90ff039b83c2a198b5b7117b8c554c989a374af7

    Went overboard on caching delete sets.  I'm going to simplify this a bunch and remove
the caching.  But checking in now in case I change my mind and decide to go back to the caching.

commit acaabe6272e57e2bce0c9af5f74d61a2e1510709
Author: Alan Gates <gates@hortonworks.com>
Date:   2017-10-05T00:53:30Z

    Simplified delete sets to be attached to a ParsedAcidDirectory instead of trying to cache
them.  That leaves it up to the user to make sure there aren't too many ParsedAcidDirectories
live in a process, each with its own DeleteSet.

    Most likely useless changes.  I don't think I need the MergingAcidRecordReader.  But keeping
it for now in case I turn out to be wrong.  It has happened before.
