Write related ORC files in the same directory using the same UUID
ClosedPublic

Authored by douardda on Mar 18 2022, 2:12 PM.

Details

Summary

related ORC files being ORC files involved in the serialization of a given
object type, namely:

  • snapshot and snapshot_branches,
  • revision and revision_history,
  • directory and directory_entry.

Also include the object_type in the generated file name (in place of the
static 'graph').

So the result will typically be like:

output/orc/shapshot/
  snaphot-18a575cb-3a92-4753-9267-e3475fa30857.orc
  snaphot_branch-18a575cb-3a92-4753-9267-e3475fa30857.orc
  snapshot-1f41d206-994a-49bb-917f-e096e40c2856.orc
  snapshot_branch-1f41d206-994a-49bb-917f-e096e40c2856.orc

Depends on D7384.

    - uuid
    - version of swh.model used at file generation time,

    Implement test_orc exporter as a simple function instead of a fixture
    
    and split it in 2 parts (needed for changes to come).

    Make the kafka group_id prefix configurable in the config file
    
    rather than hardcoding it to 'swh-dataset-export-', use the 'group_id'
    value from the 'journal' section of the config file as prefix, if given
    9otherwise default to the former value).
    
    This is needed because current auth policy of swh kafka cluster only allow
    group_id to start with the actual login for authenticated connection.
    So we need to be able to specify this group_id prefix.

    Update JournalClientOffsetRanges for swh.journal 0.9
    
    deserialize_message() now takes an optional 'object_type' argument.

    Encode TimestampWithTimezone as (sec, usec, offset) in ORC file
    
    instead of using the ORC Timestamp format, since we cannot always encode
    them in this format.
    
    The offset is encoded as binary (byte string), following recent evolutions
    of swh-model.
    
    This makes swh-dataset compatible with swh-model 5.

See https://jenkins.softwareheritage.org/job/DDATASET/job/tests-on-diff/35/ for more details.

Date:   Fri Mar 18 11:46:37 2022 +0100

    Encode TimestampWithTimezone as (timestamp, offset, raw_offset_bytes) in ORC file
    
    ie. use the standard ORC Timestamp format (aka a couple
    (seconds, nanoseconds)) with 2 extra fields for the offset.
    
    The offset is stored as an integer (in minutes), but the raw offset
    value is also present as a binary string representation, following
    recent evolutions of swh-model.

    Add some user metadata in generated ORC files
    
    add:
    - object type
    - uuid
    - version of swh.model used at file generation time,
    - version of swh.dataset used at file generation time.

    Implement test_orc exporter as a simple function instead of a fixture
    
    and split it in 2 parts (needed for changes to come).

    Make the kafka group_id prefix configurable in the config file
    
    rather than hardcoding it to 'swh-dataset-export-', use the 'group_id'
    value from the 'journal' section of the config file as prefix, if given
    9otherwise default to the former value).
    
    This is needed because current auth policy of swh kafka cluster only allow
    group_id to start with the actual login for authenticated connection.
    So we need to be able to specify this group_id prefix.

    Use a named logger for journalprocessor.py
    
    and add a few more debug logging statements.

    Update JournalClientOffsetRanges for swh.journal 0.9
    
    deserialize_message() now takes an optional 'object_type' argument.

    Encode TimestampWithTimezone as (timestamp, offset, raw_offset_bytes) in ORC file
    
    ie. use the standard ORC Timestamp format (aka a couple
    (seconds, nanoseconds)) with 2 extra fields for the offset.
    
    The offset is stored as an integer (in minutes), but the raw offset
    value is also present as a binary string representation, following
    recent evolutions of swh-model.
    
    This makes swh-dataset compatible with swh-model 5.

    Write related ORC files in the same directory using the same UUID
    
    related ORC files being ORC files involved in the serialization of a given
    object type, namely:
    
    - snapshot and snapshot_branches,
    - revision and revision_history,
    - directory and directory_entry.
    
    Also include the object_type in the generated file name (in place of the
    static 'graph').
    
    So the result will typically be like:
    
      output/orc/shapshot/
