[GitHub] [hudi] prashantwason opened a new pull request, #8493: [HUDI-6098] Use bulk insert prepped for the initial write into MDT.
prashantwason opened a new pull request, #8493:
URL: https://github.com/apache/hudi/pull/8493
- [HUDI-6098] Use bulk insert prepped for the initial write into MDT.
### Change Logs
1. Added a flag to HoodieTableMetadataWriter.commit to specify if the commit is an initial commit
2. For initial commit, bulkInsertPrepped API is used
3. Added a partitioner for MDT bulk insert which partitions the records based on their file Group. Since the records are already tagged before calling commit, this partitioner can retrieve the fileID and partition from the current location of the record.
### Impact
Massive increase in read performance after initial creation of a index.
Reduces the large read/write IO requirement for the first compaction in MDT.
Reduces the duplicate storage of initial log files keeping the redundant initial commit data until cleaned.
Faster initial commit as bulkInsert is more performant for billions of records than upsert which has a workload profiling stage.
### Risk level (write none, low medium or high below)
None
Already covered by existing unit tests.
### Documentation Update
None
### Contributor's checklist
- [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute)
- [ ] Change Logs and Impact were stated clearly
- [ ] Adequate tests were added if applicable
- [ ] CI passed

Review Comment:
from what I glean, partitioning is based on fileGroupIndex disregarding the MDT partition. So, tell me something.
if we have 2 file groups in col stats and 2 file groups for RLI, does 1st file group for both col stats and RLI belong to same partition in this repartition call ?
should the partitioning be based on fileId itself and sorting within that can be based on the record keys within each partition. or am I missing something ?

Review Comment:
we know the total partitions is going to be equal to total file groups. can we override the "numPartitions" for FileGroupPartitioner?

Review Comment:
reason being, the argument "JavaRDD<HoodieRecord> records " to this method could contain records for N no of partitions in MDT. not sure if we are making any assumptions on that.
