---------------------------------
Summary: Support updates and deletes in transactions
Key: KUDU-3261
URL: https://issues.apache.org/jira/browse/KUDU-3261
Project: Kudu
Issue Type: Improvement
Components: tablet, transactions
Reporter: Andrew Wong
Kudu currently only supports multi-row, multi-partition transactions for INSERT
and INSERT_IGNORE operations. We should consider extending the Kudu tablet
store to support:
- Tracking Mutations in the MRS that are associated with a transaction
- Maintaining a separate DeltaTracker (i.e. DMS and multiple DeltaFiles) per
rowset per transaction
The DeltaReaders for the DRSs should consider the transaction's finalized
commit timestamp (or lack thereof) in the same way that the MRS iterator
considers mutations in the context of a snapshot.
