Summary: Optimize entry transform operations. Key: IGNITE-8846 URL: https://issues.apache.org/jira/browse/IGNITE-8846 Project: Ignite Issue Type: Improvement Reporter: Alexei Scherbakov Assignee: Alexei Scherbakov 1. For pessimistic transactions entryProcessor is invoked twice if tx entry is already exists in [1] and after lock acquistion in [2] Actually this is enough to do it only once in postLockWrite. 2. Cache entry value is not needed on near node if EntryProcessor declares Void return type. We should try to detect this in runtime or provide some kind of annotation to mark EntryProcessor not caring about return value. This will bring huge performance benefit for transactions updating large values using transformations.
