-----------------------------------
Summary: SegmentNodeState.fastEquals() can trigger two I/O
operations
Key: OAK-4558
URL: https://issues.apache.org/jira/browse/OAK-4558
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-tar
Reporter: Francesco Mari
Assignee: Francesco Mari
Fix For: Segment Tar 0.0.6
The implementation of {{SegmentNodeState.fastEquals()}} compares the stable IDs
of two instances of {{SegmentNodeState}}. In some cases, reading the stable ID
would trigger a read of an additional record, the block record containing the
serialized version of the segment ID.
This issue is about evaluating the performance implications of this strategy
and, in particular, if it would be better to store the serialized stable ID in
the node record itself.
