------------------------------------------
Summary: Insanely memory consuming checkpoints in aipersist
Key: IGNITE-22664
URL: https://issues.apache.org/jira/browse/IGNITE-22664
Project: Ignite
Issue Type: Improvement
Components: persistence
Reporter: Philipp Shergalis
Every page in persistent page memory delta file uses ~15-20 kilobytes.
Examples. Inserting via storageUpdateHandler. No indexes:
- Inserting 1 row at a time, doing checkpoint after every insertion.
Checkpoint saves 7 pages, pageSize is 1024, but delta file created uses up 144
KB.
- Inserting million rows, every checkpoint with ~11000 pages creates delta
files of ~180 megabytes
