Aleksey Plekhanov commented on IGNITE-11998:
--------------------------------------------
Data page scan also conflicts with multi-page in-place updates. See disable
multi-page in-place updates in CacheDataStoreImpl#canUpdateOldRow if data page
scan will be enabled. (See IGNITE-29028)
> Fix DataPageScan for fragmented pages.

> Fragmented pages crash JVM when accessed by DataPageScan scanner/query
> optimized scanner. It happens when scanner accesses data in later chunk in
> fragmented entry but treats it like the first one, expecting length of the
> payload, which is absent and replaced with raw entry data.
