Class TransactionExceedsPageCacheException

Namespace

Typhon.Engine

Assembly

Typhon.Engine.dll

A commit needs more of the page cache than the cache has: the pages it holds itself — its own dirty marks, and the pages its own epoch pin keeps — fill every slot a wait could get back, so no amount of waiting can serve it. Thrown before the commit's WAL append; the transaction is rolled back. Not transient: the same commit fails the same way. Commit in smaller batches, or enlarge the page cache.
