QUESTION
Recently I'm reading the code associates with how bookkeeper writes indexes for a ledger, and there is a piece of logic about grab an available LedgerEntryPage from cache.
step 1: Try to get a available page from listOfFreePages
step 2: reset the page
step 2.1: reset the metadata, including set the entryKey to new EntryKey(-1, -1)
step 2.2: put the LEP into lruCleanPageMap, note the key is new EntryKey(-1,-1)
step 3: Reassign the entryKey of LEP with new EntryKey(ledgerId, firstEntryId)
step 4: increment the use count and remove LEP with the reassigned entryKey, but it can't remove the page since the key is different.
We have a productive error about "Trying to update a dirty page" and I'm not sure it matters, would be appreciate if someone will reply on it.
