Summary: Improve WAL record/iterator structure Key: IGNITE-5322 URL: https://issues.apache.org/jira/browse/IGNITE-5322 Project: Ignite Issue Type: Improvement Components: cache Affects Versions: 2.1 Reporter: Alexey Goncharuk Fix For: 2.1 Currently, we rely on the WAL files layout and zero-ing to make a decision when to stop the iteration. Instead, we should write a WAL Pointer to each record with it's position in the file. This will allow us to verify that we are reading a consistent records sequence and should also remove a requirement for zero-clean WAL segment. When iterating over the WAL, we should calculate expected next WAL pointer and check that read pointer is equal to the read. If we found a difference, this means that we encountered a stale segment and can stop the iteration. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
