Ivan Rakov created IGNITE-6033: ---------------------------------- Summary: Add sorted and multithreaded modes in checkpoint algorithm Key: IGNITE-6033 URL: https://issues.apache.org/jira/browse/IGNITE-6033 Project: Ignite Issue Type: Improvement Components: persistence Affects Versions: 2.1 Reporter: Ivan Rakov Assignee: Ivan Rakov Fix For: 2.2
Sequential writes to SSD are faster than random. When we write checkpoint, we iterate through hash table, which is actually random order. We should add an option to write pages sorted by page index. It should be configured in PersistentStoreConfiguration. Also, we already have PersistentStoreConfiguration#checkpointingThreads option, but we don't use it - we create thread pool, but submit only one task to it. This should be fixed as well. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
