Ivan Rakov created IGNITE-11807: ----------------------------------- Summary: Index validation control.sh command may provide false-positive error results Key: IGNITE-11807 URL: https://issues.apache.org/jira/browse/IGNITE-11807 Project: Ignite Issue Type: Bug Reporter: Ivan Rakov Fix For: 2.8
There are two possible issues in validate_indexes command: 1. In case index validation is performed under load, there's a chance that we'll fetch link from B+ tree and won't found this key in partition cache data store as per it was conurrently removed. We may work it around by double-checking partition update counters (before and after indexes validation procedure). 2. Since indexes validation is subscribed to checkpoint start (reason: we perform CRC validation of file page store pages which is sensitive to concurrent disk page writes), we may bump into the following situation: - User fairly stops all load - A few moments later users triggers validate_indexes - Checkpoint starts due to timeout, pages that were modified before validate_indexes start are being written to the disk - validate_indexes fails We may work it around by triggering checkpoint forcibly before start of indexes validation activities. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
