Key API adaptations: - Migrated from BigTableScanner to SSTableReader.getPositionsForRanges() API - Updated RepairRunnable references to RepairCoordinator (CASSANDRA-18816) - Fixed SSTableIntervalTree.build() to buildSSTableIntervalTree() - Updated Descriptor.baseFilename() to baseFile().name() - Updated AUTH_TABLE_NAMES to include CIDR_PERMISSIONS, CIDR_GROUPS, and IDENTITY_TO_ROLES for 5.0 - Changed from bytesOnDisk() to onDiskLength() for SSTable size calculations Includes bug fixes and features: - Improved observability in AutoRepair (CASSANDRA-20581) - Stop repair scheduler if two major versions detected (CASSANDRA-20048) - Safeguard Full repair against disk protection (CASSANDRA-20045) - Stop AutoRepair monitoring thread upon shutdown (CASSANDRA-20623) - Fix race condition in auto-repair scheduler (CASSANDRA-20265) - Minimum repair task duration setting (CASSANDRA-20160) - Preview_repaired auto-repair type (CASSANDRA-20046) patch by Paulo Motta; reviewed by Paulo Motta for CASSANDRA-19918 Co-Authored-By: Paulo Motta <paulo@apache.org> Co-Authored-By: Andy Tolbert <andy_tolbert@apple.com> Co-Authored-By: Chris Lohfink <clohfink@netflix.com> Co-Authored-By: Francisco Guerrero <frankgh@apache.org> Co-Authored-By: Himanshu Jindal <himanshj@amazon.com> Co-Authored-By: Jaydeepkumar Chovatia <jchovati@uber.com> Co-Authored-By: Kristijonas Zalys <kzalys@uber.com> Co-Authored-By: jaydeepkumar1984 <chovatia.jaydeep@gmail.com>
Adds a guard that blocks auto-repair when any cluster node has a version below 5.0.7 or an unknown version, ensuring the feature only runs when all nodes support it.
Introduces cassandra.autorepair.enable property (default: false) that completely disables auto-repair when set to false. When disabled: - No MBean registration - No service initialization - No scheduler setup - No bootstrap integration This provides a clean way to disable the feature at startup with no runtime overhead for supporting structures.
