repair: Speed up ranges calculation when small table optimization is on Normally, during bootstrap, in repair_service::bootstrap_with_repair, we need to calculate which range to sync data from carefully for the new node. With small table optimization on, we pass a single full range and all peer nodes to row level repair to sync data with. Now that we only need to pass a single range and full peers, there is no need to calculate the ranges and peers in repair_service::bootstrap_with_repair and drop it later. The calculation takes time which slows down bootstrap, e.g., ``` Jul 08 22:01:41.927785 cluster-scale-50-200-test-scayle-t-db-node-51209daa-93 scylla[5326]: [shard 0:strm] repair - bootstrap_with_repair: started with keyspace=system_distributed_everywhere, nr_ranges=23809 Jul 08 22:01:57.883797 cluster-scale-50-200-test-scayle-t-db-node-51209daa-93 scylla[5326]: [shard 0:strm] repair - repair[79eac1a1-5d5b-4028-ae1c-06e68bec2d50]: sync data for keyspace=system_distributed_everywhere, status=started, reason=bootstrap, small_table_optimization=true ``` The range calculation took 15 seconds for system_distributed_everywhere table. To fix, the ranges calculation is skipped if small table optimization is on for the keyspace. Before: cluster dev [ PASS ] cluster.test_boot_nodes.1 104.59s After: cluster dev [ PASS ] cluster.test_boot_nodes.1 89.23s A 15% improvement to bootstrap 30 node cluster was observed.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
