Functions

partition_table

Computes up to num_workers - 1 partition boundaries that divide the primary key space into num_workers roughly even partitions. At most max_probed_prefixes prefixes are probed in MySQL to bound the time spent. Each prefix probe costs a few queries that should each be quick (index dives, instead of table scans).
