Constructs the kinesis partitioner for a targetTable based on the currently set tableOptions.

The following rules are applied with decreasing precedence order.

• If targetTable is partitioned, return a RowDataKinesisPartitioner.
• If the partitioner type is not set, return a RandomKinesisPartitionKeyGenerator.
• If a specific partitioner type alias is used, instantiate the corresponding type
• Interpret the partitioner type as a classname of a user-defined partitioner.

Parameters:

tableOptions - A read-only set of config options that determines the partitioner type.

physicalType - Physical type for partitioning.

partitionKeys - Partitioning keys in physical type.

classLoader - A ClassLoader to use for loading user-defined partitioner classes.
