2019/11/26 - AWS RDS DataService - 2 updated api methods
Changes Update rds-data client to latest version
{'parameterSets': {'typeHint': 'DATE | DECIMAL | TIME | TIMESTAMP'}}
Runs a batch SQL statement over an array of data.
You can run bulk update and insert operations for multiple records using a DML statement with different parameter sets. Bulk operations can provide a significant performance improvement over individual insert and update operations.
