Что является лучшим способом, чтобы автоматизировать репликацию РДС (MySQL), а схемы в AWS красное смещение?

We use ruby scripts to migrate data from MySQL to Redshift(PostgreSQL).Currently we use YAML configuration files to maintain schema information (column names and types).So whenever a MySQL table is altered, we need to manually change the YAML files.Now, we are thinking of moving YAML configurations to database(PSQL) as JSON object. But still we need to manually change the schema configurations.We want to automate the process.(Preferably using Ruby.)

PS: We use bin-log to incrementally update data in AWS Redshift.
