Hi all, I have a question about Flink CDC for Postgres, and it’s parallelism. According to the documentation the parallelism should be set to 1 to ensure the ordering. How does this setting relate to the number of taskmanagers used in the cluster?
Some background about my use case:
• I use Table API,
• Postgres CDC as source connector for a bunch of different tables (8),
• In the pipeline I join the different tables and perform transformations/group by operations,
• Opensearch as the sink
Because there are multiple CDC sources, would it be possible to scale up the number of taskmanagers from 1 to, say 8 (=number of CDC connectors), to speed up the process?
