Has the normalization process been updated? Unless I’ve done something wrong - which I can’t imagine what as this is a brand new source connected and I’m using the most recent versions - there really needs to be much better regression testing going on.
Hello there! You are receiving this message because none of your fellow community members has stepped in to respond to your topic post. (If you are a community member and you are reading this response, feel free to jump in if you have the answer!) As a result, the Community Assistance Team has been made aware of this topic and will be investigating and responding as quickly as possible.
Some important considerations that will help your to get your issue solved faster:
It is best to use our topic creation template; if you haven’t yet, we recommend posting a followup with the requested information. With that information the team will be able to more quickly search for similar issues with connectors and the platform and troubleshoot more quickly your specific question or problem.
Make sure to upload the complete log file; a common investigation roadblock is that sometimes the error for the issue happens well before the problem is surfaced to the user, and so having the tail of the log is less useful than having the whole log to scan through.
Be as descriptive and specific as possible; when investigating it is extremely valuable to know what steps were taken to encounter the issue, what version of connector / platform / Java / Python / docker / k8s was used, etc. The more context supplied, the quicker the investigation can start on your topic and the faster we can drive towards an answer.
We in the Community Assistance Team are glad you’ve made yourself part of our community, and we’ll do our best to answer your questions and resolve the problems as quickly as possible. Expect to hear from a specific team member as soon as possible.
Thank you for your time and attention.

@natalyjazzviolin actually, honestly thank you again for sharing that previous issue. This does seem to be a timeout issue with the source.
I broke the connector into separate connectors (one for each stream) and one still failed. It seems to hang until the timeout limit specified in the source configuration.
look at the time signatures

The destination config (snowflake credentials) were updated and the sync started working. but after a few incremental + dedupe syncs its started failing again. There are no failed queries in snowflake. It appears to be an issue with the source (or debezium).
To be clear: I have one MySQL source with 4 tables. Using that one connector I can sync all tables except for one. I have tried syncing one table, it successfully syncs, then i unselected it and select the other one and it fails. The connections are all the same, there are no existing SCD tables or anything.
The schema does not seem problematic.
The various tables are roughly the same size.
I can’t seem to understand what is going wrong from the logs.
@danieldiamond were you able to isolate this any further? We’ve been hitting issues on a few postgres sources where debezium fails to shut down correctly on syncs. Sometimes, it’ll work after a reset. Other times, no luck.
