Hello everyone. I'm having this problem with Table Manager. What can I do to resolve it?

I don't know what is causing "UnknownOperationException", however you should adjust your configuration to stop it creating hundreds of tables - whatever from date it is starting at is some years in the past.

DynamoDB has a limit of 255 tables per user by default, also it is a waste of time and resources to create tables you don't need.

If you still get the error, please post your full set of command-line arguments and any yaml files supplied to the table-manager.

To create table manager deployment, I'm using the file that we can find in this repo. I just change all the dates.

Looks like you are using dynamodb-local, and since the errors only appear on second sync I guess that component is failing the operation to read tags.
Similar report: hashicorp/terraform-provider-aws#529

[Serrvosky]

If I use the image that are in k8s dynamodb's file:

deangiberson/aws-dynamodb-local

That give the output in the comment above (my last comment -> #1484 (comment)).

Now i change to AWS Local DynamoDB image:

amazon/dynamodb-local

and this is my new log's file:

And only now I have some errors about tagging
There are any K8s example to put this working with another DB? Cassandra for example?

[bboreham]

I made a couple of PRs intended to improve matters. If you could try out the config one that'd be great.

(You can ignore the table-manager sync errors until midnight (UTC) Wednesday)

[Serrvosky]

@bboreham, Thanks. I will "follow" your PR then.

Hello @bboreham,

I already tryed deploy cortex project with your most recent changes, however and I'm still having problems with table manager deployment.

It's getting a huge headache deploying Cortex in K8s.

I think I didn't show yet all the scenario that I want to implement. I will leave here a scheme to show what I want to implement. If it's possible, please I would like to ear your opinion about the possibility of implement it.

Hello again @bboreham.

I tried again with AWS DynamoDB Free Tier and it works perfectly. I'm not sure, but probably, AWS just turn off some features of that docker image that are important to run Cortex.
