Exceeded the number of columns that can be updated simultaneously

Question

I'm trying to load data to the Amazon Keyspaces Managed Cassandra. It's working fine for some of the simple objects but when I tried to load a table with 286 columns im getting the error

Exceeded the number of columns that can be updated simultaneously

Can someone help?

Below is my code

var batch = mapper.CreateBatch(BatchType.Unlogged)
                    .WithOptions((options) => options
                    .SetConsistencyLevel(ConsistencyLevel.LocalQuorum));
                lines.ForEach((item) =>
                {
                    batch.Insert(item);
                });
                mapper.Execute(batch);

Answer 1

There is a quota defined in Amazon keyspaces (for Apache Cassandra). Max row size by default is 1MB. You can refer the quotas here https://docs.aws.amazon.com/keyspaces/latest/devguide/quotas.html . I think you need to update max row size value.

Answer 2

The error is because of the Max table schema size. The maximum size of a table schema is 350 KB.

Here is the documentation: https://docs.aws.amazon.com/keyspaces/latest/devguide/quotas.html
