NVM - noted from these posts that Temporal is not compatible with AWS Keyspaces:

> [@AWS Keyspace as managed cassandra for Temporal](https://community.temporal.io/t/aws-keyspace-as-managed-cassandra-for-temporal/1762/4):
>
> It seems from that webpage that Keyspaces supports LWT actually: “Amazon Keyspaces (for Apache Cassandra) fully supports compare and set functionality on INSERT and UPDATE commands, which are known as lightweight transactions (LWTs) in Apache Cassandra. As a serverless offering, Amazon Keyspaces (for Apache Cassandra) provides consistent performance at any scale, including for lightweight transactions. With Amazon Keyspaces, there is no performance penalty for using lightweight transactions.”

> [@Running on Amazon Keyspaces](https://community.temporal.io/t/running-on-amazon-keyspaces/159/3):

> We’ve had a few requests for keyspaces so this is something we definitely want to support and I’m actively tracking it. Right now it seems like a few off the shelf hosted Cassandra solutions aren’t actually as compatible as we hoped so as Mark said, there is considerable work.
