Which use case/requirement will be addressed by the proposed feature?

Right now we can only truncate string type with column.truncate.to.x.chars. We should also support array types since these can also be arbitrarily large for various databases and users may simply want a truncation option rather than the complexity of offloading payloads to an external data store.

Implementation ideas (optional)

Will put out a PR
