Summary
CQL defines built-in data types for columns in Cassandra, which are unique counter types, date and time values, and UUIDs. CQL data types have strict requirements for conversion compatibility, and clustering columns have even stricter requirements. DataStax provides a free CQL training course to help users understand the language and use it.
