This library exists as a standalone query builder designed to split every single element of a query to allow packages using the library to convert the query into a more performant query, or supporting functionality not available in the original database layer.


CQL (Cassandra) does not support CONCAT, so this can be pulled from the original query, the fields gathered and then concatinated in PHP.

When running a sharded database, the query can be rebuilt to execute across multiple nodes with the correct partitioning keys, and then presented back to the user as a single result.
