MapKeyConditionals

Definition used to cast an index map column with keys indexed to a query-able definition. This will allow users to use "CONTAINS KEY" clauses to search for matches based on map keys.

T: The Cassandra table inner type.
R: The record type of the table.
K: The type of the key held in the map.
V: The type of the value held in the map.
returns: A MapConditionals class with CONTAINS KEY support.

The map column to cast to a Map column secondary index query.
final def containsKey(elem: K): builder.clauses.WhereClause.Condition

Generates a Map CONTAINS KEY clause that can be used inside a CQL Where condition.
Generates a Map CONTAINS KEY clause that can be used inside a CQL Where condition. This allows users to lookup records by a KEY inside a map column of a table.
Key support is not yet enabled in phantom because index generation has to be done differently. Otherwise, there is no support for simultaneous indexing on both KEYS and VALUES of a MAP column. This limitation will be lifted in the future.
elem
The element to check for in the contains clause.
returns
A Where clause.
