implicit class MapKeyConditionals[T <: CassandraTable[T, R], R, K, V] extends AnyRef

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.

    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.

    mark

    The prepared query mark.

    returns

    A Where clause.
