HeavyDB Backend

The table below contains the data structures available for the HeavyDB backend. It should be noticed that the following types are not regular Python types but Numba types.

The set of types below are only materialize inside the HeavyDB SQL Engine. Thus, one cannot create and use them inside the REPL, for instance.

heavydb.Array(size, dtype)	RBC Array<T> type that corresponds to HeavyDB ARRAY
heavydb.Column()	RBC Column<T> type that corresponds to HeavyDB COLUMN
heavydb.ColumnArray()	RBC Column<Array<T>> type that corresponds to HeavyDB COLUMN<ARRAY<T>>
