Method Detail

mutateTuples

public int mutateTuples(List<Integer> columnIndexes,
                        List<List<org.apache.calcite.rex.RexLiteral>> tuples)

Mutate Kudu table using RexLiteral. Called while using a regular Statement

Parameters:

columnIndexes - the kudu indexes to mutate

tuples - a collection of rows to insert

Returns:

number of rows inserted

mutateRow

public int mutateRow(List<Integer> columnIndexes,
                     List<Object> values)

Mutate Kudu table using Object.

Parameters:

columnIndexes - the kudu indexes to mutate

values - a collection of rows to insert

Returns:

number of rows inserted

updateMutationState

protected void updateMutationState(Map<Integer,Object> colIndexToValueMap)

Creates a mutation for the row being inserted and adds it to the kudu session. Also calls updateMutationState() for all cube tables (if any exist).

Parameters:

colIndexToValueMap - Kudu index to new value mapping

flush

public void flush()

clear

public void clear()

Clears the cube mutation state (and thus frees up memory)
