Method Summary

Modifier and Type	Method and Description
void	testDisjointMapProjection() Test disjoint projection, but with maps.
void	testDisjointSchema() Verify that a disjoint schema (projection does not overlap with table schema) is treated the same as an empty projection.
void	testEmptyMapProjection()
void	testEmptyTopSchema() Verify that empty projection works: allows skipping rows and reporting those rows as a batch with no vectors but with the desired row count.
void	testNonEmptySchema() Verify that skip rows works even if the the projection is non-empty.

Method Detail

testEmptyTopSchema

public void testEmptyTopSchema()

Verify that empty projection works: allows skipping rows and reporting those rows as a batch with no vectors but with the desired row count.

testDisjointSchema

public void testDisjointSchema()

Verify that a disjoint schema (projection does not overlap with table schema) is treated the same as an empty projection.

testNonEmptySchema

public void testNonEmptySchema()

Verify that skip rows works even if the the projection is non-empty.

testEmptyMapProjection

public void testEmptyMapProjection()

testDisjointMapProjection

public void testDisjointMapProjection()

Test disjoint projection, but with maps. Project top-level columns a, b, when those columns actually appear in a map which is not projected.
