Method Detail

testBasics

public void testBasics()

testFileMetadataColumnSelection

public void testFileMetadataColumnSelection()

Test including file metadata (AKA "implicit columns") in the project list.

testPartitionColumnSelection

public void testPartitionColumnSelection()

Verify that partition columns, in any case, work.

testRevisedWildcard

public void testRevisedWildcard()

Test wildcard expansion.

testLegacyWildcardAndFileMetadata

public void testLegacyWildcardAndFileMetadata()

Combine wildcard and file metadata columns. The wildcard expands table columns but not metadata columns.

testLegacyWildcardAndFileMetadataMixed

public void testLegacyWildcardAndFileMetadataMixed()

As above, but include implicit columns before and after the wildcard.

testRevisedWildcardAndPartition

public void testRevisedWildcardAndPartition()

Include both a wildcard and a partition column. The wildcard, in legacy mode, will create partition columns for any partitions not mentioned in the project list.

Tests proposed functionality: included only requested partition columns.

testPreferredPartitionExpansion

public void testPreferredPartitionExpansion()

testPreferedWildcardExpansionWithOverlap

public void testPreferedWildcardExpansionWithOverlap()

testShadowed

public void testShadowed()

Verify that names that look like metadata columns, but appear to be maps or arrays, are not interpreted as metadata. That is, the projected table map or array "shadows" the metadata column.
