Method Detail

testOmittedValuesAtEnd

public void testOmittedValuesAtEnd()

Test "holes" in the middle of a batch, and unset columns at the end. Ending the batch should fill in missing values.

testOmittedValuesAtEndWithOverflow

public void testOmittedValuesAtEndWithOverflow()

Test "holes" at the end of a batch when batch overflows. Completed batch must be finalized correctly, new batch initialized correct, for the missing values.

testSkipRows

public void testSkipRows()

Test that omitting the call to saveRow() effectively discards the row. Note that the vectors still contain values in the discarded position; just the various pointers are unset. If the batch ends before the discarded values are overwritten, the discarded values just exist at the end of the vector. Since vectors start with garbage contents, the discarded values are simply a different kind of garbage. But, if the client writes a new row, then the new row overwrites the discarded row. This works because we only change the tail part of a vector; never the internals.

testSkipOverflowRow

public void testSkipOverflowRow()

Test that discarding a row works even if that row happens to be an overflow row.

testDefaultValues

public void testDefaultValues()

Verify that a default value set on the schema is used to fill missing required columns.
