Method Detail

getProperties

public Properties getProperties()

This sets a very low threshold for the #of index segment bytes which can be incorporated into the accepted view for an incremental build. The unit test below will run until it has exceeded this threshold so that it can verify use cases where all sources are accepted and the build is actually a compacting merge as well as cases where only an ordered subset of the sources are accepted, which is the true incremental build (the use case when there is only data on the journal also qualifies as a compacting merge since we are able to discard deleted tuples).

Overrides:

getProperties in class AbstractResourceManagerTestCase

Returns:

A Properties object that supplies bindings for property names according to the described hierarchy among property resources. The returned Properties is NOT cached. TODO This does not handle the recursive truncation of the class name to search for "test.properties" yet.

test_builds

public void test_builds()
                 throws InterruptedException,
                        ExecutionException

Test maintains ground truth and writes on an index partition and performs a controlled overflow operation in which we do an index partition build. After each overflow we re-verify the index partition against ground truth. The process stops once we do an incremental build which does not result in a compact view.

Note: If an index partition view has only a little bit of data, then the "build" operation will actually incorporate all sources in the view, in effect doing a compacting merge instead of an incremental build in an effort to keep down the complexity of the view when that can be done with little cost. Therefore, it actually takes several passes before we have enough data on hand to take the code path which does an incremental build rather than a compacting merge.

Throws:

InterruptedException

ExecutionException
