Timothy Farkas commented on APEXMALHAR-2048:
--------------------------------------------
Update on progress. I have finished three building blocks and their unit tests.
1. A priority queue which keeps track of LRU elements.
2. A window bounded cache which has a max size size, and removes least recently
used elements on endwindow.
3. A simple identifier generator for Spillable datastructures.
I also have most of the basic implementation for a SpillableArrayList,
SpillableMap, and SpillableArrayListMultimap done. I will do some refactoring
to pull out some common code into abstract classess and make the abstract
classes depend on the BucketedState interface, so that future implementations
that want to spill into a different backing store will just have to implement
the BucketedState interface. Will provide another update later in the week.
> Create concrete implementation of ArrayListMultiMap using managed state.
