David Alves commented on DRILL-13:
----------------------------------
for instance bloom filters can be used to perform a semi-join phase before a
distributed join.
Since bloom filters are usually associated with partitions I think bloom filter
capabilities would go along nicely with the partition information and as a
sub-api of SE e.g.:
{code}
interface PartitionInfo {
public enum PartitioningType {
NONE,ORDERED,RANDOM;
}
public enum BloomFitlerType {
NONE,KEY,COMPOUND;
}
public PartitionType partitionType();
public PartitionFunction function();
public BloomFilterType bloomFilterType();
}
{code}
That being said, for this particular issue maybe we could try and focus on the
main interfaces required and leave these details to other issues.

> We're going to need to define a storage engine API. At a minimum, we'll need
> to generate a Java one. We will probably need to also create a CPP one.
> This task is for the former. Things that are likely to be included in a the
> Java interface are: reader (scanner), writer, capabilities interface, schema
> interface, statistics interface, data layout and ordering
