Due to the fact that Cassandra supports only
=, <, >, ....
IN (....)
... AND ...

When we have single single-valued range, we use =.
When we have single range, we use low bound < x AND x < high bound (or <= when appropriate)
When we have multiple single-valued range, we use IN (...).
In all other cases, including when IN is not supported in Cassandra,
we push down min/max bounds (domain.getValues().getRanges().getSpan())
using low bound < x AND x < high bound (or <= when appropriate)
