> When two 'in' criteria containing constant values on the same field are combined with an 'or', Teiid will combine the two into a single 'in' operation.
> Since Oracle (for example)  has a 1000 item limit on the 'in' values, if the resulting combined list contains more than 1000 values, it can no longer be pushed down into Oracle for execution.
