Does Okera support the "LIMIT" predicate push down?
We currently do not support pushdown of "limit". We expect the compute engine to get the data from ODAS and then do the limiting.
If the intent is to scan one partition, we recommend using a "where" predicate. ODAS supports partition pruning, based on the filter. For example: where year=2017, month='Mar', we would hit only that partition.
