`Parallel` vs `Partition` depends on the types of queries that you're matching against. `Parallel` hands all candidates to a blocking queue, so the synchronization overhead is per-query - efficient if the queries are heavy, but can be expensive if everything is just a term query and takes very little time to check. `Partition` collects all candidate queries, then divides them up into blocks and passes each block to a separate thread for checking. This will work better if all your queries are of a similar weight, but means that if a few heavy queries get pushed into a single partition then you can end up with longer latency. -- This is an automated message from the Apache Git Service.
