For optimization in that situation, Trino can compact the large Pushing down a large list of predicates to the data source can compromise Minimum size of query predicates above which Trino compacts the predicates. However, it can also increase latency for some queries. Using a large timeout can potentially result in more detailed dynamic filters.
