It probably isn't feasible, but the ideal way to run such a query is to pre-partitioning the `data` table such that each distinct value of `fact_id` is only stored on one node. (this is how Vertica does this type of join, FWIW) If re-partitioning the entire data table is too large, you could potentially only repartition a projection of `fact_id` (to quickly know what rows aren't matching) 🤔 -- This is an automated message from the Apache Git Service.
