@rtpsw The rationale behind the hash caching / invalidation is unclear to me - if the purpose of the KeyHasher here is to compute the hash for each row in the batch, why don't we always keep a immutable tuple of <RecordBatch, std::vector<HashType>> to avoid in the queues to avoid dealing cache invalidation / mutation here? -- This is an automated message from the Apache Git Service.
