`chain_traverse` traverses the chain for all hashes matching on the build side matching the hash on the probe side. If the build side is larger and every probe value matches many build side hashes, this algorithm is known to be not very (cache) efficient. One thing to consider is implementing a different algorithm for the hash join. -- This is an automated message from the Apache Git Service.
