Vincent Tran updated IMPALA-7034: --------------------------------- Description: Currently the practical limit for catalog topic update is in the neighborhood of 4GB - the fundamental limit of max thrift message size. This is an architectural limitation and not a resource limitation Larger enterprise clusters with high file counts can easily surpass this with normal usage. The high level ask here is for a more scalable implementation for metadata handling. The amount metadata that a cluster can handle should be proportional to the amount of hardware resource that an user is willing to allocate to it. was: Currently the practical limit for catalog topic update is in the neighborhood of 4GB - the fundamental limit of max thrift message size.
