Todd Lipcon updated IMPALA-7034:
--------------------------------
Component/s: Catalog
> Increase scalability of metadata handling
> -----------------------------------------
>
> Key: IMPALA-7034
> URL: https://issues.apache.org/jira/browse/IMPALA-7034
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Affects Versions: Impala 2.13.0
> Reporter: Vincent Tran
> Priority: Major
>
> 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.
