Change subject: IMPALA-7527: add fetch-from-catalogd cache info to profile ...................................................................... IMPALA-7527: add fetch-from-catalogd cache info to profile Reapplies reverted IMPALA-7527. Adding a top-level entry to the profile broke downstream consumers. The change here is to add the additional stats to the summary profile. This patch adds a Java wrapper for a RuntimeProfile object. The wrapper supports some basic operations like non-hierarchical counters and informational strings. During planning, a profile is created, and passed back to the backend as part of the ExecRequest. The backend then updates the query profile based on the info emitted from the frontend. This patch also adds the first use case for this profile information: the CatalogdMetaProvider emits counters for cache hits, misses, and fetch times, broken down by metadata category. The emitted profile is a bit of a superset of the existing 'timeline' functionality. However, it seems that some tools may parse the timeline in its current location in the profile, so moving it might be incompatible. I elected to leave that alone for now and just emit counters in the new profile.
