> The prototyping work in IMPALA-9382 revealed some hard trade-offs between
> having a full-fidelity text profile and readability.
> We want to have a text profile with less information by default so that it is
> more readable, and rely on the thrift profile for more detailed debugging.
> This would be easier if we provided a utility that can pretty-print a thrift
> profile at different levels of detail.
> This JIRA is to reduce the default level of pretty-printing for aggregated
> profiles, but provide a utility that can dump both the basic and full
> versions. My thought is to start off with the same 4 levels as explain, but
> maybe only implement 2 levels to start off with - basic and extended.
> The utility should be able to handle the same cases as
> bin/parse-thrift-profile.py (profile log and single profile in a file) and
> maybe print only a specified query from a profile log. We can use the
> DeserializeFromArchiveString() method that was removed in IMPALA-9381, then
> pretty-print the deserialised profile.
