Since Bug 1896609 landed we now have Glean & Firefox on Glean (FOG) memory reporting built into the Firefox Memory Reporter.
This allows us to measure the allocated memory in use by Glean and FOG.
It currently covers memory allocated by the C++ module of FOG and all instantiated Glean metrics.
It does not yet measure the memory used by Glean and its database.
Maintenance of rdb-rs, the Redis database format utility, is moving to @bimtauer.
Tim recently worked on improvements and updates and approached me to take over the crate.
I merged his patches, released 0.3.0 and will now hand over crate ownership.
