Thomas Mueller updated OAK-10577:
---------------------------------
Description:
Currently, we have very few metrics per repository, and most are for the whole
repository: total size, the total index sizes, datastore size. The only metric
we collect per path is the approximate number of nodes per path.
I would like to collect more data, first via a "flat file store" (sorted list
of node data), e.g.
* Approximate number of nodes per path.
* Approximate size of binaries per path.
* Histograms of binary sizes.
* The same, but for a filtered set of binaries.
* Number and size of distinct binaries.
* Number of distinct values per (indexed) property, and the top values. This is
useful to improve cost estimation (the "weight" property of indexes) and
estimate index sizes.
