Hi,
If I use Fuseki's SOH to import my data into TDB store, tdbstats returns
zero results for my dataset. If I use tdbloader to import my data I get
proper results and I see a stats.opt being created inside the dataset
directory.
Is this expected behaviour?
Yes - it's not ideal though.
The stats file isn't maintained by the usual incremental API calls --
only the loaders know to automatically create "stats.opt".
The original reason was that the expected usage was large(ish) initial
load and smaller incremental changes so the basic stats (and it's only
the relative numbers that matter) were still useful. that isn't always
the case, and transactions are going to make it worse.
What can help is to periodically run "tdbstats" on the database, and
we're in the same situation as e.g. posgresql.
