Hi Andy,
Sorry for the late answer, but I was quite busy.
The database was as far as I can tell generated in version 4.7.0 and then
upgrades to 4.8.0 and 4.9.0 were done. Datasets were created (and some
deleted and created again) in all these versions.
The scenario that my colleague had

The database is opened before the configuration is processed.
Also, there is only one

This looks like the configuration that you need:

The TDB2 database is open for general use (i.e. write).
You can get read-only by restricting the operations on the dataset to
only query and the read functions of the Graph Store Protocol.
Being SPARQL, query operations and write (update) operations are
separate by syntax and there are
I think it depends more on query than with the back end, but don't have
detailed comparisons. Perhaps others do.

Thanks, maybe that would be a good fit. Do you know how query performance
compares running over HDT compared to TDB2? Or is that question is too
dependent on the particular queries to answer?

Perhaps https://www.rdfhdt.org/manual-of-hdt-integration-with-jena/ will
suit your need.

Hi,
Is it possible to run a Fuseki server using a read-only TDB2 directory? I’d
like to run a query-only SPARQL endpoint, no updates. However I get an
exception at startup if the filesystem is read-only. Does Fuseki need to
acquire the lock even if updates are turned off?
Thank you,
Jim
