TDB2 cache configuration
I have been looking for information about cache configuration of TDB2 and
found the following document:
https://jena.apache.org/documentation/tdb/store-parameters.html
Does this document also apply to TBD2 or is there a similar document for
TDB2 somewhere?

It should do.

Christian - could you say a little about what you are trying to
configure for?

Almost all the documentation applied to both.
(and time to make TDB2 the "default" in the documentation)

Hi Christian,
I never had to use these settings....
Does this document also apply to TBD2
>
I searched for the first setting, block_read_cache_size, in
github.com/apache/jena, and found these settings in this TDB2 class:
https://github.com/apache/jena/blob/162f0ddfa2764ce926a2a00f59f6261657f29c5f/jena-tdb2/src/main/java/org/apache/jena/tdb2/params/StoreParamsConst.java#L29-L87
Doesn't mean 100% they are used, but it could be a starting point if you
want to start debugging until others reply here.
or is there a similar document for

I searched for some of the keys in that TDB2 class in the
github.com/apache/jena-site, but only found the page that you linked. So my
guess is that that page is missing for TDB2 (assuming the cache settings
are indeed used).
Cheers
