> Creating TDB databases and attaching to existsing ones is quite fixed currently.   Any internal paramaters are quite difficult to manipulate and they are globals.
> Configurability of TDB databases has two dimensions:
> # Initial setup (e.g. block size)
> # Per JVM (e.g. cache sizes).
> (The file mode is actually a per JVM feature but should probably be regarded as an initial setup feature only.)
> With configurability, TDB and Fuseki could be scaled down for small databases and for many small databases in one JVM.
