Hi, With memory mapped TDB storage (default with 64-bit JVM), the initial size of TDB store without any data at all is 200 MB, because most of index files are 8 MB, and there's quite a number of them. It may be a good number when loading big data sets, but is absolutely huge if an user expects to load only a bit of data.
In comparison, direct file method (with 32-bit JVM) makes only 8 KB index files resulting in only 200 KB usage for an empty database. Is there a way to configure initial size of index files? The only method I could think of was to set 'direct' method, create dataset, close it, set method to 'mapped' and open dataset again. But it prints a warning "System file mode already determined - setting it has no effect", and yes, the second setting does not seem to have any effect. Kind regards, Mikhail
