The default block size for the solidDB database file is 16 KB. The block size is defined in multiples of 4 KB. The minimum block size is 4 KB and the maximum is 64 KB.

The maximum database size is also controlled by the block size. The maximum database size is (2^32-1)*(blocksize). Therefore, with the default 16KB block size, the maximum database size is 64 TB - 16KB.

The block size is set with the parameter Indexfile.BlockSize. If you want solidDB to create a database with a different block size, you must set the Indexfile.BlockSize value before creating a database. If you have an existing database, remember to move the old database (.db) and log files (.log) to another directory; the next time you start solidDB, a new database is created.

To modify the constant value for the new database, add the following lines in the solid.ini file, providing the size in bytes:

The unit of size is 1 byte (as in all size-related parameters). You can also use the unit symbols of K for KB and M for MB.

After you save the file and start solidDB, solidDB creates a database with the size specified in the new constant value in solid.ini file.

Similarly, you can also modify the Indexfile.FileSpec parameter to define the following values:

You can also use the Indexfile.FileSpec parameter to divide the database file into multiple files and onto multiple disks. Multiple database files are useful if you require a large physical database.

For details on configuring the database file locations and sizes with the Indexfile.FileSpec parameter, see Managing database files and caching (IndexFile section).
