What is the biggest known HSQLDB database?
The current (2.0) size limit of an HSQLDB database is 16GB (by default) for all CACHED tables and 2GB for each TEXT table. If you use large MEMORY tables, memory is only limited by the allocated JVM memory, which can be several GB on modern machines and 64bit operating systems. Extensive tests have been made with the latest versions using the TestCacheSize and other test programs inserting millions of rows and resulting in data files of up to 16 GB and larger LOB sizes.
