| Fact | HSQLDB | WiredTiger |
|---|---|---|
| Capacity | Official limits include disk tables up to 8 TB, text tables up to 256 GB and individual CLOB/BLOB storage up to 64 TB. | The overview states support for petabyte tables, records up to 4 GB, and 64-bit record numbers. |
| Concurrency | The engine is multithreaded and offers lock-based, MVCC and hybrid transaction-control models. | Its optimistic concurrency control avoids a centralized lock manager, and transactional operations in one thread do not block operations in other threads. |
| Maker | HSQLDB is developed and published by The HSQL Development Group, formed in 2001. | WiredTiger is developed and maintained by MongoDB, Inc., where it is the principal database storage engine. |
| Support | Support options include a help forum, a user mailing list, bug and feature request trackers, paid SupportWare, and professional commercial support. | The project directs users to its user group and [email protected], and says to contact MongoDB for technical support. |
