Decision brief
DBreeze is an ACID-compliant C# .NET database management system that supports key-value storage and offers advanced search features alongside vector layer capabilities.
Good fit when
- When developing applications in the C# .NET environment requiring robust, transactional (ACID) support.
- For scenarios where both efficient text and semantic searches need to be integrated within a single database solution.
Avoid when
- If the project demands real-time scalability and distribution capabilities beyond what an embedded database can offer
- In cases where Python, Java, or other non-.NET languages are preferred or required for development.
- Pricing:
- freemium - The BSD-2-Clause license under which DBreeze is released allows free usage, but there may be options for paid support or enhanced services not detailed here.

Key features:
- Embedded .NET family assembly, platform independent and without references to other libraries.
- Multi-threaded, ACID compliant, with a solution for deadlocks resolving/elimination, parallel reads and synchronized writes/reads.
- No fixed scheme for table names (construction and access on the fly).
- Tables can reside in mixed locations: different folders, hard drives, memory, in-memory with disk persistence.
- Liana-Trie indexing technology. Database indexes (keys) never need to be defragmented. Speed of insert/update/remove operations doesn't change during the time.
- Ability to access Key/Value pair of a table by physical link, that can economize time for joining necessary data structures.
- No limits for database size (except "long" size for each table and physical resources constraints).
- Low memory and phys
