Configuration: Storage Engines

RavenDB supports two storage engines and each database can be created with a different one:

• (Default) ESE (Extensible Storage Engine aka Esent) - Microsoft storage engine available in Windows. More info here.
• Voron - custom made managed storage engine created by Hibernating Rhinos.

Limitations

• key size must be less than 2048 bytes in Unicode

Limitations

• key size must be less than 2024 bytes in UTF8
• no support for DTC transactions

Requirements

• disk must handle UNBUFFERED_IO/WRITE_THROUGH properly
• .NET 4.5 or higher
• Hotfix for Windows 7 and Windows Server 2008 R2

In order to change a storage engine in the Studio, while you are creating a database, go to Advanced Settings and change Storage Engine according to your needs.
