Storage: Directory Structure

RavenDB keeps all data in a location specified in DataDir setting. The structure of RavenDB data directories are as follows:

• {DataDir}
  • Databases
    • <database-name>
      • Confguration
        • Journals
        • Temp
      • Indexes
        • <index-name>
          • Journals
          • Temp
        • ...more indexes...
      • Journals
      • Temp
    • ...more databases...
  • System
    • Journals
    • Temp

The main directory has a Databases folder, which contains subdirectories per each database, and a System folder where server-wide data are stored (e.g. database records, cluster data).

The database is composed of such data items as documents, indexes, and configuration. Each of them is a separate Voron storage environment. The data is persisted in a Raven.voron file and .journal files which are located in the Journals directory. In addition, temporary files are put into the Temp folder.
