Using Eon Mode

You can operate your Vertica database in Eon Mode instead of in Enterprise Mode. The two modes differ primarily in how they store data:

  • Eon Mode databases use communal storage for their data.
  • Enterprise Mode databases store data locally in the file system of nodes that make up the database.

These different storage methods lead to a number of important differences between the two modes. In Enterprise Mode, each database node stores a portion of the data and performs a portion of the computation. In Eon Mode, computational processes are separated from a communal (shared) storage layer, which enables rapid scaling of computational resources as demand changes.

For more on how these two modes compare, see Vertica Architecture: Eon Versus Enterprise Mode.
