Bundle: Compression

To reduce the cost of I/O operations and reduce the size of the database on a disk, we have introduced the Compression bundle. Compression is only applied to documents, indexes are not compressed. This is because RavenDB is performing a lot of random reads from indexes, whereas with documents we almost always read/write the full content. Note that the compression process is fully transparent for the end-user.

How to enable compression

To activate compression server-wide, just add the Compression to the Raven/ActiveBundles configuration in the global configuration file or set up a new database with compression bundle turned on, using API or the Studio.

More on how to create a database with compression enabled using the Studio here.

store
	.DatabaseCommands
	.GlobalAdmin
	.CreateDatabase(
		new DatabaseDocument
			{
				Id = "CompressedDB",
				// Other configuration options omitted for simplicity
				Settings =
					{
						// ...
						{ "Raven/ActiveBundles", "Compression" }
					}
			});

The above example demonstrates how to create a new database called CompressedDB with the Compression bundle enabled.
