/**
* {@link Log} storage level configuration values which control how logs are stored on disk or in memory.
*
* Storage levels represent the method used to store the individual {@link Segment segments} that make up a
* {@link Log}. When configuring a {@link Storage} module, the storage can be configured to write
* {@link io.atomix.copycat.server.storage.entry.Entry entries} to disk, memory, or memory-mapped files using the
* values provided by this enum. The {@code StorageLevel} configuration dictates the type of
* {@link io.atomix.catalyst.buffer.Buffer} to which to write entries. See the specific storage levels for more
* information.
