A cache of data maintained by the nodes in an Eon Mode database to limit reads from communal storage. Retrieving data from communal storage often has high latency and potentially limited bandwidth, especially in cloud environments. Each node in the database caches the data it reads from and writes to the communal storage. When processing a query, they first check this local cache for the data they need. If the data is cached locally, the nodes use the cached version instead of retrieving the data from communal storage.
