Clusters are sets of records grouped by a mean. Any mean you want to assign. You can use a Cluster like a Table of the Relational DBMS world, namely to group records of the same type. Or you could want to group records by different logics.

There are two kinds of clusters: Physical and In-memory .The first one is persistent, the second one is volatile.

{{ cluster.id }} {{ cluster.name }} {{ cluster.type }} {{ cluster.records }} {{ cluster.size }} {{ cluster.filled }} {{ cluster.maxSize }} {{ cluster.files }}

Data segments are the segments that contain data pointed by Clusters.
