Cluster Monitor

The cluster monitor lets you scale out MemCP over multiple nodes. Here is what you can achieve:

• Multiple users: each user has his own database
• One big user: Big tables are spread over multiple nodes
• A mixture of both variants

Each database and each shard (the piece where a part of a table's data is stored) can be placed either:

• COLD: only in storage backend
• SHARED: read-only on multiple nodes (e.g. the access table)
• WRITE: exclusively on one node

Cluster monitors can coordinate all kinds of storage:

• File System

• S3 Buckets
• Ceph/Rados
