OmniData

The environment planned in this document for operator pushdown consists of seven servers for example, which are one management node, three compute nodes, and three storage nodes. The decoupled storage-compute network is used. In the following, we will be using Ceph as the storage node for illustration:

• The management node is server1 for managing tasks.
• The compute nodes are agent1, agent2, and agent3, for running the big data query engine service.
• The storage nodes are ceph1, ceph2, and ceph3, for running the OmniData service.

A server can function as a management node, a compute node, and a storage node at the same time. In single-node mode, operations performed on the management node, compute node, or storage node (offload node) mentioned in the following sections are performed on the same node. Figure 1 shows the networking diagram.
