Operator Acceleration and Materialized View

The environment planned in this document for operator acceleration and materialized view consists of four servers for example, which are one management node and three compute nodes. The coupled storage and compute network is used. In the following, we will be using HDFS as the storage node for illustration:

• The management node is server1 for managing tasks.
• The compute nodes are agent1, agent2, and agent3, which are used to run OmniOperator and OmniMV query engine services and store datasets.

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

• OmniOperator is installed on the management node and compute nodes to run the big data query service.
• OmniMV is installed on the management node and compute nodes to run the big data query engine service.
