BYOC Components

This topic introduces the set of system components you need to understand in order to utilize the Zilliz Cloud Bring Your Own Cloud (BYOC) solution effectively.

Proxy: Your gateway to Zilliz Cloud​

The Proxy serves as the access layer of Zilliz Cloud, acting as the primary endpoint for client interactions. It's a stateless component that performs crucial functions such as:

  • Validating client requests.

  • Reducing result sets for efficiency.

  • Aggregating and post-processing results in Zilliz Cloud's Massively Parallel Processing (MPP) architecture.

  • Providing a unified service address through load balancers like Nginx and Kubernetes Ingress.

Coordinator: The brain of the operation​

The Coordinator is akin to the central nervous system of Zilliz Cloud, orchestrating various tasks across worker nodes. It's divided into four types, each with a specific role:

  • Query Coordinator (Query Coord): Handles query node topology, load balancing, and segment transitions.

  • Data Coordinator (Data Coord): Oversees data node topology, metadata maintenance, and triggers background data operations.

  • Index Coordinator (Index Coord): Manages index node topology, index building, and index metadata.

Query node: The data retriever​

The Query Node is crucial for handling incremental log data. It transforms these logs into growing segments and executes hybrid searches combining vector and scalar data.

Data node: The data processor​

The Data Node processes mutation requests and converts log data into snapshots for storage in object storage, ensuring efficient data handling.

Index node: The index builder​

The Index Node specializes in building indexes. It's a flexible component that can operate in a non-memory resident mode, suitable for serverless frameworks.
