Presto/Trino Architecture Explained

In this section, we will delve into the intricacies of the Presto/Trino architecture, providing a comprehensive understanding of how this powerful SQL query engine operates. By exploring its various components and their interplay, data engineers can gain valuable insights into how Presto/Trino processes queries and delivers lightning-fast results.

Components of Presto/Trino Architecture

The architecture of Presto/Trino is based on a distributed and scalable approach, enabling it to handle massive amounts of data efficiently. The key components of the Presto/Trino architecture include:

  1. Coordinator: The Coordinator node acts as the brain of the system, receiving queries from users and orchestrating their execution across the worker nodes. It analyzes and optimizes query plans to ensure efficient data retrieval and processing.
  2. Worker: Worker nodes are responsible for executing tasks assigned by the Coordinator. They perform query scanning, filtering, and aggregating operations on data stored in distributed data sources. Each worker node operates independently, storing data in worker memory during query execution.
  3. Connector: Connectors provide the necessary interfaces for Presto/Trino to interact with various data sources, such as databases, data lakes, and external storage systems. Each connector translates Presto/Trino’s SQL queries into native queries specific to the data source, enabling seamless data retrieval and integration.
  4. Catalog: The Catalog is a metadata management component that stores and organizes information about the available data sources and the tables within them. It enables users to discover and access the data stored in different connectors through a unified interface.
  5. Scheduler: The Scheduler assigns tasks to worker nodes, ensuring optimal resource allocation and load balancing. It considers factors such as data locality, worker availability, and query priorities to efficiently distribute query processing across the cluster.

How Presto/Trino Architecture Works

Presto/Trino follows a three-step process to execute queries:

  1. Query Parsing and Analysis: When a query is submitted, the Coordinator parses the SQL statement and performs semantic analysis to understand the query’s intent. It determines the data sources involved, identifies applicable connectors, and validates the query syntax and structure.
  2. Query Optimization: After parsing, the Coordinator optimizes the query plan by considering data statistics, available resources, and query cost. It applies various optimization techniques, such as predicate pushdown, join reordering, and partial aggregation, to generate an efficient query execution plan.
  3. Query Execution: Once the query plan is optimized, the Coordinator distributes the query tasks to the worker nodes. Each worker retrieves data from the relevant connectors, performs the necessary operations, and returns the intermediate results to the Coordinator. The Coordinator then consolidates and processes the intermediate results to generate the final query output.

By dividing the query execution process into these distinct steps, Presto/Trino achieves high performance and scalability. The distributed architecture ensures parallel processing and efficient resource utilization, enabling data engineers to query vast amounts of data with remarkable speed.
