Hire Presto/Trino Experts | Nearshore Software Development

Presto (and its fork, Trino) is a high-performance, distributed SQL query engine for big data. Its key feature is the ability to query data where it lives, including in Hadoop, S3, Cassandra, and relational databases, without moving it. You need an expert who can leverage Presto/Trino to build a powerful, federated analytics platform. Our vetting process, powered by Axiom Cortex™, finds engineers who are masters of distributed SQL. We test their ability to write complex federated queries, tune performance, and manage a large-scale Presto/Trino cluster.

Are your data silos preventing you from getting a complete view of your data?

The Problem

Your data is spread across multiple systems—a data lake in S3, a NoSQL database, and a relational data warehouse. Getting a unified view requires complex and slow ETL jobs.

The TeamStation AI Solution

We vet for engineers who are experts in federated queries. They must demonstrate the ability to use Presto/Trino to write a single SQL query that joins data from multiple, disparate data sources, providing a real-time, unified view of your data.

Proof: Federated Queries Across Data Silos

Are your ad-hoc queries on your data lake slow and inefficient?

The Problem

Querying large datasets in a data lake with traditional tools can be incredibly slow, preventing your analysts and data scientists from exploring data at the speed of thought.

The TeamStation AI Solution

Our experts are proficient in Presto/Trino performance tuning. They are vetted on their ability to optimize query execution and to configure a Presto/Trino cluster for high-performance, interactive queries on massive datasets.

Core Competencies We Validate

Presto/Trino architecture and core concepts

Connector configuration for various data sources

Federated query writing and optimization

Performance tuning and resource management

Deployment and management of a Presto/Trino cluster

Our Technical Analysis

The Presto/Trino evaluation focuses on large-scale, federated data analytics. Candidates are required to write a complex SQL query that joins data from multiple different data sources (e.g., S3, MySQL, MongoDB), demonstrating their understanding of the federated query model. A critical assessment is their ability to diagnose and fix a slow-running query by analyzing the query plan and tuning the cluster configuration. We also test their knowledge of the various connectors and how to configure them. Finally, we assess their experience in deploying and managing a Presto/Trino cluster in a production environment.
