10 Best ETL & Data Pipelines Tools in 2026

Kafka moves data at massive scale. When millions of events per second need to flow between systems reliably, Kafka provides the highway. Producers publish messages, consumers read them, and nothing gets lost even when systems crash. Topics organize streams of data with configurable retention. Consumer groups enable parallel processing. The distributed architecture means no single point of failure and virtually unlimited throughput. Kafka has become the backbone of modern data architectures. Real-time analytics, event-driven microservices, change data capture—any use case involving high-volume streaming likely runs on Kafka.

Steampipe is an open-source data-access layer that allows users to query cloud APIs, code, and other data sources using standard SQL. It eliminates the need for complex ETL processes by providing a 'Zero-ETL' approach, treating live cloud configurations and other data as a dynamic database. This enables developers, security professionals, and operations teams to gain real-time insights without syncing or relying on outdated data. The platform leverages a vast library of plugins (over 500) to connect to various services like AWS, Azure, GCP, and many others, organizing their metadata into discoverable SQL tables. This unified SQL interface simplifies tasks such as compliance auditing, security posture assessment, cost optimization, and operational troubleshooting. Steampipe can be used as a CLI tool, or integrated as a PostgreSQL FDW or SQLite extension, making it a versatile tool for anyone needing to analyze and manage their cloud infrastructure and API data efficiently.

DuckDB is an analytics database that runs in-process. Query data with SQL wherever your application runs—the analytical performance of columnar databases without separate infrastructure.
