What is Apache Drill?

Apache Drill is an open source distributed SQL query engine designed to provide low-latency query capabilities for large-scale, complex data sets. Its most notable feature is the ability to directly query and analyze massive amounts of semi-structured, unstructured, and structured data without having to define a fixed schema in advance. This makes Apache Drill an ideal choice for processing data lakes and big data analysis because it can flexibly adapt to a variety of data formats, including JSON, Avro, Parquet, CSV, etc., and can query across multiple data sources.

What are the main features of Apache Drill?

Apache Drill has several key features that make it unique in the world of big data querying:

• Schema-less queries: Drill is able to read and query data without a predefined schema, which greatly simplifies the data ingestion and query process.
• Dynamic Data Discovery: Drill can automatically detect the structure of data, the so-called "schema discovery", which means that users can query data directly without manually creating table definitions.
• Distributed processingDrill is designed to support distributed environments and can process data in parallel using multiple nodes in a cluster.
