Apache Impala vs Firebolt

Apache Impala is a free, open-source native analytic database for SQL queries on open data and table formats. It targets low-latency, high-concurrency business intelligence and analytics in Hadoop environments and is described as scaling linearly, including for multitenant use. Impala works with HDFS, HBase and Amazon S3, plus Apache Kudu, Apache Iceberg and other listed sources. Supported formats include delimited text, Parquet, Avro, SequenceFile and RCFile, with Snappy, GZIP, Deflate and BZIP codecs. Clients can connect through impala-shell, Hue, JDBC or ODBC. The system reuses Hadoop file formats, metadata, security and resource-management frameworks, and shares metadata and an ODBC driver with Apache Hive. Kudu tables support queries and efficient updates or deletes; Iceberg tables can be registered with the Hive Metastore. Kerberos, Apache Ranger authorization, auditing and encrypted JDBC or ODBC connections are supported. Impala runs on Linux and macOS, supports API use and self-hosted deployment, and is licensed under Apache License 2.0.

Firebolt is an open-source analytical database for engineers, with Postgres-compatible SQL and options for self-managed or managed deployment. It can run as a single binary on a laptop or scale to a cluster of hundreds of nodes in a customer’s cloud. Firebolt is designed for sub-second query latency and high-concurrency analytics, and supports Apache Iceberg and DuckLake using open storage standards. Deployment choices include a single binary, Helm chart, Kubernetes Operator, and managed service. Firebolt Core is free forever for self-hosted use, with no usage limits; it cannot be used to build a hosted SaaS that competes with Firebolt’s managed service. Managed compute is billed per second, with scale-to-zero, automatic start and stop, and autoscaling. Object storage is pass-through at $0.0264 / GB·mo, and the managed service includes $200 free credits. AI capabilities include query and embedding functions, vector search, an MCP Server, and a preview agent. Self-managed availability includes AWS and GCP, with Azure in preview; the managed service is currently AWS-only.
