Presto: SQL-on-Anything
Deploy Anywhere, Query Anything
Why Presto?
Community-driven open source project
High performance ANSI SQL engine• New Cost-Based Query Optimizer• Proven scalability• High concurrency
Separation of compute and storage• Scale storage and compute
independently• No ETL or data integration
necessary to get to insights• SQL-on-anything
No vendor lock-in• No Hadoop distro vendor lock-in• No storage engine vendor lock-in• No cloud vendor lock-in
Enterprise edition

Founded by Presto committers:● Over 4 years of contributions to Presto● Presto distro for on-prem and cloud env● Supporting large customers in production● Enterprise subscription add-ons (ODBC,
Ranger, Sentry, Oracle, Teradata, K8S)
Notable features contributed:● ANSI SQL syntax enhancements● Execution engine improvements● Security integrations● Spill to disk● Cost-Based Optimizer

Built for PerformanceQuery Execution Engine:
● MPP-style pipelined in-memory execution● Columnar and vectorized data processing● Runtime query bytecode compilation● Memory efficient data structures● Multi-threaded multi-core execution● Optimized readers for columnar formats (ORC and Parquet)● Predicate and column projection pushdown● Now also Cost-Based Optimizer
