    EventQL is a open-source massively parallel database that supports SQL queries on large datasets.

    EventQL is the open source version of Google's BigQuery system. One explicitly stated design goal is that EventQL is able to scale to 10,000 servers or more and to be able to process hundreds of terrabytes of data and trillions of events in seconds.

    EventQL's location-aware optimizer automatically restructures a query plan to improve data locality.[1]

    Features[edit]

    • Streaming insert and update operations
    • SQL and JavaScript MapReduce Queries
    • Tables and queries are transparently split into partitions and distributed over many servers.
    • Supports Nested Records (ARRAY and OBJECT column types)
    • Open-source C++11 codebase

    Dependencies[edit]

    EventQL relies on the Apache ZooKeeper cluster coordination service. [2]
