    Continuous Queries

    Continuous queries are similar to regular database queries with a few key differences as they run on data streams.

    Difference from regular database queries

    Database Queries Continuous Queries
    Invoked manually Always running
    Results available on query completion Results are always available
    Aggregations for a fixed time interval Aggregations for sliding windows and session windows

    How to define continuous queries

    Upsolver's user interface acts as a query builder directly on raw file formats like JSON and CSV.

    How to retrieve the results

    There are 2 options:

    • Query API to get the most current query results.
    • Incrementally sending the query results to an Output.

    Retroactive queries with Amazon S3

    Upsolver curates all incoming events on Amazon S3 so continuous queries could start running retroactively, saving the time spent waiting for data to accumulate.
