  • DISTRIBUTED QUERY PLAN GENERATION
    Publication number: 20230376485
    Abstract: A method, a system, and a computer program product for generating an executable query plan. A query requiring access to data stored in a database system is received. Based on the received query, a query execution plan having a plurality of query execution pipelines is generated. Each query execution pipeline in the plurality of query execution pipelines is configured to execute a plurality of operations in a predetermined order associated with each query execution pipeline. The generated query execution plan is fragmented into a plurality of fragments. Each fragment has one or more query execution pipelines in the plurality of query execution pipelines. Each fragment of the generated query execution plan is transmitted to one or more execution locations in a plurality of execution locations for execution. Each fragment of the generated query execution plan is executed at one or more execution locations. One or more results of executions are combined to generate a response to the received query.
