Container framework for user-defined functions

A method comprising:

• receiving, by a distributed database system installed on a cloud computing platform, a query written in a primary query language, wherein the query calls a user-defined function;
• assigning one or more primary segment hosts on the cloud computing platform to process one or more portions of the query written in the primary query language;
• assigning one or more first containers to process the call to the user-defined function in the query;
• providing, by the one or more primary segment hosts to the one or more first containers assigned to process the call to the user-defined function, the user-defined function and one or more arguments in the calf to the user-defined function;
• executing, by the one or more first containers assigned to process the call to the user defined function, the user-defined function using the arguments to the call in the user-defined function;
• receiving, by the one or more primary segment hosts, an initial result of the call to the user-defined function computed by the one or more first containers;
• computing, by the one or more primary segment hosts, a final result of the query using the initial result of the call to the user-defined function;
• and
• providing the final result of the query in response to receiving the query.

One or more non-transitory computer storage media storing instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• receiving, by a distributed database system installed on a cloud computing platform, a query written in a primary query language, wherein the query calls a user-defined function;
• assigning one or more primary segment hosts on the cloud computing platform to process one or more portions of the query written in the primary query language;
• assigning one or more first containers to process the call to the user-defined function in the query;
• providing, by the one or more primary segment hosts to the one or more first containers assigned to process the call to the user-defined function, the user-defined function and one or more arguments in the call to the user-defined function;
• executing, by the one or more first containers assigned to process the call to the user defined function, the user-defined function using the arguments to the call in the user-defined function;
• receiving, by the one or more primary segment hosts, an initial result of the call to the user-defined function computed by the one or more first containers;
• computing, by the one or more primary segment hosts, a final result of the query using the initial result of the call to the user-defined function;
• and
• providing the final result of the query m response to receiving the query.
