A method includes receiving a user-defined extension configured to operate on data from a content database and comprising code expressed in a first programming language, the user-defined extension comprising at least one unresolved object and a function calling the at least one unresolved object. On a first pass through the user-defined extension code, each respective unresolved object is bound to a respective placeholder object such that the function calls each respective placeholder object and each respective placeholder object is mapped to the respective unresolved object, and delaying evaluation of the user-defined extension code until a second pass through the user-defined extension code. On the second pass, machine code corresponding to a compiled version of the user-defined extension is obtained by sequentially obtaining machine code for each respective unresolved object as each respective placeholder is called in the function. A related system and non-transitory computer-readable medium are also provided.

Extensibility in a database system

A method for generating code for queries in a database system includes obtaining a user query in a first programming language, the user query comprising at least one query parameter for selecting data from a content database. The method includes obtaining machine code corresponding to a compiled version of the user query. Obtaining the machine code includes generating code in a second programming language corresponding to a compiled version of the user query, generating byte code defining a plurality of functions corresponding to a compiled version of the code in the second programming language, and obtaining the machine code corresponding to the compiled version of the user query based on the byte code. The method further comprises executing the machine code using the at least one query parameter, thereby returning a result satisfying the at least one query parameter. A related non-transitory computer-readable medium and system are also provided.
