Abstract

A system for code development and execution includes a client interface and a client processor. The client interface is configured to receive user code for execution and receive an indication of a server that will perform the execution. The client processor is configured to parse the user code to identify one or more data items referred to during the execution. The client processor is also configured to provide the server with an inquiry for metadata regarding the one or more data items, receive the metadata regarding the one or more data items, determine a logical plan based at least in part on the metadata regarding the one or more data items; and provide the logical plan to the server for execution.
