Abstract: A method includes receiving an initial pipeline including a sequence of commands for execution on a computing system, and obtaining, for each command in the sequence of commands, semantic information. The sequence of commands includes a command with incomplete semantic information. The method further includes generating an abstract semantic tree (AST) with the semantic information and a placeholder for the incomplete semantic information, and manipulating the AST to generate a revised AST. The revised AST corresponds to a revised pipeline that reduces an execution time on the computing system. The method further includes executing the revised pipeline.

Abstract: The disclosed embodiments include a method performed by a data intake and query system. The method includes populating each metric including a measure value, cataloging metadata in an in-memory metrics catalog, where the metadata is related to the metrics. The method further includes receiving a search query including search criteria, evaluating the search query by applying the search criteria to the metadata of the metrics catalog to obtain results that satisfy the search criteria, and causing display, on a display device, of the results or data indicative of the results.
