PPL Language Reference
Overview
This is a comprehensive reference for the Piped Processing Language (PPL) used by OpenSearch. PPL queries follow a pipe-delimited syntax starting with source=<index> and chaining commands with |. This reference covers all commands, functions, API endpoints, and usage patterns needed to construct observability queries against trace and log indices.
