Python on OpenSearch: Bringing Native Python Scripting to Search and An...
summary
Plugin runs Python inside OpenSearch via GraalVM polyglot context, executing scripts with document fields and query parameters bound directly from Java; demos show regex and JSON extraction from logs, e‑commerce ranking using bundled NumPy, and live LLM HTTP calls at query time. Implementation uses AST parsing, a static semantic analyzer, hard timeouts and fresh contexts per execution. Current trade-offs: trusted sandbox for NumPy and 1.4–2.2× slower than Painless, plus third‑party libs require rebuilding the plugin; roadmap targets pooling, security policies, and optimizations.
