# Queryable & Lightweight ### **Keep Nodes Lightweight while Queryable** We retain the standard Substrate node which is lightweight and easily maintainable. For querying transactions and event logs, we offer an indexer node that is open-sourced and anyone can run a copy of it like a full-node. For convenience, we’d offer one docker image to run both nodes, but it is important that there’s a choice for people who want to run one or another for their purposes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://wiki.acala.network/learn/acala-evm/acala-evm-composable-defi-stack/queryable-and-lightweight.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
