THEN Implement async versions of OpensearchVectorClient and OpensearchVectorStore by inheriting from the synchronous classes and monkeypatching the client creation to use AsyncOpenSearch from opensearch-py. Override query methods with async/await while keeping the same logic.

class AsyncOpensearchVectorClient(OpensearchVectorClient, AsyncOpensearchVectorStore):
    def __init__(self, ...):
        # Use AsyncOpenSearch client from opensearch-py
        ...
    async def aquery(self, query):
        # identical logic but with async/await
        ...
