-## What is Langfuse?
+## Overview

-Langfuse is an open source observability & analytics solution for LLM-based applications. It is mostly geared towards production usage but some users also use it for local development of their LLM applications.
+### Develop

-Langfuse is focused on applications built on top of LLMs. Many new abstractions and common best practices evolved recently, e.g. agents, chained prompts, embedding-based retrieval, LLM access to REPLs & APIs. These make applications more powerful but also unpredictable for developers as they cannot fully anticipate how changes impact the quality, cost and overall latency of their application. Thus Langfuse helps to monitor and debug these applications.
+- **Observability:** Instrument your app and start ingesting traces to Langfuse ([Quickstart](https://langfuse.com/docs/get-started), [Integrations](https://langfuse.com/docs/integrations) [Tracing](https://langfuse.com/docs/tracing))
+- **Langfuse UI:** Inspect and debug complex logs ([Demo](https://langfuse.com/docs/demo), [Tracing](https://langfuse.com/docs/tracing))
+- **Prompts:** Manage, version and deploy prompts from within Langfuse ([Prompt Management](https://langfuse.com/docs/prompts))

-**Demo (2 min)**
+### Monitor
+
+- **Analytics:** Track metrics (cost, latency, quality) and gain insights from dashboards & data exports ([Analytics](https://langfuse.com/docs/analytics))
+- **Evals:** Collect and calculate scores for your LLM completions ([Scores & Evaluations](https://langfuse.com/docs/scores))
+  - Run model-based evaluations ([Model-based evaluations](https://langfuse.com/docs/scores/model-based-evals))
+  - Collect user feedback ([User Feedback](https://langfuse.com/docs/scores/user-feedback))
+  - Manually score observations in Langfuse ([Manual Scores](https://langfuse.com/docs/scores/manually))
+
+### Test
+
+- **Experiments:** Track and test app behaviour before deploying a new version
+  - Datasets let you test expected in and output pairs and benchmark performance before deployiong ([Datasets](https://langfuse.com/docs/datasets))
+  - Track versions and releases in your application ([Experimentation](https://langfuse.com/docs/experimentation), [Prompt Management](https://langfuse.com/docs/prompts))

+### Ingesting Data · Instrumenting Your Application

-#### Langchain applications
+Note: We recommend using our fully async, typed [SDKs](https://langfuse.com/docs/sdk) that allow you to instrument any LLM application with any underlying model. They are available in [Python](https://langfuse.com/docs/sdk/python) & [JS/TS](https://langfuse.com/docs/sdk/typescript). The SDKs will always be the most fully featured and stable way to ingest data into Langfuse.

-The Langfuse callback handler automatically instruments Langchain applications. Currently available for Python and JS/TS.
+You may want to use another integration to get started quickly or implement a use case that we do not yet support. However, we recommend to migrate to the Langfuse SDKs over time to ensure performance and stability.

-**Python**
+See our the [→ Quickstart](https://langfuse.com/docs/get-started) to get started in integrating Langfuse.

-```shell
-pip install langfuse

-#### Add scores/evaluations to traces (optional)
+### Support and feedback

-Quality/evaluation of traces is tracked via scores ([docs](https://langfuse.com/docs/scores)). Scores are related to traces and optionally to observations. Scores can be added via:
+In order of preference the best way to communicate with us:

- **Backend SDKs** (see docs above): `{trace, event, span, generation}.score()`
- **API** (see docs below): `POST /api/public/scores`
- **Client-side using Web SDK**, e.g. to capture user feedback or other user-based quality metrics:
-
-  ```sh
-  npm install langfuse
-  ```
-
-  ```ts
-  // Client-side (browser)
-
-  import { LangfuseWeb } from "langfuse";
-
-  const langfuseWeb = new LangfuseWeb({
-    publicKey: process.env.LANGFUSE_PUBLIC_KEY,
-  });
-
-  // frontend handler (example: React)
-  export function UserFeedbackComponent(props: { traceId: string }) {
-    const handleUserFeedback = async (value: number) => {
-      await langfuseWeb.score({

+ * object mode, directly streaming database entity objects.
+ *
+ * Note: Due to Prisma's lack of direct streaming support, this class implements a chunk-based approach
+ * rather than true database streaming. It fetches data in paginated batches determined by the pageSize.
+ * GitHub issue: https://github.com/prisma/prisma/issues/5055
+ *
+ * @param prisma - The PrismaClient instance for database queries.
+ * @param rawSqlQuery - A Prisma.Sql object representing the base SQL query, excluding OFFSET and LIMIT.
+ * @param pageSize - Number of records per batch, defining the chunk size.
+ *
+ * The class extends Node.js's Readable stream, using async iteration and Prisma's pagination for scalable
+ * data processing. It's suitable for applications requiring large dataset processing with a low memory footprint.
