**FastAPI** gives you the following:

### Based on open standards { #based-on-open-standards }

  /** Returns the platform preferred implementation of a map based on a hash table. */
  static <K extends @Nullable Object, V extends @Nullable Object>
      Map<K, V> newHashMapWithExpectedSize(int expectedSize) {
    return Maps.newHashMapWithExpectedSize(expectedSize);
  }

  /**
   * Returns the platform preferred implementation of an insertion ordered map based on a hash
   * table.
   */

**NOTE**: When configuring multiple OpenID based authentication providers on a MinIO cluster, any number of Role Policy based providers may be configured, and at most one JWT Claim based provider may be configured.

<details><summary>Example 1: Two role policy providers</summary>

Sample environment variables:

```

import jakarta.annotation.Resource;

/**
 * <p>
 * {@link DefaultResponseProcessor} is a default implementation of {@link ResponseProcessor}.
 * It processes the response data based on the HTTP status code and configured transformer.
 * </p>
 *
 * <p>
 * It handles successful responses by transforming the data using a {@link Transformer}

            // Set event type based on message type
            WitnessEventType eventType = convertMessageTypeToEventType(message.getType());
            notification.setEventType(eventType);
            notification.setTimestamp(message.getTimestamp());

            // Set resource name based on message content
            if (message.getResourceName() != null) {

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.
