## 3. Activate ILM versioning features

This will only work with a versioned bucket, take a look at [Bucket Versioning Guide](https://docs.min.io/community/minio-object-store/administration/object-management/object-versioning.html) for more understanding.

### 3.1 Automatic removal of non current objects versions

import org.junit.jupiter.api.Test

class ConnectionPoolTest {
  private val routePlanner = FakeRoutePlanner()
  private val factory = routePlanner.factory
  private val peer = MockHttp2Peer()

  /** The fake task runner prevents the cleanup runnable from being started.  */
  private val addressA = factory.newAddress("a")
  private val routeA1 = factory.newRoute(addressA)
  private val addressB = factory.newAddress("b")

    fullBuffer.read(bytesOut, lastFrame.start + length)
    outFrames.add(OutFrame(lastFrame.sequence, lastFrame.start, true))
    return writer
  }

  fun takeFrame(): InFrame = inFrames.take()

  fun play() {
    check(serverSocket == null)
    serverSocket = ServerSocket()
    serverSocket!!.reuseAddress = false
    serverSocket!!.bind(InetSocketAddress("localhost", 0), 1)

### 2. Install boto3

Install `aws-sdk-python` from AWS SDK for Python official docs [here](https://aws.amazon.com/sdk-for-python/)

### 3. Example

                    sha1ChecksumObserver = addChecksumObserver(wagon, "SHA-1");

                    // reset the retry flag.
                    retry = false;

                    // This should take care of creating destination directory now on
                    if (destination.exists() && !force) {
                        try {

			return
		}
		if sameTarget && bucket == clnt.Bucket {
			writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBucketRemoteIdenticalToSource), r.URL)
			return
		}

		reader := bytes.NewReader(buf)
		// fake a PutObject and RemoveObject call to validate permissions
		c := &minio.Core{Client: clnt.Client}
		putOpts := minio.PutObjectOptions{
			Internal: minio.AdvancedPutOptions{
				SourceVersionID:          mustGetUUID(),

No, an upgrade should not cause any downtime. However, on the first startup -
since MinIO will attempt to migrate any existing IAM data - the boot process may
take slightly longer, but may not be visibly noticeable. Once the migration has

The same models are shared among requests, so, it's not one model per request, or one per user or something similar.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.
