Any metadata changes on the source object version, such as metadata updates via PutObjectTagging, PutObjectRetention, PutObjectLegalHold and COPY api are replicated in a similar manner to target version, with the `X-Amz-Replication-Status` again cycling through the same states.

```Python hl_lines="18-20"

```

For the **next request**, as we will reset that context variable again in the `async` dependency `reset_db_state()` and then create a new connection in the `get_db()` dependency, that new request will have its own database state (connection, transactions, etc).

!!! tip
    Every time you install a new package with `pip` under that environment, activate the environment again.

    This makes sure that if you use a terminal program installed by that package, you use the one from your local environment and not any other that could be installed globally.
