You can reduce memory usage in Airbyte by setting the

--event-buffer-size

option. This option was introduced in version 0.1.73 of the base-normalization module (source: [Basic Normalization CHANGELOG](https://docs.airbyte.com/understanding-airbyte/basic-normalization#changelog)). However, the provided extracts do not contain specific instructions on how to set this option. For more information on troubleshooting and optimizing Airbyte, you can refer to the [troubleshooting guide](https://docs.airbyte.com/troubleshooting).
