+=== Document ID Generation
+
+This aws-s3 input feature prevents the duplication of events in Elasticsearch by
+generating a custom document `_id` for each event, rather than relying on
+Elasticsearch to automatically generate one. Each document in an Elasticsearch
+index must have a unique `_id`, and {beatname_uc} uses this property to avoid
+ingesting duplicate events.
+
+The custom `_id` is based on several pieces of information from the S3 object:
+the Last-Modified timestamp, the bucket ARN, the object key, and the byte
+offset of the data in the event.
+
+Duplicate prevention is particularly useful in scenarios where {beatname_uc}
+needs to retry an operation. {beatname_uc} guarantees at-least-once delivery,
+meaning it will retry any failed or incomplete operations. These retries may be
+triggered by issues with the host, `{beatname_uc}`, network connectivity, or
+services such as Elasticsearch, SQS, or S3.
+
+[float]
+==== Limitations of `_id`-Based Deduplication
+
+There are some limitations to consider when using `_id`-based deduplication in
+Elasticsearch:
+
+* Deduplication works only within a single index. The same `_id` can exist in
+  different indices, which is important if you're using data streams or index
+  aliases. When the backing index rolls over, a duplicate may be ingested.
+
+* Indexing operations in Elasticsearch may take longer when an `_id` is
+  specified. Elasticsearch needs to check if the ID already exists before
+  writing, which can increase the time required for indexing.
+
+[float]
+==== Disabling Duplicate Prevention
+
+If you want to disable the `_id`-based deduplication, you can remove the
+document `_id` using the <<drop-fields,`drop_fields`>> processor in
+{beatname_uc}.
