You can use the ingest attachment plugin as a replacement for the mapper attachment plugin.

Ingest Attachment: Allow to prevent base64 conversions by using raw bytes (#16601) CBOR is natively supported in Elasticsearch and allows for byte arrays. This means, that by using CBOR the user can prevent base64 conversions for the data being sent back and forth. This PR adds support to extract data from a byte array in addition to a string. This also required to add a ByteArrayValueSource class.

The source field must be a base64 encoded binary. If you do not want to incur
the overhead of converting back and forth between base64, you can use the CBOR
format instead of JSON and specify the field as a bytes array instead of a string
representation. The processor will skip the base64 decoding then.

NOTE: Extracting contents from binary data is a resource intensive operation and
consumes a lot of resources. It is highly recommended to run pipelines
using this processor in a dedicated ingest node.
