Ingest Attachment Processor Pluginedit
The ingest attachment plugin lets Elasticsearch extract file attachments in common formats (such as PPT, XLS, and PDF) by using the Apache text extraction library Tika.
You can use the ingest attachment plugin as a replacement for the mapper attachment plugin.
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.
Installationedit
Version 8.0.0 of the Elastic Stack has not yet been released.
Removaledit
The plugin can be removed with the following command:
sudo bin/elasticsearch-plugin remove ingest-attachment
The node must be stopped before removing the plugin.
