By default, Elasticsearch accepts a bulk request with up to 100MB, a bulk request greater than 100MB fails with

ElasticsearchStatusException[Unable to parse response body]; nested: ResponseException[method [POST], host [http://elasticsearch:9200], URI [/_bulk], status line [HTTP/1.1 413 Request Entity Too Large] ];

Once failed with such an exception, the importer simply retries the bulk request forever.

Steps to reproduce:

Submit a bulk request greater than 100MB.

Actual result:

• The importer retries the bulk request forever.
• The importer gets stuck at that point.

Expected result:

• One option would be to do bookkeeping, meaning, add as many requests to the bulk request as it reaches a 100MB size. Then submit the bulk request and after completion start another bulk request.
• Another option would be to submit a bulk request as always and only when receiving the exception, then handle it gracefully. For example, by dividing the bulk request into smaller chunks.
