Do we need to close() the bulk request? Or can we just ignore it if we have 0 requests in there?

If you mean BulkRequestBuilder, it is not closable, so you don't need to and and cannot close it.

By the way, have you seen BulkProcessor? It is typically a good place to start when you are dealing with bulk indexing from java.

Question for you.

We are using:

bulk.add(client.prepareUpdate(newIndexname, documentType, documentId)
.setScript(new Script(ScriptType.INLINE, "painless", "ctx._source." + DATA_FIELD + "." + field + ".remove(ctx._source." + DATA_FIELD + "." + field + ".indexOf(params.val));", params))
.setDetectNoop(false));

Will this work with the Bulk Processor?

There appears to be only these 2 calls with it?

bulkProcessor.add(new IndexRequest("twitter", "tweet", "1").source(/* your doc here */));
bulkProcessor.add(new DeleteRequest("twitter", "tweet", "2"));

The method signature is public BulkProcessor add(DocWriteRequest request) and DocWriteRequest is implemented by DeleteRequest, IndexRequest, and UpdateRequest. Did you try it? Did you get any error messages?

Thanks that works.
