Hello,

My team and I are running a custom plugin that we made this year. This elasticsearch instance is running over two nodes. Our big problem is that the machine that we are using is slow (2 \* Intel core i3 - 1.3GHz) - it is a challenge to optimize our solution.

During the ingestion, we some times get this message in the logs:

> [2018-05-15T14:25:29,342][ERROR][o.e.a.b.TransportBulkAction] [grlaaa01] failed to execute pipeline for a bulk request

This message appears after quite a lot of entries (I believe 200 according to the error message). But does it mean that the last 200 entries are lost ? Partly ?  
According to [Why am I seeing bulk rejections in my Elasticsearch cluster? | Elastic Blog](https://www.elastic.co/blog/why-am-i-seeing-bulk-rejections-in-my-elasticsearch-cluster), no but can we be completely sure that some data aren't lost ?

By the way, the ingestion is done on one and only node, is that normal ?

Do you have any ideas of how optimizing the ingestion without touching the plugin ?

Best regards,

How many shards are you actively indexing into?

We are using 2 shards and 0 replicas.

```
PUT mdm
{
  "settings" : {
    "index" : {
      "number_of_shards" : 2, 
      "number_of_replicas" : 0 
    }
  }
}
```
