Hi,

```
 Thank you in advance.

  Is there a way to keep two elasticsearch clusters in sync?

```

I have a 5.6 elasticsearch cluster which is getting data inserted through spark and I have another 7.6 elasticsearch cluster that is running and I want to keep the data in sync between the 2 clusters.

Welcome!

Not really with the versions you have. It's possible with Cross Cluster Replication (CCR) in the 7.x series.

Otherwise, as you are writing data to Spark, you can may be have 2 logstash instances which read the same flow and send data to both clusters?
