Hi
Im using elasticsearch 7.10.2 single node. Im getting this
Data too large, data for [\] would be [3985754120/3.7gb], which is larger than the limit of [3910375833/3.6gb], real usage: [3985754120/3.7gb], new bytes reserved: [0/0b], usages [request=0/0b, fielddata=6668796/6.3mb, in\_flight\_requests=0/0b, model\_inference=0/0b, accounting=3637590/3.4mb]: circuit\_breaking\_exception","statusCode":429,"error":"Too Many Requests"}
I increased heap size to 4GB. I have 24 GB RAM. Should I increase it further?
or Adding two more nodes , making it as 3 node elasticsearch cluster will help here?

Hi @RAM_NATHAN,
Increasing the heap size as you have done is the right thing to do. In terms of adding a node it really depends. There are some considerations listed in this [old topic](https://discuss.elastic.co/t/how-many-nodes-should-an-elasticsearch-cluster-have/227674) that could help you decide. There's also some further advice on choices of nodes in the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/high-availability-cluster-small-clusters.html) that can help too.
Hope that helps!

Please note that version is [EOL](https://www.elastic.co/support/eol) and no longer supported, you should be looking to upgrade as a matter of urgency.
