Hi I am looking for Sizing Elastic Search Cluster and came across below session which is very informative.
https://www.elastic.co/webinars/elasticsearch-sizing-and-capacity-planning I have few questions regarding the session -
- Cluster Sizing for Volume -> As per session we can have Memory:Storage Ratio of 1:30 for HOT , 1:1000 for Cold etc. so suppose i have 8 gb ram on a cold node then i can store 8000 GB data.
- Now if we consider number of shards.It is driven by Heap memory. We can have max 4 gb ram for heap so we can support at max 4* 20 =80 shards per node. One shard can be of max 50 GB so total supported data size = 80 * 50 = 4000 gb.
So 1st point in providing different storage data than 2nd point. Please help me understand.
