Hi there,

I'd like to ask. if an index enters a warm state, can it still perform write operations?  
i read [this blog](https://www.elastic.co/blog/implementing-hot-warm-cold-in-elasticsearch-with-index-lifecycle-management) but didn't found the information i need

Thanks

Unless you tell the policy to set it to read only, yes you can.
