I have an issue while indexing nested document(60-100MB) using python client.
I have the last elastic version.
The indexing is very slow and some times I got readTimeOut.
After the indexing process the whole index will hangs and searches will be slow as well, I tried to recreate the index but that doesn't help.
I have 5 machines in the cluster (without replicas), each machine with 32 GB RAM, i configured the memory heap size to be 16 GB and disabled the swapping.
I tried to use the hot_thread to see what is going on but I didn't see any thread with high CPU.
Indexing/updating/searching works nice with small documents before trying to index the big json (60-100MB) .
Does my mapping impact the indexing process?
Do I need to configure memory or something ?
What should I do ?
