Hello, We are trying to index having 83,286,866 documents. It takes around 3 days to index. This is the first time we are creating the indexes. Configuration: Elasticsearch 7.10 Windows Server 2016 Heap Size 16Gb RAM 64 GB CPU 16 core Shards 5 Node 1 Once indexed, the size of index is around 110GB. Can you please let me know if this config are the timings ok? Obviously, in a prod environment we can run something for 3 days, can you please suggest how can we improve the timings? ---
