How many concurrent writes does a Elasticsearch single node count as normal?
Environment : ELK 5 Machine performance: 4 core /16GB/SSD hard disk
Problem 1: Elasticsearch single node write speed (concurrent quantity) how many is normal?
I wrote the log to redis first, and then transferred it to Elasticsearch by logstash. The amount of concurrency was about 1500-2000 seconds, and I felt that the amount of concurrent Elasticsearch support of a single node was not very large. Is that normal?
Problem 2: in addition, if I want to improve the performance of writing to Elastic, can I only use clustering?
For example, if I want to achieve 4000/s concurrency, can I just add machines to the Elastic cluster?
