I am using Elastic Search 5.2.2, Kibana 5.2.2 and X-Pack 5.2.2. I am planning for Data Encryption.
I use both Http and TCP call from my Java Code.
Will there be performance over head after SSL/TLS implementation.
I would like to understand performance of cluster post implementation as I have millions of Document In my Index and Size of Indices is around 60 GB.
That really depends on what kind of platform your running. Modern OS and hardware has optimizations for fast SSL/TLS support.
I suggest that you do benchmark using esrally in the target platform to verify.
Thank you. I also have same understanding with modern OS, Hardware and Software, performance overhead should be negligible.
Just FYI https://istlsfastyet.com/
I hope the question is just for
data encryption in transit, there would be other performance aspect you need to consider when doing
data encryption at rest.
Thank you for your input. I am not using Rest from my Java client code now, its Tcp call. My requirement is more of data encryption in transit. But yes some curiosity, if I go for Rest call in future, will there be much difference in performance. And what if I go for ECE cloud in future, where it supports Java REST Client only.
I am sorry if I confused you with
data encryption at rest as this is not related to RESTful web services. I was talking more on the storage of the data on File system https://en.wikipedia.org/wiki/Data_at_rest.
For REST client access, things should not be different in performance terms.
