I want to love elasticsearch and they keep making it harder. On top of this open source backflip, their sales staff would put Oracle to shame. Pressure tactics, making clients pay 5 figures for few hours of ES consultant time, very expensive training/certification (and cert expires every 2 years) - among few of them.
AWS gave us consultant time for no charge, guess who we picked to run our ES load.
