After several years of working with Elasticsearch and consulting many clients world-wide, it's time to share some trade secrets and lessons learned.
Elasticsearch is an open-source search engine server, which is easily scalable and being used by too many companies to mention for search and real-time analytics and log processing.
Come to learn about how Elasticsearch is used, what are the absolute no-no's and what are actually quite nice and innovative usages of it. I will also share useful pro-tips and a handful of takeaways you could apply to your existing (or future!) deployments of Elasticsearch.

Thank you Tony!

+1 for great content. It's refreshing to see some more in-depth insights. And thanks for taking a stab at the optimal shard size question and adding some perspective, even though there's no definitve answer (besides it depends, that is).

44:50 - I think It's explained in the documentation why this search approach is not always the best. If you want to search in languages that do not use delimiters - like Japanese, Chinese, you won't get the results you expect. In that case it's suggested to use n-grams.

"Security by obscurity is always a good idea."

@olgeezah 4 года назад

EasyMac308 sure it can give a false sense of security, but maybe it’s better than being the lowest hanging fruit.

@kevanschwitzer8585 4 года назад

Sure, I got what you mean :) However, I think of "security by obscurity" as an "extra", like using a non-standard port for a service. That would make some service less likely to be found and attempted to be exploioted in the first place. Not sufficient in and of itself, but useful in any case.

@MarceloBoeira23 3 года назад

isn't all security practices we have nowadays about obfuscation?

@aronpop1447 3 года назад

@@MarceloBoeira23 Yes but those obfuscations are tested by highly skilled professional cryptographers and penetration testers so algorithms like AES is the standard for a reason. Using AES is a good practice and it is NOT security by obscurity. Security by obscurity means that you implement some sort of custom-made encryption algorithms or do some other sort of "customized security" vs what the norm is so that attackers "cant figure it out". Trust me, they will have an easier time with your customized security than with AES, RSA..etc
