I need a brief explanation of how can I convert MySQL data to Elastic Search using logstash. can anyone explain the step by step process about this
You can do it using the jdbc input plugin for logstash.
Here is a config example.
This is a broad question, I don't know how much you familiar with MySQL
and ES
. Let's say you have a table user
. you may just simply dump it as csv
and load it at your ES
will be good. but if you have a dynamic data, like the MySQL
just like a pipeline, you need to write a Script
to do those stuff. anyway you can check the below link to build your basic knowledge before you ask How.
Also, since you probably want to know how to covert your CSV
to json file, which is the best suite for ES to understand.
Let me provide you with a high level instruction set.
