I have been trying to import my mySQL database into Elasticsearch through Logstash but I am stuck (for two days now) to separate three columns into separate fields.
I want to split these into different fields so it displays as:
"dr_behaviour_Patient Healer": "5",
"dr_behaviour_Couldn’t Care Less": "5"
Yes, you are right. It works. I will ensure that the key will not have square brackets. Thank you very much!!!
If I have other fields with similar issues, should I add another set of kv filter with that field as the source? In this way, I will have three sets of KV filters with different source and prefix. for example,
Apache, Apache Lucene, Apache Hadoop, Hadoop, HDFS and the yellow elephant
