Hi Team,

I have used logstash to parse the log file then using elasticsearch to save the index and kibana to visualize it.

My problem is that for a particular log file (Path) i am getting value of one filed only once and for rest of the rows, for same file(Path), i want to update that filed with the same value which i got in one of the record.

sample sql query:

update Path A set A.Filed = B.Filed  
from Path A, Path B  
where A.Path = B.Path and A.Filed = null.

Is it possible to update it in elasticsearch using kibana dev tool or how can i achieve this. Any sample query to handle such type of situation

Thanks

You cannot do this with a query, you would need to do it before you sent it to Elasticsearch for indexing.
