Index Lookup and insert

Elastic Stack Logstash
1

Hi,

    I have an index named **"Student_info"** and have 2 fields in it (one is roll number, second is name). Now I am ingesting data in second index named **"penalties"** from some csv file (this csv contains **class** and **Roll_number**. During ingestion i want to match "Roll number"  from index "Student_info" and ingest the **name** from index **student_info** to index **penalties** during ingestion of CSV file using logstash. Can Some one please guide me on this.

Best Redards,

Sandeep

Have a look at Logstash's elasticsearch filter plugin.
