we are currently looking for a proper way to import some data into elasticsearch. The data is basically a relational datamodel split into several csv files.
For example we have a csv
customer with multiple columns and a unique ID for each row. Then we have another csv
constracts where a contract belongs to 1 customer. We now thought of importing all contracts as nested documents for the customer that matches with the foreign key customerId in
Is it possible to do something like this in logstash? So basically I need to output each document as a nested document to the parent document with a specific ID.
