Auto-upload Elastisearch template mapping with Apache Camel

When feeding data into Elastisearch, one important step is to configure the correct template for the index/type so that, for instance, numeric fields are stored as numbers to ensure that they can be sorted by and/or confronted correctly.

The Elasticsearch Logstash plugin has a handy option just for this purpose. If you are not using Logstash you have to do it yourself, eithr through configuration mgmt, startup scripts or simply manaully launching the appropriate curl command.

If you have followed my previous post on using Apache Camel to feed sql data into Elasticsearch then it might come natural to attempt to use Camel also for the purpose of uploading the template mapping.
