ESC

ESC is a lightweight wrapper for github.com/olivere/elastic which provides a quick setup for some common functions.

It enables quick integrations of bulk uploads to an ES cluster with minimal setup, often used for prototyping or quick scripts to upload data. It also provides an easy client setup for sending to AWS Elasticsearch Service, for use with an assumed role (Lambda, EC2, ECS, etc)

Basic:

esClient := esc.New("https://localhost:9200", "admin", "admin", true)

AWS

esClient := esc.NewAWS(esHost)

Batching uploads

The function : esClient.UpsertInterfaceStream provides an easy way to upload any struct type to es. By putting the list of structs into a channel of interfaces enabled the elasticsearch client to easily marshal the structs into JSON and upload them ES.

Make sure to close the channel when finished to end the upload

err := esClient.UpsertInterfaceStream(objStream, "my_index")
