The pipeline can have a series of processors that pre-process the data before indexing. Twenty processors are available, some are simple: { "append": { "field": "field1" "value": ["item2", "item3", "item4"] } } Others are more complex, like the Grok processor for regex with aliased expressions.

  27. 27. Get started at https://aws.amazon.com/elasticsearch-service/ Migrating from v2.3 to v5.1 The easy way: 1. Create a new Amazon Elasticsearch Service v5.1 cluster 2. Snapshot your v2.3 indexes 3. Restore the indexes to the v5.1 cluster … but this won’t get most of the benefits of v5.1 There are many breaking changes in v5, documented at https://www.elastic.co/guide/en/elasticsearch/reference/5.1/breaking-changes.html
  28. 28. Get started at https://aws.amazon.com/elasticsearch-service/ Three Things to Remember • Amazon Elasticsearch Service is a drop-in replacement for new and existing Elasticsearch workloads • Deploy, manage, and scale Elasticsearch more easily in the AWS cloud • Support for Elasticsearch 5.1 brings scripting, additional plugins and additional performance to Amazon Elasticsearch Service
