lambda-taggable-createDocument

This Lambda is used to add / update documents in the Numo Labs taggable system.
The tagging system structure is shown below:

The taggable system stores all documents in an S3 Bucket ('numo-taggy').
e.g: https://numo-taggy.s3.amazonaws.com/ci/geo/geonames/geo%3Ageonames.2985244.json
When a tag (.json file) is inserted/updated in the S3 Bucket this triggers two Lambda functions:

• 1 - Update record in CloudSearch taggy-ci: https://github.com/numo-labs/lambda-taggable-cloudsearch-indexer
• 2 - Update record in Neo4J: https://github.com/numo-labs/lambda-taggable-neo4j-indexer

Both CloudSearch & Neo4J are run as a managed service in the AWS cloud. Ask Pascal for for more info.

The lambda function is invoked with the tag data as fields in the event object i.e the event object has the form:

{
  _id, // string
  location, // object with lat and lon keys
  displayName, // string
  tags, // an array of objects
  metadata, // an array of objects
  markets // object of objects
}

If you need a sample event to test-run this lambda in the AWS Console, see: /test/fixtures/test_hotel_tag.json
In the AWS Console you should see something like:
`--> Tag test:hotel.mhid.77bvb7p Saved to S3: https://numo-taggy.s3-eu-west-1.amazonaws.com/ci/test/hotel/test%3Ahotel.mhid.77bvb7p.json
The URL is is your newly created/updated tag.
