Managing schemas using Iglu

This documentation only applies to Snowplow Community Edition. See the feature comparison page for more information about the different Snowplow offerings.


To manage your schemas, you will need to have an Iglu Server installed (you will already have one if you followed the Community Edition Quick Start).

Alternatively, you can host a static Iglu registry in Amazon S3 or Google Cloud Storage.

Creating a schemaโ€‹

First, design the schema for your custom event (or entity). For example:

"$schema": "",
"description": "Schema for a button click event",
"self": {
"vendor": "com.snowplowanalytics",
"name": "button_click",
"format": "jsonschema",
"version": "1-0-0"
"type": "object",
"properties": {
"id": {
"type": "string",
"minLength": 1
"target": {
"type": "string"
"content": {
"type": "string"
"required": ["id"],
"additionalProperties": false

Next, save this schema in the following folder structure, with a filename of 1-0-0 (without any extension):

โ””โ”€โ”€ com.snowplowanalytics
โ””โ”€โ”€ button_click
โ””โ”€โ”€ jsonschema
โ””โ”€โ”€ 1-0-0

If you update the vendor or the name in the example, you should update the above path too.

Finally, to upload your schema to your Iglu registry, you can use igluctl:

igluctl static push --public <local path to schemas> <Iglu server endpoint> <iglu_super_api_key>

See the Igluctl reference page for more information on the static push command.
