Data Modeling

Vendia automatically converts your JSON Schema-based data model into a production-grade, distributed application composed of serverless public cloud resources.

Much as a conventional database turns a CREATE_TABLE definition into a single, centralized database, Vendia turns your JSON Schema-based data model into a distributed, decentralized database...and all the platform services needed to make that data available and useful in the cloud.

This guide explains how JSON schema types are converted into the GraphQL types that each node in your Uni can access, update, and subscribe to.

Scalars: Strings, booleans, and integers convert directly. JSON Schema number types will convert to GraphQL float types. JSON Schema date, time, and datetimes types will convert to system-specific scalars in GraphQL (e.g., AWS_DATE for GraphQL queries made on AWS). Top-level scalar and object types have create, get, update, and delete GraphQL commands generated automatically.
Arrays: Top-level arrays will be sharded and indexed. Top-level arrays have add, remove, update, get, and list GraphQL commands generated automatically. Data models that require large amounts of total storage or very high cardinality for nested arrays should be rewritten to make these appear as top-level arrays in order to expose them to indexing and sharding in the database.

Indexes

Indexes can be defined in the JSON schema to support efficient queries on arbitrary attributes. Indexes must be defined on top-level scalar attributes defined on existing array types in the schema.

The top-level directive x-vendia-indexes is used to define indexes on attributes. For example, to support an efficient list query of Orders by owner, an index can be defined in the schema referencing the owner property of the existing Order type.

{
 "$schema": "http://json-schema.org/draft-07/schema#",
 "$id": "http://vendia.net/schemas/sample.schema.json",
 "title": "Product",
 "description": "A product from Acme's catalog",
 "x-vendia-indexes": {
    "OrderOwnerIndex": [
      {
        "type": "Order",
        "property": "owner"
      }
    ]
  }
  ...
}

Now listing Orders and filtering on the owner property will use the new index, i.e.

list_OrderItems(filter: {owner: {eq: "bob@acme.com"}}) {
  nextToken        
  _OrderItems {
    _id
    owner
    orderContent
  }
}

Indexes can be used with the following GraphQL operators:

eq
ne
gt
lt
le
ge
between
beginsWith
and

Indexes can be defined on the following JSON schema property types:

string
number
integer

There is a limit to the number of indexes that can be created on a Uni.

Tier	Maximum Indexes per Uni
Free Tier	1
Paid Tiers	12

Indexes are defined at Uni registration time. To add indexes to an existing Uni, please contact Vendia.
