Schema Validation

Tigris requires that all documents in a collection conform to a schema. A schema defines all the fields that make up the document in a collection.

A schema is a blueprint for the application that outlines how data should be structured. More importantly, schemas make data more accessible and less prone to errors, making them an essential part of application architecture.

Validation​

Tigris performs schema validations during inserts and updates to the collection. Schema validation is performed in the following ways:

  • Newly inserted documents are checked for validation
  • During an update, only the new field values specified in the update operation are checked for validation

What happens when a document fails validation​

When an insert or update operation fails schema validation, Tigris rejects the operation and does not write the document to the collection.
