Viewing the Avro Schema Catalog Page¶
When you navigate to the dedicated page of a NoSQL schema, it will show all the data objects or data types loaded for this schema under the Schema field:
Key data type name property
Type data type definition
Title the title property, if applicable
Description the description property, if applicable
On this page, you can also view the Version History for the schema, if versioning is enabled for this VDS:
The Avro schema page includes the Other Metadata field. This field will list any Avro data type properties that are not included in the Alation’s logical model for Avro format and are not required by the NoSQL API but were loaded in addition to the required properties.
The Alation model uses the properties name, data type, title, and description to build the Schema table on the catalog page of a schema. If any other properties were loaded for the data types in this schema, they will appear under Other Metadata.
