Forward Compatibility

PreviousBackward CompatibilityNextFull Compatibility

Last updated 1 year ago

Also two variants here:

  • FORWARD - Consumers with previous version of the schema (X - 1) can read data produced by Producers with a new schema version (X)

  • FORWARD_TRANSITIVE - Consumers with any previous version of the schema (X - 1, X - 2, ...) can read data produced by Producers with a new schema version (X)

The operations that preserve forward compatibility are:

  • Adding a new field

    • Consumers will ignore the fields that are not defined in their schema version

  • Deleting optional fields (with default values)

    • Consumers will use the default value for the missing fields defined in their schema version
