6You are in 'detached HEAD' state. You can look around, make experimental

7changes and commit them, and you can discard any commits you make in this

8state without impacting any branches by switching back to a branch.

10If you want to create a new branch to retain commits you create, you may

11do so (now or later) by using -c with the switch command. Example:

13 git switch -c <new-branch-name>

15Or undo this operation with:

17 git switch -

19Turn off this advice by setting config variable advice.detachedHead to false

382[info] io.kaizensolutions.jsonschema.JsonSchemaSerdesSpec

383[info] + JsonSchemaSerialization will automatically register the JSON Schema and allow you to send JSON data to Kafka 1s

384[info] + Enabling use latest (and disabling auto-registration) without configuring the client will fail 59ms

385[info] + Attempting to publish an incompatible change with auto-registration will fail 69ms

386[info] + Attempting to publish an incompatible change without auto-registration (using latest server schema) will fail 37ms

387[info] + Attempting to publish an incompatible change without auto-registration and not using the latest schema will fail 52ms

388[info] + Publishing a forward compatible change with auto-registration is allowed (in forward-compatibility mode) 205ms

389[info] + Reading data back from the topic with the latest schema is allowed provided you compensate for missing fields in your Decoder 3s

390[info] + Reading data back from the topic with an older schema is allowed 3s
