redpanda-data/connect v4.21.0 on GitHub

For installation instructions check out the getting started guide.

Fields client_id and rack_id added to the kafka_franz input and output.
New experimental command processor.
Parameter no_cache added to the file and env Bloblang functions.
New file_rel function added to Bloblang.
Field endpoint_params added to the oauth2 section of HTTP client components.

Allow comments in single root and directly imported bloblang mappings.
The azure_blob_storage input no longer adds blob_storage_content_type and blob_storage_content_encoding metadata values as string pointer types, and instead adds these values as string types only when they are present.
The http_server input now returns a more appropriate 503 service unavailable status code during shutdown instead of the previous 404 status.
Fixed a potential panic when closing a pusher output that was never initialised.
The sftp output now reconnects upon being disconnected by the Azure idle timeout.
The switch output now produces error logs when messages do not pass at least one case with strict_mode enabled, previously these rejected messages were potentially re-processed in a loop without any logs depending on the config. An inaccuracy to the documentation has also been fixed in order to clarify behaviour when strict mode is not enabled.
The log processor fields_mapping field should no longer reject metadata queries using @ syntax.
Fixed an issue where heavily utilised streams with nested resource based outputs could lock-up when performing heavy resource mutating traffic on the streams mode REST API.
The Bloblang zip method no longer produces values that yield an "Unknown data type".
