Redpanda Use the Redpanda connector to get data from a Redpanda topic into Decodable. If you are looking for information about how to create a connection to get data into Redpanda from Decodable, see Redpanda in the Connect to a data destination chapter. Overview Connector name redpanda Types source, sink Delivery guarantee at least once or exactly once, based on configuration Create a connection to Redpanda Prerequisites If you want to use TLS or mTLS to secure the connection between Decodable and Redpanda, then you must have a self-signed or third-party signed server certificate and a private key associated with that server certificate. Because Redpanda is fully compatible with Apache Kafka, the configuration required to process data from Redpanda into Decodable is the same as when you process data from Kafka. For detailed instructions on how to create a TLS or mTLS secured connection between Redpanda and Decodable, see the following topics. How to set up Mutual TLS Authentication with Kafka. How to set up TLS Encryption with Kafka. Steps Follow these steps to send data from Decodable into Redpanda. From the Connections page, select the Redpanda connector and complete the following fields. UI Field Property Name in the Decodable CLI Description Connection Type N/A Select Source to use this connector to get data into Decodable. Bootstrap Servers bootstrap.servers A comma-separated list of your Kafka brokers. You must enter at least one broker. Enter each broker in the format: :. For example: broker-a:9092,broker-b:9092 The broker list cannot contain any spaces. Topic topic A semicolon-separated list of one or more topic names to read data from. Broker Security Protocol security.protocol Specify the security protocol to use when connecting to a broker. Must be one of the following: - PLAINTEXT -TLS: See TLS Properties for information about the additional fields you need to provide when using TLS. -SASL_SSL: See SASL Properties for information about the additional fields you need to provide when using SASL. -SASL_PLAINTEXT: See SASL Properties for information about the additional fields you need to provide when using SASL. For more information about the difference between these protocols, see the Security section. Value Format value.format The format for data in Redpanda that you want to send to Decodable. Must be one of the following: - JSON - Raw - Avro - Debezium (JSON) If you want to send Change Data Capture (CDC) data through this connector, then you must select Debezium (JSON). Parse Error Policy parse-error-policy Select the behavior that you want when Decodable detects a validation error in the incoming data. When set to FAIL, the connection will be stopped. When set to IGNORE, the connection continues to run and send records, however, invalid records are ignored. Consumer Group ID properties.group.id Optional. Name of the Redpanda consumer group that you want to get data from. Scan Startup Mode scan.startup.mode The offset mode that Decodable uses to determine where to start consuming data. Must be one of the following: - group offset: Start from committed offsets in ZK / Kafka brokers of a specified consumer group. You must specify the consumer group in the Consumer Group ID or properties.group.id field. - earliest offsets: Start from the earliest offset possible. - latest offset: Start from the latest offset. - timestamp: Start from user-supplied timestamp for each partition. - specific offsets: Start from user-supplied specific offsets for each partition. Consumer Offset Reset Strategy properties.auto.offset.reset Select the behavior that you want when there is no initial offset in Redpanda (e.g. a new consumer group) or if the specified offset does not exist (e.g. that data has been deleted). Select the stream that you’d like to connect to this connector. Then, select Next. Define the connection’s schema. Select New Schema to manually enter the fields and field types present or Import Schema if you want to paste the schema in Avro or JSON format. The stream’s schema must match the schema of the data that you plan on sending through this connection. For more information about creating a stream or defining the stream schema, see Create and Manage Streams. Select Next when you are finished providing defining the connection’s schema. Give the newly created connection a Name and Description and select Save. Security Redpanda connections may optionally enable TLS, which encrypts all network traffic between Decodable and the brokers. In addition, the Redpanda connector supports mutual TLS (mTLS) which acts as a bidirectional mode of authentication with the brokers. To configure an mTLS connection, Decodable either provides a self-signed certificate or a certificate signing request (CSR) which you can sign to create a certificate for use with your brokers. See the How To guides for more information. SASL Properties When configuring a Redpanda connection to use How to set up SASL Authentication with Kafka, the following connection properties are used. UI Field Property Name in the Decodable CLI Description SASL Mechanism sasl.mechanism Specify the SASL mechanism as configured by the Redpanda broker. Supported values are ["PLAIN", "SCRAM-SHA-256", "SCRAM-SHA-512"]. SASL Username sasl.username The provided username or API key for authentication. SASL Password sasl.password The ID of the secret resource containing the password. If you are using the Decodable CLI, this is the ID of a secret resource in your account. Run decodable secret list to view available secrets or decodable secret --help for help with creating a new secret. Note: For security purposes, Decodable will never display secret values in plaintext. You can manage which users have permissions to create, delete, or modify secrets in the Access Control management view. See Roles, Groups, and Permissions for more information." TLS Properties When configuring a Redpanda connection to use mTLS or TLS, the following connection properties are used. UI Field Property Name in the Decodable CLI Description Broker Certificate tls.broker.certificate The broker’s public certificate used to encrypt traffic between external RedPanda brokers and Decodable. This property is only used when security.protocol=TLS. TLS Client Certificate tls.client.certificate Specify the client certificate used by Decodable to connect to external Redpanda brokers with mTLS. TLS Client Key tls.client.key The ID of the secret resource containing the client key. If you are using the Decodable CLI, this is the ID of a secret resource in your account. Run decodable secret list to view available secrets or decodable secret --help for help with creating a new secret. Note: For security purposes, Decodable will never display secret values in plaintext. You can manage which users have permissions to create, delete, or modify secrets in the Access Control management view. See Roles, Groups, and Permissions for more information." N/A tls.broker.signed_client_certificate Specify the client certificate signed by the broker. This property is required when tls.client.certificate.type=CSR.
