Docs Connect Components Outputs aws_dynamodb aws_dynamodb Type: OutputCache Available in: Cloud, Self-Managed Inserts items into a DynamoDB table. Introduced in version 3.36.0. Common Advanced # Common config fields, showing default values output: label: "" aws_dynamodb: table: "" # No default (required) string_columns: {} json_map_columns: {} max_in_flight: 64 batching: count: 0 byte_size: 0 period: "" check: "" # All config fields, showing default values output: label: "" aws_dynamodb: table: "" # No default (required) string_columns: {} json_map_columns: {} ttl: "" ttl_key: "" max_in_flight: 64 batching: count: 0 byte_size: 0 period: "" check: "" processors: [] # No default (optional) region: "" endpoint: "" credentials: profile: "" id: "" secret: "" token: "" from_ec2_role: false role: "" role_external_id: "" max_retries: 3 backoff: initial_interval: 1s max_interval: 5s max_elapsed_time: 30s The field string_columns is a map of column names to string values, where the values are function interpolated per message of a batch. This allows you to populate string columns of an item by extracting fields within the document payload or metadata like follows: string_columns: id: ${!json("id")} title: ${!json("body.title")} topic: ${!meta("kafka_topic")} full_content: ${!content()} The field json_map_columns is a map of column names to json paths, where the dot path is extracted from each document and converted into a map value. Both an empty path and the path . are interpreted as the root of the document. This allows you to populate map columns of an item like follows: json_map_columns: user: path.to.user whole_document: . A column name can be empty: json_map_columns: "": . In which case the top level document fields will be written at the root of the item, potentially overwriting previously defined column values. If a path is not found within a document the column will not be populated. Credentials By default Redpanda Connect will use a shared credentials file when connecting to AWS services. It’s also possible to set them explicitly at the component level, allowing you to transfer data across accounts. You can find out more in Amazon Web Services. Performance This output benefits from sending multiple messages in flight in parallel for improved performance. You can tune the max number of in flight messages (or message batches) with the field max_in_flight. This output benefits from sending messages as a batch for improved performance. Batches can be formed at both the input and output level. You can find out more in this doc. Fields table The table to store messages in. Type: string string_columns A map of column keys to string values to store. This field supports interpolation functions. Type: object Default: {} # Examples string_columns: full_content: ${!content()} id: ${!json("id")} title: ${!json("body.title")} topic: ${!meta("kafka_topic")} json_map_columns A map of column keys to field paths pointing to value data within messages. Type: object Default: {} # Examples json_map_columns: user: path.to.user whole_document: . json_map_columns: "": . ttl An optional TTL to set for items, calculated from the moment the message is sent. Type: string Default: "" ttl_key The column key to place the TTL value within. Type: string Default: "" max_in_flight The maximum number of messages to have in flight at a given time. Increase this to improve throughput. Type: int Default: 64 batching Allows you to configure a batching policy. Type: object # Examples batching: byte_size: 5000 count: 0 period: 1s batching: count: 10 period: 1s batching: check: this.contains("END BATCH") count: 0 period: 1m batching.count A number of messages at which the batch should be flushed. If 0 disables count based batching. Type: int Default: 0 batching.byte_size An amount of bytes at which the batch should be flushed. If 0 disables size based batching. Type: int Default: 0 batching.period A period in which an incomplete batch should be flushed regardless of its size. Type: string Default: "" # Examples period: 1s period: 1m period: 500ms batching.check A Bloblang query that should return a boolean value indicating whether a message should end a batch. Type: string Default: "" # Examples check: this.type == "end_of_transaction" batching.processors A list of processors to apply to a batch as it is flushed. This allows you to aggregate and archive the batch however you see fit. Please note that all resulting messages are flushed as a single batch, therefore splitting the batch into smaller batches using these processors is a no-op. Type: array # Examples processors: - archive: format: concatenate processors: - archive: format: lines processors: - archive: format: json_array region The AWS region to target. Type: string Default: "" endpoint Allows you to specify a custom endpoint for the AWS API. Type: string Default: "" credentials Optional manual configuration of AWS credentials to use. More information can be found in Amazon Web Services. Type: object credentials.profile A profile from ~/.aws/credentials to use. Type: string Default: "" credentials.id The ID of credentials to use. Type: string Default: "" credentials.secret The secret for the credentials being used. This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets. Type: string Default: "" credentials.token The token for the credentials being used, required when using short term credentials. Type: string Default: "" credentials.from_ec2_role Use the credentials of a host EC2 machine configured to assume an IAM role associated with the instance. Type: bool Default: false Requires version 4.2.0 or newer credentials.role A role ARN to assume. Type: string Default: "" credentials.role_external_id An external ID to provide when assuming a role. Type: string Default: "" max_retries The maximum number of retries before giving up on the request. If set to zero there is no discrete limit. Type: int Default: 3 backoff Control time intervals between retry attempts. Type: object backoff.initial_interval The initial period to wait between retry attempts. Type: string Default: "1s" backoff.max_interval The maximum period to wait between retry attempts. Type: string Default: "5s" backoff.max_elapsed_time The maximum period to wait before retry attempts are abandoned. If zero then no limit is used. Type: string Default: "30s" Back to top × Simple online edits For simple changes, such as fixing a typo, you can edit the content directly on GitHub.
