v4.14.0

For installation instructions check out the getting started guide.

Added

• The -e/--env-file cli flag can now be specified multiple times.
• New studio pull cli subcommand for running Benthos Studio session deployments.
• Metadata field kafka_tombstone_message added to the kafka and kafka_franz inputs.
• Method SetEnvVarLookupFunc added to the stream builder API.
• The discord input and output now use the official chat client API and no longer rely on poll-based HTTP requests, this should result in more efficient and less erroneous behaviour.
• New bloblang timestamp methods ts_add_iso8601 and ts_sub_iso8601.
• All SQL components now support the trino driver.
• New input codec csv-safe.
• Added base64rawurl scheme to both the encode and decode Bloblang methods.
• New find_by and find_all_by Bloblang methods.
• New skipbom input codec.
• New javascript processor.

Fixed

• The find_all bloblang method no longer produces results that are of an unknown type.
• The find_all and find Bloblang methods no longer fail when the value argument is a field reference.
• Endpoints specified by HTTP server components using both the general http server block or their own custom server addresses should now be treated as path prefixes. This corrects a behavioural change that was introduced when both respective server options were updated to support path parameters.
• Prevented a panic caused when using the encrypt_aes and decrypt_aes Bloblang methods with a mismatched key/iv lengths.
• The snowpipe field of the snowflake_put output can now be omitted from the config without raising an error.
• Batch-aware processors such as mapping and mutation should now report correct error metrics.
• Running benthos blobl server should no longer panic when a mapping with variable read/writes is executed in parallel.
• Speculative fix for the cloudwatch metrics exporter rejecting metrics due to minimum field size of 1, PutMetricDataInput.MetricData[0].Dimensions[0].Value.
• The snowflake_put output now prevents silent failures under certain conditions. Details here.
• Reduced the amount of pre-compilation of Bloblang based linting rules for documentation fields, this should dramatically improve the start up time of Benthos (~1s down to ~200ms).
• Environment variable interpolations with an empty fallback (${FOO:}) are now valid.
• Fixed an issue where the mongodb output wasn't using bulk send requests according to batching policies.
• The amqp_1 input now falls back to accessing Message.Value when the data is empty.

Changed

• When a config contains environment variable interpolations without a default value (i.e. ${FOO}), if that environment variable is not defined a linting error will be emitted. Shutting down due to linting errors can be disabled with the --chilled cli flag, and variables can be specified with an empty default value (${FOO:}) in order to make the previous behaviour explicit and prevent the new linting error.
• The find and find_all Bloblang methods no longer support query arguments as they were incompatible with supporting value arguments. For query based arguments use the new find_by and find_all_by methods.
