Release Notes

Jeffail/benthos (github.com/Jeffail/benthos/v3)

v4.26.0

Compare Source

For installation instructions check out the getting started guide.

Added
  • Field credit added to the amqp_1 input to specify the maximum number of unacknowledged messages the sender can transmit.
  • Bloblang now supports root-level if statements.
  • New experimental sql cache.
  • Fields batch_size, sort and limit added to the mongodb input.
  • Field idemponent_write added to the kafka output.
Changed
  • The default value of the amqp_1.credit input has changed from 1 to 64.
  • The mongodb processor and output now support extended JSON in canonical form for document, filter and hint mappings.
  • The open_telemetry_collector tracer has had the url field of gRPC and HTTP collectors deprecated in favour of address, which more accurately describes the intended format of endpoints. The old style will continue to work, but eventually will have its default value removed and an explicit value will be required.
Fixed
  • Resource config imports containing % characters were being incorrectly parsed during unit test execution. This was a regression introduced in v4.25.0.
  • Dynamic input and output config updates containing % characters were being incorrectly parsed. This was a regression introduced in v4.25.0.

v4.25.0

Compare Source

For installation instructions check out the getting started guide.

Added
  • Field address_cache added to the socket_server input.
  • Field read_header added to the amqp_1 input.
  • All inputs with a codec field now support a new field scanner to replace it. Scanners are more powerful as they are configured in a structured way similar to other component types rather than via a single string field, for more information check out the scanners page.
  • New diff and patch Bloblang methods.
  • New processors processor.
  • Field read_header added to the amqp_1 input.
  • A debug endpoint /debug/pprof/allocs has been added for profiling allocations.
  • New cockroachdb_changefeed input.
  • The open_telemetry_collector tracer now supports sampling.
  • The aws_kinesis input and output now support specifying ARNs as the stream target.
  • New azure_cosmosdb input, processor and output.
  • All sql_* components now support the gocosmos driver.
  • New opensearch output.
Fixed
  • The javascript processor now handles module imports correctly.
  • Bloblang if statements now provide explicit errors when query expressions resolve to non-boolean values.
  • Some metadata fields from the amqp_1 input were always empty due to type mismatch, this should no longer be the case.
  • The zip Bloblang method no longer fails when executed without arguments.
  • The amqp_0_9 output no longer prints bogus exchange name when connecting to the server.
  • The generate input no longer adds an extra second to interval: '@​every x' syntax.
  • The nats_jetstream input no longer fails to locate mirrored streams.
  • Fixed a rare panic in batching mechanisms with a specified period, where data arrives in low volumes and is sporadic.
  • Executing config unit tests should no longer fail due to output resources failing to connect.
Changed
  • The parse_parquet Bloblang function, parquet_decode, parquet_encode processors and the parquet input have all been upgraded to the latest version of the underlying Parquet library. Since this underlying library is experimental it is likely that behaviour changes will result. One significant change is that encoding numerical values that are larger than the column type (float64 into FLOAT, int64 into INT32, etc) will no longer be automatically converted.
  • The parse_log processor field codec is now deprecated.
  • WARNING: Many components have had their underlying implementations moved onto newer internal APIs for defining and extracting their configuration fields. It's recommended that upgrades to this version are performed cautiously.
  • WARNING: All AWS components have been upgraded to the latest client libraries. Although lots of testing has been done, these libraries have the potential to differ in discrete ways in terms of how credentials are evaluated, cross-account connections are performed, and so on. It's recommended that upgrades to this version are performed cautiously.

Added
  • The -e/--env-file cli flag for importing environment variable files now supports glob patterns.
  • Environment variables imported via -e/--env-file cli flags now support triple quoted strings.

v4.21.0

Compare Source

For installation instructions check out the getting started guide.

Added
  • 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.

  • Field endpoint_params added to the oauth2 section of HTTP client components.
Fixed
  • 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".

Changed
  • The snowflake_put output is now beta.
  • Endpoints specified by http_server components using both the general http server block or their own custom server addresses should no longer be treated as path prefixes unless the path ends with a slash (/), in which case all extensions of the path will match.

The full change log can be found here.

v4.15.0

Compare Source

For installation instructions check out the getting started guide.

The full change log can be found here.

v4.14.0

Compare Source

For installation instructions check out the getting started guide.

  • 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.

  • 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.

  • The resource input should no longer block the first layer of graceful termination.
Changed
  • The catch method now defines the context of argument mappings to be the string of the caught error. In previous cases the context was undocumented, vague and would often bind to the outer context. It's still possible to reference this outer context by capturing the error (e.g. .catch(_ -> this)).

Added
  • Go API: A new BatchError type added for distinguishing errors of a given batch.
Fixed
  • Rolled back kafka input and output underlying sarama client library to fix a regression introduced in 4.9.0 😅 where invalid configuration (Consumer.Group.Rebalance.GroupStrategies and Consumer.Group.Rebalance.Strategy cannot be set at the same time) errors would prevent consumption under certain configurations. We've decided to roll back rather than upgrade as a breaking API change was introduced that could cause issues for Go API importers (more info here: https://github.com/Shopify/sarama/issues/2358).
