0.6.0

Gollum 0.6.0 contains breaking changes over version 0.5.x.
Please read the release notes carefully

Gollum 0.6.0 dependency management switches from go-dep to go-modules.
As of this is recommended to use go 1.11 or later for development.
Go 1.10 and 1.9 are still supported. Support for Go 1.8 or older has been dropped.

No Linux/ARMv6 binary has been included in this build due to a build error in the sarama library.

New with 0.6.0

• Added a new flag "-mt" to choose the metrics provider (currently only prometheus).
• Consumer.File setting "Files" now supports glob patterns.
• Consumer.Syslog now allows non-standard protocol types (see issue #234)
• Message metadata can now store arbitrary data
• When not setting the numbers of CPU, gollum will try to use cgroup limits
• format.Cast for changing metadata field types
• format.Override to set static field values

Breaking changes with 0.6.0

• Format.SplitPick default delimiter is now ","
• Multiple formatters have been renamed to support the new metadata model
• Metrics are now collected using go-metrics. This allows e.g. prometheus output (default).
  Old-style metrics have been removed and many metrics names have changed.
• Consumer.File setting "File" has been renamed to "Files"
• Consumer.File setting "OffsetFile" changed to "OffsetPath" to support multiple offset files per consumer.
• Consumer.File setting "PollingDelay" has been renamed to "PollingDelayMs".
• Metadata type has changed from map[string][]byte to tgo.MarshalMap.
• Deserializing messages written by v0.5.x will lead to metadata of those message to be discarded.
• Removed support for go 1.8 in order to allow sync.Map
• The functions Message.ResizePayload and .ExtendPayload have been removed in favor if go's slice internal functions.
