Highlights from the upstream Collector changelog

🛑 Breaking changes 🛑

• pkg/stanza: Move filelog.container.removeOriginalTimeField feature gate to stable (open-telemetry/opentelemetry-collector-contrib#33389)
• pkg/ottl: Support dynamic indexing of maps and slices. (open-telemetry/opentelemetry-collector-contrib#36644)

💡 Enhancements 💡

• exporterhelper: Add blocking option to control queue behavior when full (open-telemetry/opentelemetry-collector#12090)
• debugexporter: Add EventName to debug exporter for Logs. EventName was added as top-level field in the LogRecord from 1.5.0 of proto definition. (open-telemetry/opentelemetry-collector#11966)
• confighttp: Added support for configuring compression levels. (open-telemetry/opentelemetry-collector#10467)
  A new configuration option called CompressionParams has been added to confighttp.
  This allows users to configure the compression levels for the confighttp client.
• exporterhelper: Change the memory queue implementation to not pre-allocate capacity objects. (open-telemetry/opentelemetry-collector#12070)
  This change improves memory usage of the collector under low utilization and is a prerequisite for supporting different other size limitations (number of items, bytes).
• pkg/ottl: Add the Nanosecond converter to return the nanosecond component from the specified time.Time (open-telemetry/opentelemetry-collector-contrib#37042)
• pkg/ottl: Add the Second converter to return the second component from the specified time.Time (open-telemetry/opentelemetry-collector-contrib#37042)
• pkg/ottl: Enhanced error messages for invalid cache access and introduced options to configure their values within the OTTL contexts. (open-telemetry/opentelemetry-collector-contrib#29017)
• pkg/ottl: Add the FormatTime function to convert time.Time values to human-readable strings (open-telemetry/opentelemetry-collector-contrib#36870)
• resourcedetectionprocessor: This enhancement detects AWS EKS cloud account ID (open-telemetry/opentelemetry-collector-contrib#37179)
• resourcedetectionprocessor: Introduce kubeadm detector to retrieve local cluster name. (open-telemetry/opentelemetry-collector-contrib#35116)
• k8sattributesprocessor: For pods with only one container, the container.id and k8s.container.name are not longer required in the resource attributes to add the container attributes (open-telemetry/opentelemetry-collector-contrib#34189)
• tailsamplingprocessor: Added debug logging to the sampling decision caches. (open-telemetry/opentelemetry-collector-contrib#37038)
• tailsamplingprocessor: Improved not sampled decision cache usage and deleting traces from the internal map when they are in a decision cache. (open-telemetry/opentelemetry-collector-contrib#37189)

🧰 Bug fixes 🧰

• k8sattributesprocessor: Ensure the pods gathered by the processor contain the information about their related replica sets and deployments after the initial sync (open-telemetry/opentelemetry-collector-contrib#37056)
• pkg/ottl: Fix bug with replace_all_matches and replace_all_patterns that caused non-string values to be changed to empty string when matching against empty string. (open-telemetry/opentelemetry-collector-contrib#37071)
• tailsamplingprocessor: Fixed sampling policy evaluation debug logging batch metrics (e.g. sampled). (open-telemetry/opentelemetry-collector-contrib#37040)
• tailsamplingprocessor: Late span age histogram should include sampled traces. (open-telemetry/opentelemetry-collector-contrib#37180)
