Detailed Description

Factory class for creating and managing MetricsReporter instances.

This class provides a registry-based factory for creating MetricsReporter implementations. Custom reporter implementations can be registered using the Register() method.

Member Function Documentation

Combine()

std::shared_ptr< MetricsReporter > iceberg::MetricsReporters::Combine ( std::shared_ptr< MetricsReporter >  first, std::shared_ptr< MetricsReporter >  second  )

static

Combine two reporters into one.

Parameters

first	First reporter, may be nullptr.
second	Second reporter, may be nullptr.

Returns

Combined reporter, or nullptr if both inputs are nullptr.

Load()

Result< std::unique_ptr< MetricsReporter > > iceberg::MetricsReporters::Load ( const std::unordered_map< std::string, std::string > &  properties )

static

Load a metrics reporter based on properties.

This method looks up the "metrics-reporter-impl" property to determine which reporter implementation to create. If not specified, returns a NoopMetricsReporter.

Parameters

properties

Configuration properties containing reporter type.

Returns

A new MetricsReporter instance or an error.

Register()

Status iceberg::MetricsReporters::Register ( std::string_view  reporter_type, MetricsReporterFactory  factory  )

static

Register a factory for a metrics reporter type.

Thread-safe. Registrations can be performed at any time, including concurrently with Load().

Parameters

reporter_type	Type identifier matched case-sensitively against the value of "metrics-reporter-impl" in catalog properties, mirroring Java's fully-qualified class-name lookup (e.g., "noop").
factory	Factory function that produces the reporter.

Returns

OK if the registration succeeded, or an error if the factory is invalid.
