    # Before
    from opentelemetry.sdk._logs import LogData
    def export(self, batch: Sequence[LogData]) -> LogRecordExportResult:
        ...
    After
    from opentelemetry.sdk._logs import ReadableLogRecord
    def export(self, batch: Sequence[ReadableLogRecord]) -> LogRecordExportResult:
    ...

  • For Log Processors: Use ReadWriteLogRecord for processing, ReadableLogRecord for exporting

    # Before
    from opentelemetry.sdk._logs import LogData
    def on_emit(self, log_data: LogData):
        ...
    After
    from opentelemetry.sdk._logs import ReadWriteLogRecord, ReadableLogRecord
    def on_emit(self, log_record: ReadWriteLogRecord):
    # Convert to ReadableLogRecord before exporting
    readable = ReadableLogRecord(
    log_record=log_record.log_record,
    resource=log_record.resource or Resource.create({}),
    instrumentation_scope=log_record.instrumentation_scope,
