Organizations are increasingly challenged to modernize their data infrastructure without disrupting daily operations, especially with the growing need for real-time analytics and advanced data processing. Traditional data historians, which have been used to store time-stamped machine and sensor data for reliability and compliance, are limited in their ability to handle modern workloads. The solution lies in augmenting existing systems with parallel data pipeline architectures, where data is streamed simultaneously into both a historian and a time series database like InfluxDB. This approach allows businesses to maintain their stable systems of record while gaining real-time visibility and analytics capabilities without the cost or risk of a full system replacement. By implementing techniques such as simultaneous ingestion, stream processing, and data validation, organizations can enhance their operational efficiency, reduce costs, and improve decision-making without compromising compliance and reliability. This strategy, which has been successfully applied in sectors like energy, helps organizations stay competitive and agile in a data-driven world.
