InfluxDB, an open-source time-series database, is being considered as a better option than OSI PI for handling real-time data in industries. OSI PI faces scalability and integration challenges as data volumes increase, whereas InfluxDB excels in handling large amounts of time series data with high-speed data writing, efficient storage, and advanced querying capabilities. InfluxDB provides a SQL-like query language, seamless integration with modern data tools and frameworks, and cost-effectiveness, making it an excellent choice for managing industrial data. Real-world success stories from companies like Térega and LBBC Technologies demonstrate the benefits of switching to InfluxDB, including improved scalability, flexibility, real-time monitoring, visualization, and analysis. As industries become more data-focused, having an efficient time series database like InfluxDB is critical, and it's set to be a major player in industrial IoT and digital transformation.
