Apache IoTDB vs OneTick

Apache IoTDB is an open-source industrial IoT time-series database for collecting, storing, managing, and analyzing device data across edge and cloud deployments. The project describes high-speed writes for millions of networked devices alongside fast reads. Query features include aligning time across devices and sensors, time-series computation, and aggregation by time dimensions. Ingestion options include IoTDB-SQL, JDBC, Java, C++, Python, and Go native APIs, REST, MQTT, CSV, and TsFile. Named analysis ecosystem examples include Hadoop, Spark, Flink, and Grafana. Deployment options include cloud installation, a desktop terminal tool, and synchronization between cloud and on-premise machines. The REST service is disabled by default and uses Basic Authentication except for the health check endpoint. Data and cluster permissions can be managed through users, roles, and privileges. The homepage states disk storage can cost less than $0.23 per GB. The project lists energy, aerospace, transportation, steel, and other IoT scenarios. Its JDBC documentation cautions that insert operations may not provide high-performance writing and recommends the Java Native API for Java applications.

OneTick is an enterprise platform for capturing tick data, managing it, and using it for streaming analytics and research. Its tools support historical simulations, back-tests, trading and market-making strategies, transaction-cost models, and real-time surveillance across equities, fixed income, futures, FX, options, and full order-book data. OneTick states that it has no limits on data volumes, peak rates, or stored-history length. OneTick Cloud provides Python, SQL, and REST API access, visual dashboards, and CSV and Parquet file access. Its global equities, futures, and options coverage spans more than 200 markets, with historical data reaching back decades. Machine-learning event processors support training, prediction, evaluation, and real-time learning, including support vector machines and k-means clustering. Deployments can be on-premise, in OneMarketData private or public cloud, or hybrid. Pricing is on request, and a 30-day trial is listed. Installing the Python package requires credentials from a OneMarketData representative.
