Apache IoTDB can handle the combination and grouping of data from various time periods in numerous devices by leveraging its time-series database architecture. IoTDB is optimized for handling large-scale time-series data and provides flexible data grouping options using the SQL-like query language.

Users can query and group data by a specified time range, device, sensor, or other metadata attributes. IoTDB also supports aggregation functions to summarize data and reduce query complexity. Additionally, the data can be stored in a distributed manner, allowing for efficient handling of large volumes of disparate data from multiple devices.

IoTDB's data modeling and database compression techniques further optimize data storage and retrieval across multiple devices and time periods. This allows for quick and efficient querying of combined data from multiple devices and time periods, providing meaningful insights for analysis and decision-making.
