This invention relates to the field of experimental data storage technology for nuclear fusion devices, and discloses a method for large-scale EPICS data archiving based on a time-series database. The method involves acquiring process variables in an event-driven acquisition mode through an embedded channel access protocol data acquisition module and writing them into buffered memory channels. Through group aggregation and batch persistence, the process variables are grouped into fixed-size groups, each group corresponding to an aggregation coroutine. The latest event data is read non-blockingly from the buffered memory channels of each group at fixed intervals. Metadata mapping is used to convert the process variable names into device paths and measurement value names in the time-series database, assembling them into a sparse wide table. Null value columns in the sparse wide table are filtered, and the data is then batch-written into a distributed time-series database through a connection pool. This invention achieves stable high-throughput writing and low-latency retrieval of large-scale experimental data in the EPICS system, and provides an efficient data access interface for subsequent artificial intelligence training and inference platforms.

This invention provides a method for resuming processing after a pause in the encryption / decryption process of large amounts of data. First, a database index containing a hierarchical directory structure is constructed based on the target task. During processing, a bottom-up strategy is used to extract the current processing directory, and after the encryption / decryption loop of a single file is closed, the synchronization status of the file count variable is updated using database transactions. Upon capturing an interrupt signal, the system detects the memory stream buffer and forces a delayed response until the current single file completes its disk write-back operation and safely releases the underlying file handle, thereby locking the processing boundary and solidifying the paused state. When the program resumes execution, a Boolean error-proofing feature bit is used to verify the data write-to-disk status and calculate the effective skip amount. By performing an index span offset operation on the file traversal sequence, already processed files are precisely skipped, and subsequent tasks continue. This invention combines memory mapping, connection pooling, and multi-process concurrency techniques to effectively solve the problems of resource congestion and progress loss during massive data processing while ensuring the integrity of single files.
