US 2023/0400984 A1 · VARIABLE SIZE RECORD STORAGE

Abstract

Embodiments of the disclosure provide for managing data stored in memory of a device. Maintaining variable-sized data records in an Internet-of-Things (IoT) device can comprise receiving data for a new record to be stored in a memory of the IoT device and searching data frames stored in the memory of the IoT device. The data frames can be stored in the memory of the IoT device in a circular manner and each data frame can store therein a data record of variable size. Searching the data frames can comprise locating a head data frame and a tail data frame. Each data frame can be validated during the searching of the plurality of data frames. In response to locating a valid tail data frame, the data for the new record can be written into a new tail frame for the plurality of data frames.
