Abstract

An electronic data system comprises memory storage having stored data, file system software, and a transaction file. The transaction file is maintained by the file system software, and includes a plurality of transaction records corresponding to transactions that have been or are to be executed on one or more files and/or the or more directories of the file system. The file system software operates to organize and maintain the stored data in the files and directories and also to coalesce multiple transaction records meeting one or more criteria into fewer coalesced transaction records. The physical memory space required by the transaction file is reduced by the transaction record coalescing. The coalesced transaction records may be constructed so that they represent a logical result of applying each transaction record of a transaction record set in chronological order. Once the coalesced transaction records have been committed in the file system, the physical memory used by the original transaction records in the set may be reclaimed for further use (e.g., to store further transaction records) or may be otherwise removed from further use (e.g., when the physical memory is located in a block of memory in a flash-like memory device that has reached its maximum number of write and/or erase cycles).
