2.10 Merge Log File Format
The merge log file format is an extension of the recoverable storage file format, as specified in section 2.2.4, and is used to store merge process information, as specified in section 2.9.
A file that implements the merge log file format identifies the type of the merge process and the full-text index components participating in the merge process: a master merge process creates and uses a master merge log file, and a shadow merge process creates and uses a shadow merge log file. It also identifies the AVDL files participating in the merge, if any.
