Abstract
The use of log marking (otherwise known as 'coloring') of sub-portions of a log that records actions (e.g., data operations) performed by a computing system. The log is composed of multiple sub-portions, such as virtual log files, which are successively added to the log as the log grows. For instance, the sub-portions may be virtual log files of the log. The principles described herein change the use of log marking depending on which sub-portion of the log is being marked. If the computing system fails, and recovery is needed, the recovery process can thus deterministically identify where the last written log record is.
