A computerized system comprising: one or more computer processors; and computer memory storing computer-useable instructions that, when used by the one or more computer processors, cause the one or more computer processors to perform operations comprising: performing an initialization operation comprising: creating an active log file for writing log data of an application during a logging operation; and creating a first spare file configured to replace the active log file during the logging operation, the first spare file being a replacement file for the active log file when the active log file meets a log file size limit; wherein the active log file and the first spare file are asynchronously created using background threads to avoid interfering with application functionality; accessing the active log file for logging data associated with the application, where segments of the active log file are configured to be mapped to memory to support writing received log data to the active log file, wherein the received log data is eventually saved to disk storage; executing the logging operation comprising writing log data of the application to a first segment of the active log file that is mapped to memory; and based on writing the log data, causing storage of the log data to disk storage. one or more computer processors; and computer memory storing computer-useable instructions that, when used by the one or more computer processors, cause the one or more computer processors to perform operations comprising: performing an initialization operation comprising: creating an active log file for writing log data of an application during a logging operation; and creating a first spare file configured to replace the active log file during the logging operation, the first spare file being a replacement file for the active log file when the active log file meets a log file size limit; wherein the active log file and the first spare file are asynchronously created using background threads to avoid interfering with application functionality; accessing the active log file for logging data associated with the application, where segments of the active log file are configured to be mapped to memory to support writing received log data to the active log file, wherein the received log data is eventually saved to disk storage; executing the logging operation comprising writing log data of the application to a first segment of the active log file that is mapped to memory; and based on writing the log data, causing storage of the log data to disk storage. performing an initialization operation comprising: creating an active log file for writing log data of an application during a logging operation; and creating a first spare file configured to replace the active log file during the logging operation, the first spare file being a replacement file for the active log file when the active log file meets a log file size limit; wherein the active log file and the first spare file are asynchronously created using background threads to avoid interfering with application functionality; accessing the active log file for logging data associated with the application, where segments of the active log file are configured to be mapped to memory to support writing received log data to the active log file, wherein the received log data is eventually saved to disk storage; executing the logging operation comprising writing log data of the application to a first segment of the active log file that is mapped to memory; and based on writing the log data, causing storage of the log data to disk storage.
