Ween saving a profile you can choose how you want to store log rows once retrieved from the log files.
All log rows are loaded in memory and are queried directly in memory. The next time you load the same profile all log rows need to be parsed again. Log files loaded without a profile or with the free edition are always loaded in normal mode.
In this mode a SQLite database will be automatically created for the profile and all log rows will be stored in it. Then only filtered log rows are loaded in memory;
Works like the default database mode but additionally you can choose between a SQLite, MySQL or SQL server database.
•Use the normal mode for log files you analyze only occasionally because it is slow to parse log files every time.
•Use the cache mode if you analyze the same logs very often but are interested only in recent log rows so the amount of data to load in memory is not too much.
•Use the database mode if you need to do an analysis over a very big number of rows (several millions). For example if you need to analyze several years of logs to display statistics.
