Auto unload

A method comprising:

• determining, by at least one processor, that a number of accesses to a table occurring within a time period has satisfied an access threshold;
• identifying, by the at least one processor and in response to the determining, a first timestamp indicating a most recent access to the table;
• determining, by the at least one processor, whether a difference between a current timestamp and the first timestamp satisfies a first time threshold;
• comparing, by the at least one processor and in response to the difference satisfying the first time threshold, a ratio of the difference and a size of the table to a ratio threshold;
• unloading, by the at least one processor and in response to satisfying the ratio threshold, the table;
• retrieving, by the at least one processor and in response to the unloading, feedback indicating a time period between the unloading of the table and a reloading of the table;
• and
• adjusting, by the at least one processor and based on the feedback, the first time threshold and/or the ratio threshold.

A non-transitory computer readable medium storing instructions which, when executed by at least one processor, cause operations comprising:

• determining that a number of accesses to a table occurring within a time period has satisfied an access threshold;
• identifying, in response to the determining, a first timestamp indicating a most recent access to the table;
• determining whether a difference between a current timestamp and the first timestamp satisfies a first time threshold;
• comparing, in response to the difference satisfying the first time threshold, a ratio of the difference and a size of the table to a ratio threshold;
• unloading, in response to satisfying the ratio threshold, the table;
• retrieving, in response to the unloading, feedback indicating a time period between the unloading of the table and a reloading of the table;
• and
• adjusting, based on the feedback, the first time threshold and/or the ratio threshold.
