Adaptive sampling for data summarization

A computing device, comprising:

• a memory comprising machine executable code;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the machine to:
• assign numbers to blocks of storage that store groups of event records over a time period for evaluation, wherein the event records are organized within a database;
• identify a subset of the blocks as being assigned numbers exceeding a sampling threshold;
• sample event records within the subset of the blocks as sampled event records, wherein the sampled event records exclude event records within blocks assigned number not exceeding the sampling threshold;
• and
• generate an evaluation output based upon the sampled event records.

A non-transitory machine readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to perform operations comprising:

• assigning numbers to blocks of storage that store groups of event records over a time period for evaluation, wherein the event records are organized within a database;
• identifying a subset of the blocks as being assigned numbers exceeding a sampling threshold;
• sampling event records within the subset of the blocks as sampled event records, wherein the sampled event records exclude event records within blocks assigned number not exceeding the sampling threshold;
• and
• generating an evaluation output based upon the sampled event records.
