, and tasks in other time wheels will continue to degrade into the lower tier of the time wheel as they approach expiration.Each wheel in a layered time wheel has its own lattice number and interval setting, and when the lowest layer of time is rotated round, the time wheel of the first layer turns a lattice.The layered time wheel greatly increases the range of time that can be represented, while reducing space consumption.As an example:The layered time wheel can express 8 8 8=512s time range, i

is twice times the previous lap, until the number of rows X2 is greater than the desired number of rows (@num). That is, to control the number of rows in the range less than or equal to @num, and finally to extract a portion of the existing rows to complement the bad rows. For example, the number of rows required is 13, go to 3 laps, @t has 8 lines, it will stop, because then turn into 16 lines, 8 distance 13 difference 5 lines finally by extracting

AWS-based time series processing application architecture When data is used as a periodic continuous measurement, it is called time series information. AWS's unique positioning addresses the scale-up challenges brought by Time Series-based information processing. This elasticity is achieved through AutoScaling groups for collection and processing, AWS data pipelines for Amazon Elastic MapReduce scheduled jobs, AWS data pipelines for inter-system data

dynamic Amazon EC2 instances. amazon CloudWatch monitors these servers, while AutoScaling manages them to automatically increase or decrease EC2 capacity based on load. In this example, an independent node is used to receive uploaded media content to reduce the load on the web site. 2. The uploaded original files are stored in Amazon Simple StorageService (
