For example, if the total number of buckets in table is 32 and tablesample (bucket 3 out of 16) indicates that the data of two buckets (32/16 =) is extracted in total, data o

When selecting a product for deduplication, you 'd better consider the following ten questions. When a storage product provider releases a deduplication product, how can it locate its own product? Do you have to think about the following questions? 1. What is the impact of deduplication on backup performance? 2. Will deduplication reduce data recovery performance? 3. How will capacity and performance expansion grow with the environment? 4. How

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware

. It took him two days to submit the code after he finished the development and passed the test. Who knows their project manager, after reading the code, ran to his desk and patted him and said, "How did you learn the data structure? What database does this real-time queuing module use? Isn't it enough to complete it in the memory. Change it now. It must be completed today and handed over to me early tomorrow morning ." The food was so cold and sweaty
