business uses the hardware netapp/emc and san optical fiber architecture. for resource data storage and video, sas or solid state ssd disks are used. if the data is too large, you can use the hot spot Shard method, for example, the most frequently accessed 10-20% uses ssd storage, and the 20-30% in the middle uses the sas disk, the last 40-50% can use cheap sata. Layer 7: If the design of tens of millions

the form of a chart, we can make a new year's annual plan based on that data. Without making a decision on the forehead. And now the application of data visualization is also very much, the actual application also shows the corresponding value.Say the above three points, and then say big data technology.The first thing to mention is Hadoop, a distributed storage that is now in use in most enterprises, while its distributed storage shortens the user's read time. Next-generation technology, spark

Parameters Create flashcache: flashcache_create-B 4 k cachedev/dev/sdc/dev/sdb The size of the flashcache block is the same as that of the Percona page. Flashcache parameter settings: Flashcache. fast_remove = 1: Enable the fast remove feature. when the machine is disabled, you do not need to write dirty blocks in the cache to the disk. Flashcache. reclaim_policy = 1: dirty block flushing policy, 0: FIFO, 1: LRU. Flashcache. dirty_thresh_pct = 90: dirty block threshold value on each hash set in

= re.compile(p1)print pattern1.findall(key)Output results[‘@hit.‘]Added a "?" We changed the greedy "+" to the lazy "+". This is also true for [abc]+,\w* and the like]. Quiz: The above example can not use lazy match, think of a way to get the same result * * Personal advice: When you use the "+", "*", you must first think about whether the greedy type or lazy type, especially when you use a larger range of items, because it is likely to be more matching characters back to you!!! *

SSD interface is diverse, the mainstream SATA3.0 interface most common, the recent very hot M.2/PCI-E interface, once extremely the SSD most loves to use the mSATA interface, now has appeared a u.2 interface, must pedal m.2, replaces Sata, becomes the future SSD mainstream choice? What exactly is the U.2 interface? Today's SSD story, we'll talk about u.2 SSD. 　　What is the U.2 interface? The U.2 interface, formerly called SFF-8639, is driven by Intel single-handedly.

more times. But we didn't dwell on how many times it was. So it will be as "greedy" as possible to give us matching characters, in this case it matches to the last ".". How do we solve this problem? Just add one after "+"? "Just fine." Import re key = r "chuxiuhong@hit.edu.cn" p1 = r "@.+?\." #我想匹配到 @ back to "." Between that here is hit pattern1 = Re.compile (p1) print Pattern1.findall (key) Output results ['@hit.'] Added a "?" We change the greedy "+" to the lazy "+". This is

/blog_65efeb0c0100htz7.html Common normal test methods for SPSS and SAS Many analytical methods of measurement data require that the data distribution is normal or approximate normal, so it is necessary to test the original independent data for normality.By plotting the frequency distribution histogram of the data, the normality of data distribution is qualitatively judged. Such a graphical judgment is by no means a rigorous test of normality, and the
