Terabyte-sized caches.two. FeaturesThe main features are:1. Fast2. Simple3. Multiple Cache Policies4. Cache data has two levels: memory and disk, so there is no need to worry about capacity issues5. Cache data is written to disk during virtual machine restart6. Distributed caching can be done via RMI, pluggable APIs, etc.7. Listening interface with cache and cache manager8. Support multiple cache manager instances, and more than one instance of the c

The general program idea is to use the recursion to calculate how much space the directory occupies, and then the space to occupy the value of the text file, so long as the access to this TXT file to know how much space occupied, do not have frequent access to read disk, save resources. Each time a user uploads a file or deletes a file, it is then counted again. Of course, you can also save the results to the database. Copy Code code as follows: function Countdirsize ($dir) {

the Host (Advanced) Collateral is an important feature of smart contracts that are different from other cloud storage platforms. It ensures that the hirer can retrieve the data at any time and regulates the behavior of the space supplier. There are three proper nouns, "collateral budget", "Maximum collateral" and "collateral". When the contract is established, the supplier is required to use the smart contract coin as collateral to enter the contract. The system will then return the collatera

knowledge, but these ideas have been talked about less. I personally think that clustering data processing is still a good optimization method, of course, can be used to solve the problem of clustering, but also to consider the Index organization table or table by clustering key reconstruction to get a similar effect, only the cluster data processing by the database at the bottom of a more reasonable. As for the high-speed data return is more suitable for the traditional C/s architecture data d

For example, (parted) set 1 boot on sets the boot tag of the partition numbered 1 to the on (effective) unit (set unit) format: unit: Select a unit that indicates the disk size for Parted. After that, all the numbers about the disk location (such as the start position of the partition) use this unit, and you don't need to give the unit suffix. (For example, if you select MB as the unit, 512 represents 512 MB, and you don't need to add mor
