30.2 network traffic optimization 1 At present, users are basically downloading the app through the network and updating the app version, reduce the size of the app, you can effectively reduce user consumption of network traffic. 2 at present, the league has supported the incremental upgrade app features, so that even if the app has 10M size, but if the changes are only 10K, using the incremental upgrade feature, users only need to download

partitioned tables1. Create a range partition tableUse the partition by RANGE clause to indicate the range partition, use the partition clause to identify each partition range, and the partition clause subordinate clause to specify the physical properties that are specifically used for the partition segment, and automatically inherit the properties of the underlying table if there are no overloads.Re-Modify the example above:CREATE TABLE Sales(Invoice_no number,Sale_year INT not NULL,Sale_month

in table tennis, the round-trip time represents the time required to travel between two athletes. Then you will start to clarify the problem.Part of the general operation of most network protocols is like playing table tennis. These "out-of-the-ball", assuming you want to, is to establish and maintain a network link session (sessions) required for two-way exchange of information (such as TCP) or to run a service request (such as HTTP). These messages are very little or no data transferred durin

Xargs and exec are the filters passed by commands. They capture the results of the previous command and pass it to the next command. Simply put: -Exec must be combined{}\;And {} indicates the Result \; Terminator of the previous query. This is a fixed method. Xargs must be combined with | to process files in batches at a faster speed.

, and is a well-functioning distributed system in addition to its very good performance. Redis Redis is a NoSQL database based on Key-value, which is very active in development and maintenance. Although it is a Key-value database storage system, it natively supports MQ functionality, so it can be used as a lightweight queue service. For RABBITMQ and Redis on-board and out-of-team operations, each execution 1 million times, every 100,000 times the execution time is recorded. The test data is divi
