return the desired column (actually, when we take a more common middle tier), tend to return all columns instead of certain fields, just as in ORM, as in NHibernate, JBoss, if a row has 10K, then the page will be added to the 10K*10*20=2M array allocation at the end of the process, That's not the point. Sometimes we need the most array to replicate. So in PHP, the reasonable way is to use the variable aft

Thank you You check if the actual available memory and disk quotas are sufficient Hello, you said the actual available memory is the Memory_limit value in php.ini, I have set to 128M, or other memory settings?

Kjframeforandroid Framework Project Address: https://github.com/kymjs/KJFrameForAndroid When we write the Android program, we will definitely use a lot of pictures. Then the compression of the image is naturally necessary. Why compress? I don't think it's important to stress that everyone will know this one when they first learn Android: We write applications that have a maximum memory limit, where Java programs and C programs (when the NDK calls) share this memory size, An oom (OutOfMemory) ex

this was done. But at that time the study center of gravity was placed on the file system, the energy is limited, there is no further access to information. Just in the process of practice to see the realization of multi-terminal, the author of a theory, suddenly dawned.Because the function of writing data to the display or our own implementation, as long as we organize the logic, to each terminal planning a different memory, in the call write function when writing to each terminal's own memory

100k compression rate is about 65%, in the 10k+ picture resources on the same very cow rub, when the picture resources less than 10k with the size of the picture decreases, gradually reduced.Later specifically in our APK file is compressed in this way again, the size of the APK file from 11.86M to 10.52M, the effect of the APK file reduction is still very obvious.SummarizeThe way to reduce the APK file is

scaling. RabbitMQ RabbitMQ is an open source message queue written using Erlang, which itself supports a lot of protocols: Amqp,xmpp, SMTP, STOMP, and because of this, it's very heavyweight and more suitable for enterprise-class development. The broker framework is also implemented, which means that messages are queued in the central queue before being sent to the client. Good support for routing, load balancing, or data persistence. Redis is a NoSQL database based on Key-value, which is very a

divided into 128Bytes, 512Bytes, 1K and 10K four different sizes of data. The experiment shows that when the data is compared with the RABBITMQ, the performance of the Redis is higher than that of the 10k,redis when the data is larger than the size of the queue, and the Redis shows very good performance regardless of the data size. And RABBITMQ's performance is much lower than Redis.ZeroMQZEROMQ claims to

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 divided into 128Bytes, 512Bytes, 1K and 10K four different sizes
