When the MySQL data volume is too large, it will face pressure decomposition, then the sub-database table is a good solution, and now we have to talk about how MySQL library sub-table is ideal, and then use PHP how to invoke.1, master-slave replication, read/write separationTo modify the data for the main library, the query is used from the library. A master multi-slave, to reduce the database read pressure

only the language for embedded systems and mobile terminals. Of course, users can customize each of the weights in the list, or they can use the list's pre-set evaluation scheme.The default presets in the list are set according to the average interest weights of the IEEE members, so what are the top ten programming languages in the 2016 spectrum?After two consecutive years in the second runner-up, C language has finally replaced the Java top position

The TIOBE December 2014 programming language rankings show that the R programming language is affected by big data, the industry is sought after, the market share once climbed to the top 12, and last year 38, R language is expected to be the candidate for this year's TIOBE year language.R language is God horse East?

You can use the following command to export a "naked warehouse" and then use the SCP command to copy them to your server:$ git clone --bare /home/user/myrepo/.git /tmp/myrepo.git$ scp -r /tmp/myrepo.git myserver.com:/opt/git/myrepo.gitIf other people also have an SSH account on the myserver.com server, TA can clone the (clone) code from this server:clone myserver.com:/opt/git/myrepo.gitThe above command will prompt you to enter the SSH password or use the public key.Viii

transaction. (execution is performed by MySQL's master thread threads.) The redo log buffers are written to the disk's redo log file (REDO log) every second in the main thread. Whether the transaction has been committed or not. The default log file is Ib_logfile0,ib_logfile1 When set to the default value of 1, log buffer is written to the log every time a transaction is committed. If set to 2, each COMMIT transaction writes a log, but does not perform the brush operation. The log file i
