redis transaction

Label:Originally intended to write about the transaction control process in the SSIS package, it was found that many of the basic concepts needed to be based on the isolation level of SQL Server transactions and transactions. So it took some time to get a good look at the concepts of transactions in SQL Server database, the ACID principle, the common problems in transactions, the causes of problems, and the level of

that corresponds to the transition from Redis to LUA:Lua boolean true Redis integer reply with value of 1/lua Boolean true converted to Redis integer 1 in replyThe following are examples of several types of conversions: > eval "return" 0 (integer) > eval "return {1,2,{3, ' Hello world!

First, design ideas: When Master and Slave are operating normally, Master is responsible for service, Slave is responsible for standby; When Master hangs out, Slave Normal, Slave takes over the service, has the Write permission, simultaneously closes the master-slave copy function; When Master returns to normal, the data is synchronized from the slave, the master-slave copy function is turned off after the data is synchronized, and the master is restored, while sla

As we all know, transactions have four major features: ACID. That is, atomicity, consistency, isolation, and durability. Four features Atomicity A
