Service performance (OLTP benchmark) originally sysbench was mainly written for mysql benchmark. But now SysBench will be further extended to support more database backends, distributed benchmarks and third-party plug-in modules. Sysbench starts threads according to the specified number. each thread establishes a connection with mysql. each thread continuously performs transaction operations, opens transactions, and then performs query, update, and i
At this year's TechEd conference, Microsoft announced the first technical preview version of SQLServer2014, which will be officially available for download this month. The official release date of the product is initially set at the end of this year. The biggest highlight of the new version is the table-level memory OLTP (On-LineTransactionProcessing, online transaction processing system) and real-time big data analysis. At this year's TechEd conferen
In practical work, often hear beginners say: "Large table partition can certainly improve query performance." In fact, when you do not understand the application of the situation, blind to create a partition not only can not improve query performance, but also may lead to query performance degradation. Therefore, before deciding whether to use a partition, you must understand the current application environment. Generally speaking, the application of database is divided into two kinds:

Application Scenarios: The main application scenario: Database data subscription between the departments or across the computer room. Similar products have Ali's canal. Supports Oracle and MySQL databases. Databus and canal, data is based on database log mining. My previous blog also mentions that today's data processing can be broadly divided into two categories: online transaction

For DSS Systems Pga_aggregate_target = (In other words, for a simple database server, we usually need to keep 20% of the physical memory for the operating system, and the remaining 80% can be allocated to Oracle for use. The memory used by Oracle is divided into two parts, the SGA and the PGA, so the PGA can occupy the 20% (OLTP system) to the 50% (DSS system), which

system optimization target is not the same. In general, we divide the system into two main categories: OLTP and OLAP, also called DSS. OLTP is the full name of an online trading system, such as our receiving online system. This type of system is characterized by a very frequent transaction, but with very little data involved in each transaction. The database response time requirements are relatively high,

On the storage overhead of the cache, we can gain useful performance benefits in the face of chatty network traffic similar to the database
