pim data synchronization

Due to the recent project needs, synchronization of cloud server data to the * * side to make big data analysis. Ideas: Initially, as long as the data is synchronized, prepare an Open data acquisition interface. But the real-time is poor, there will be delays. Th

How to improve performance in data processing-introduce concurrency but avoid synchronization background As long as there is a database, there will be a need to process data in batches in the background, such as data table backup, regular cleaning, data replacement, and

failed to synchronize the files as long as set. 5, Sersync with crontab function, just open in the XML configuration file, you can according to your request, the whole synchronization of a period of time. No additional configuration of the crontab feature is required. 6, Sersync socket and HTTP plug-ins to expand, to meet the needs of two times development. Visible Sersync + rsync is more efficient than Inotify-tools + rsync

CDC implements data synchronization and incremental updates In sqlserver2008, CDC is used to track data updates. Compared with the previous time stamp, triggers are more convenient and convenient.

Unison Introduction: two-way image synchronization tool that supports cross-platform synchronization. Unios can keep the content consistent between the two folders on the local disk and synchronize network data. Features: cross-platform 1. No special requirements on kernel and User Permissions 2. Unison is bidirectional and can automatically update the two copies

This article by show according to Lin Feng to provide friendship sponsorship, starting in the mud row world. In the previous article we described how to use rsync synchronization files, this article we will introduce, how to integrate rsync and inotify to achieve real-time data synchronization. To achieve this goal, we need to take the following steps: 1, the adv

Because you need to configure the master-slave synchronization configuration of MySQL, the configuration process is now recorded and is not required in the future. MySQL DATA Master/Slave synchronization 1.1. Synchronization Introduction The master-slave synchronization of

Original: SQL Server replication-publish subscription (SQL Server data Synchronization)SQL Server synchronization is achieved through SQL Server's own replication tool, with 2 major strides in sub-publishing and subscription.A, copy-publishBefore publishing, you need to set several preconditions, publish properties, and snapshot locations. The main issue is to se

First, rsync1. What is rsyncRsync is a remote data synchronization tool that enables data synchronization within or across hosts. With the service runtime listening on the TCP 873 port, the rsync algorithm can reach only the part of the file change, not the entire transmission, so the speed is quite fast, good performa

The formal approach to data synchronization is to useSQL-ServerBut copying is a little tricky here. From the very beginning, considering the size of the client database and other requirements of the clientMSDEInstall oneSQL-ServerIt is a waste of resources. Considering that the technology of binding to the database platform is not a good choice for the future application of the system. More importantly, in

The article "Data Synchronization Algorithm Research" proposes an improved data synchronization algorithm. Based on the implementation of the prototype system, extract key algorithms such as file splitting, differential encoding, and file synchronization and package them int

Well, this is the beginning of the article said that the number of threads to get the value fields are 2, and then each +1 after the

Using rsync + inotify for data synchronization I. What is rsync? It is a tool for file synchronization and data transmission in Linux. it uses the rsync algorithm to synchronize data between the client and the server, and between the master server and the backup server. Rsyn

Label: MongoDB data migration and synchronization of MONGODB data replicationMongoDB requires a minimum of two instances of replication. One is the master node master, which handles client requests and the rest is slave, which is responsible for replicating data from master. Master Write Processing:Master is respon

Rsync + inotify for data synchronization and FAQs Rsync: Remote Sync is a data image backup tool for Unix-like systems. Rsync can be used to back up data with low real-time requirements. For example, you can use the specified backup file server to back up data to the specifi

The multi-machine data synchronization mechanism Unison + inotify-tools was accidentally encountered in the QQ group this morning when I heard a problem about two-way Real-Time Synchronization of different machines. When I thought of it, I found that the database (mysql ), it seems that the two-way real-time synchronization
