NET Series courses (vi) SOLR timing incremental indexing and securityThe way that SOLR increments the index is an HTTP request, but the request obviously does not meet the requirements, we need an automatic incremental index, SOLR officially provides a timer instance to complete the incremental index,First download apache-solr-dataimportscheduler-1.0.ja
There's a lot of information on the web that doesn't make it clear whether the log switch is a full checkpoint or an incremental checkpoint. Some say it's a complete checkpoint, and some say it's an increase. Quantity Check point. In fact, if you have a deep understanding of the difference between a full checkpoint and an incremental checkpoint, you should know whether the log switch is an
MySQL Incremental backup A small number of databases can have a full backup every day because it won't take much time, but when the database is large it is unlikely to make a full backup every day, and you can use incremental backups. The principle of incremental backup is to use MySQL's Binlog log. 1, first do a full backup: The code is as follows

Label:MySQL database is commonly used by the mysqldump export SQL for backup, but not suitable for a large number of databases, speed, lock table is two serious problems. I wrote the previous article about Xtrabackup's hot spare tools, see http://www.linuxidc.com/Linux/2015-02/113058.htm. The following script is the ability to automatically back up a database based on the Xtrabackup implementation. Requirements Description: A full backup of the database is done 23 o'clock every night.

Intended audience This article is tested in linux and mysql 4.1.14. After modification, it may be applicable to mysql 4.0, 5.0 and other versions. This article is applicable to mysql that does not enable replication. If replication is started, you may not need to adopt this backup policy or modify relevant parameters. Each person may have different backup policies. Therefore, Please modify the policies based on actual conditions to avoid copying them, which may cause unnecessary losses. I hope y

Guidance: I am a php Cainiao, and my company's business is not complicated, but recently I used full-text search, so I wanted to use sphinx. There are roughly three parts: 1: installation; 2: 3: api call. This section describes how to configure and call APIs. I previously wrote a separate post to check the install
in the previous article we introduced the full-volume update SOLR index, but when the volume of data is large, frequent updating of the index will consume system performance, if the update frequency is low, it will affect the short-term data accuracy, so the interval of the update time is difficult to define. Incremental indexing solves this problem, we can only update those changes in a short period of time, so as to avoid a large number of data upda

Introduction of CDCUsually in the case of a small amount of data, when we load all the data from one data source into the target database, we can take the following policy: first, the target database's data are all emptied out, and then all re-loaded from the data source. This is one of the simplest and most intuitive and error-prone solutions, but in many cases it can cause performance problems. If our data source comes from different business systems, the data is millions, tens of billions of
Differential backup: Back up data based on full backup. Because the tar command cannot implement differential backup, this article explains how to use the dump and restore commands. Of course, the dump and restore commands can also implement full backup and Incremental backup. 1.

many Oracle beginners have headaches due to the checkpoint knowledge point. The vast majority of Oracle documents describe full checkpoints and incremental checkpoints; for example, if the switching of online logs results in a full checkpoint or an incremental checkpoint, there is a lot of debate. In fact, there is a significant difference between an incremental

Full backupThe most common and simple backup is to directly use the copy command to copy the version library directory to the backup directory. However, this is not a safe method, because if the version library changes during the copy process, the backup results will be inaccurate and the backup function will be lost, therefore, subversion provides the "svnadmin hotcopy" command to prevent this problem. Do you still remember our version library directory? D:/svnroot├ ── Project1│ ─ ── Conf│ ├ ──
There is a common scenario where the entire dataset is so large that it is difficult to rebuild the index on a regular basis, but each new record is relatively small. A typical example is a forum that has 1 million archived posts, but only 1000 new posts per day. In this case, a "near real-time" index update can be implemented using the so-called "primary index + Incremental index" (Main+delta) pattern. The basic idea of this approach is to set up two
