1. Industry SurveyThe index system needs to get all the document information through the main query, a simple implementation is the entire table of data to memory, but this may cause the entire table is locked, and other operations are blocked (for example: insert operation on the MyISAM). At the same time, a lot of memory is wasted to store query results. Like it's the problem. In order to avoid such a situation. Coreseek/sphinx supports a technique called section query. First, Coreseek/sphinx

We can perform full backup for a small number of databases every day, because it does not take much time. However, when the database is very large, we are unlikely to perform a full backup every day, in addition, it is changed to a weekly full backup, and an incremental backup every day is similar to

Table mode: export (import) All or specified tables of the user;C. entire database: export (import) all objects in the database.For example:Normal exportA.

The incremental design in Vivado will reuse existing layout and routing data to reduce uptime and produce predictable results. When the design has more than 95% similarity, the running time of the incremental layout will be twice times shorter than the average layout route. If the similarity is less than 80%, the use of incremental layout is only a small advantag
Usage type: the system load is concentrated in a certain period of time, such as 8 hours during the day, and is usually idle at night. Therefore, data can be backed up at night.

The problem with a full backup is easy to see, every time the data content is backed up, there is a large amount of duplicate data in the backup data, and full backup time and recovery time is very long.

And can be dynamically loaded through the Resources.load method. This is usually the development is commonly used in the load of resources, but the disadvantage is that the resources are packaged directly into the game package, can not do incremental updates.

Background:In Web applications, we often use black and white lists. However, we cannot always request a full amount, and the network and database will be exhausted. So here we design a cache mechanism for incremental requests. Full requests provide update of the low frequency of the blacklist and whitelist, and incremental requests provide update of the high frequency of the blacklist and whitelist. Of cour

Both iterative and incremental models belong to the software life cycle model developed in parallel, but these two models are often confusing or hard to understand. Next we will introduce the differences and similarities between the two models.Iteration cannot be parallel. Iteration parallelism refers to iteration tasks.
