A brief description of the experiment that the H3C simulator Wvrp5.2a does not support sub-interfaces: There is no configuration information in it. I have pasted the configuration information behind the article, if you are interested, you can stick it to the corresponding device to achieve the experiment effect.1. The first figure is your topology. This is my own figure. The vswitches are connected to the three routers respectively. I have noted the a

Why divide the table:When the data of a table reaches tens of millions of, the time you spend querying is much more, and if you have a joint query, I think I might die there. The purpose of the sub-table is to reduce the burden on the database

First, the preparatory work1. Prepare three databases: Db0, DB1, DB22.

Regular Expressions, grouping, submatching (sub-mode), non-capturing sub-matching (sub-mode), and regular expression capturing We know that the regular expression has a lot of characters to indicate the number of matches (quantifiers), which can be used to repeat the number of times of a single character. Sometimes, we may need to match the number of times multip

1. Maximum child segments and Problems Problem definition:For the given sequence A1, A2, A3 ...... An. Find a continuous sub-segment of the sub-segment to maximize the sum. For example (-,-,-5,-2) the maximum child segment is {11,-} and its sum is 20. (1) Enumeration Method The concept of enumeration is as follows: Start with a [0]: {A [0]}, {A [0], a [1]}, {A [0], a [1], A [2]}... {A [0], a [1],... A [n]}

reason is the performance problem:(1) In order to obtain better performance, often according to different databases to adopt a unique optimization method, even the DAO layer all with Hibernate Implementation, migrating the database is not easy to work. (2) using Hibernate to process associations often loads large amounts of data into business system memory, rather than processing them in the database system, but returning the final result. This undermines the decoupling of the production system

Need to be used in conjunction with Hintshardingstrategy.Because of the flexibility of the algorithm, the standard way is through the implementation of specific Java interface is the implementation of specific sharding algorithm such as Singlekeydatabaseshardingalgorithm, there are many cases, the Shard is relatively simple, such as purely customer number, In this case, an

consideration, we introduced a weighted load balancer, that is, within our system through a certain interface, each DB server can be assigned a weight, and then run the LB according to the weight in the cluster, a certain proportion of the load allocated to the DB server. Of course, the introduction of this concept has undoubtedly increased the complexity and maintainability of the system. There must be something lost, and we have no way to escape. T

such data to tables in different databases? We can do this by putting user_id all the article information in the 1~10000 into the article table in DB1, user_id all the article information in 10001~20000 into the DB2 table, and so on, until article. In this way, the article data is naturally divided into various databases, to achieve the purpose of data segmentation. The next problem to solve is how to find a specific database?
