WSO2 ESB缓存中介以缓存配置文件
[英]WSO2 ESB Cache mediation to cache a config file
问题描述
I need to get some configs from a my xml config file. 
我需要从我的xml配置文件中获取一些配置。 Due to the high load it is a bad idea to read data from file for each proxy service invocation. 由于高负载，对于每次代理服务调用，从文件中读取数据都是一个坏主意。 I found smooks and cache mediators and I think these two mediators can help me but I don't know how. 我发现了欺骗和缓存中介器，我认为这两个中介器可以帮助我，但我不知道如何。 Also I've heard of VFS transports but since I have the large scale and high load of requests I have to reduce the service invokation or reading from files and handle this problem with some cached data in server RAM. 我也听说过VFS传输，但是由于请求量很大且负载很大，因此必须减少服务调用或从文件中读取数据，并使用服务器RAM中的某些缓存数据来处理此问题。

How about using a database to build a persistent cache, so that you can do a dblookup before reading the file. 如何使用数据库构建持久性缓存，以便可以在读取文件之前执行dblookup。 This mediation logic can be defined within the ESB where the ESB will do a DBlookup before accessing the file. 可以在ESB内定义此中介逻辑，其中ESB将在访问文件之前执行DBlookup。 Similarly for a new entry you can create a cache entry in the DB. 同样，对于新条目，您可以在数据库中创建一个缓存条目。
