Brief introductionMongoDB is more like MySQL, support field index, cursor operation, the advantage is that the query is more powerful, good at querying JSON data, can store large amounts of data, but does not support transactions.MySQL is

In many cases, when we crawl the site using WebMagic, the crawled data is expected to be stored in MySQL and Redis. Therefore, it needs to be extended to implement a custom pipeline. First, let's look at the four basic components of webmagicFirst,

Two persistence mechanisms of RDB and AOFRdb:snapshot---the stored format is in binary format, is the default persistence mode, and periodically saves data from memory to disk by a pre-defined policy: Data file defaults to Dump.rdbSo there are two
