scenario, page click statistics, similar to Baidu statistics;
Flume gets the most basic click information of the log;
storm bolt fills click information (some minor information processing);
but does not know what to do in the end, bolt directly into the mysql library before; but with the sharp increase in the number of clicks, mysql can hardly read and write, so I wonder if it is possible to add a cache or something in the middle.
for example, storm-"redis -" mysql, asks for divine guidance.
