Time has passed quickly, and it has been more than a year since the new company. In terms of technology, the scope has become wider, including the following major points:
(1) RPC service calls (products like DUBBO)
(2) Message middleware (products like metaq)
(3) Cache (memcached, redis and other products)
(4) Data monitoring (interface call volume, interface rt, application cluster rt and load, database rt and load, stand-alone application rt and load, etc.)
(5) Data migration (mysql binlog, etc.)
(6) Multi-active in different places (multi-unit deployment)
(7) Test framework
(8) Correction platform (for different errors, write different correction logic, write and use now, and integrate permissions and operation records)
etc
The business is very complex and there are many, but the learning of technology still has to test your usual accumulation.
