Change of architecture, refactoring of working code in order to ensure processing of 7000 requests per second Tasks:

• queue unloading (service refactoring - to exclude reconnection for each request, replacing requests through queues with requests via the http interface, transferring part of the queues from rabbitmq to redis)
• unloading queries to the database (refactoring services to exclude reconnection for each query, narrowing the number of services that need data from the database);
• creating a limiter that limits the number of requests to social networks;
• the transition from creating a whole set of services for one user to single services for all users;
• removing unnecessary services and combining them into one
• speeding up queries from UI
• Elimination of message loss during queue drop.
