Microservices mode (微服务模式) - Logs

The microservices deployment mode instantiates components of Loki as distinct processes. Each process is invoked specifying its target:

• ingester
• distributor
• query-frontend
• query-scheduler
• querier
• index-gateway
• ruler
• compactor

Running components as individual microservices allows scaling up by increasing the quantity of microservices.
