Ioredis hincrbyRedis overview Redis là gì? Redis là tên viết tắt của Remote Dictionary Server (Máy chủ từ điển từ xa), là một phần mềm mã nguồn mở được dùng để lưu trữ một cách tạm thời trên bộ nhớ (hay còn gọi là cache data) và giúp truy xuất dữ liệu một cách nhanh chóng.Redis hash는 1개의 key에 n개의 field, value를 저장할 수 있습니다. 이 때 저장 가능한 최대 field는 약 40억개 정도 입니다. Every hash can store up to 232 - 1 field-value pairs (more than 4 billion) 2-1.
