The number of Redis slots is 16384 for the following reasons: distribute data evenly to avoid data skew. To ensure high data availability, even if a node goes down, its slots will be transferred to other nodes. Easy to scale, dynamically add or remove nodes and reallocate slots based on data volume. Compatible with older Redis versions ensuring backward compatibility. Fast search, high memory efficiency, data key space consistency.
The reason why the number of Redis slots is 16384
Redis stores data in slots called slots In the internal data structure, each slot contains a part of the key space. In order to ensure uniform distribution and high availability of data, Redis uses a sharding mechanism to allocate slots to different Redis nodes.
The selection of the number of slots takes into account the following factors:
Other Benefits:
In addition to the above reasons, 16384 slots also provide the following benefits:
Therefore, the number of Redis slots is 16384, which is the best choice based on comprehensive considerations such as uniformity, availability, scalability, compatibility, and memory efficiency.
