Redis as secondaryStorage generate a lot of client connection to my redis server

Hello, i have setup my redis client inside auth.ts to use it as a secondaryStorage, i have added inside my code a small redis.on("connect",... to log when a redis client is created, and i have see that at each new page who use auth there is a dedicated redis client. (I have 6 pages, in my redis i can see 8 connection (next -> 6, me -> 1, backend -> 1) Does i have this because i have a wrong better auth setup or something like that ? My code : 
/* Some dependancies */
const prisma = new PrismaClient();
const redis = createClient();
redis.connect();
redis.on("connect", () => {
  console.log("Redis client connected");
});
redis.on("error", (err) => {
  console.error("Redis client error", err);
});
redis.on("disconnect", () => {
  console.log("Redis client disconnected");
});

export const auth = betterAuth({
  database: prismaAdapter(prisma, {
    provider: "postgresql",
  }),
  rateLimiting: {
    enabled: true,
    maxRequests: 60,
    window: 60,
    // storage: "secondary-storage",
    customRules: {
      "/sign-in/email": {
        window: 10,
        max: 3,
      },
    },
  },
  session: {
    storeSessionInDatabase: true,
    cookieCache: {
      enabled: true,
      maxAge: 60
    }
  },
    secondaryStorage: {
        get: async (key) => {
            const value = await redis.get(key);
            return value ? value : null;
        },
        set: async (key, value, ttl) => {
      console.log("Setting key in Redis:", key, "with value:", value, "and ttl:", ttl);
            if (ttl) await redis.set(key, value, { EX: ttl });
            else await redis.set(key, value);
        },
        delete: async (key) => {
            await redis.del(key);
        }
    }
});
/* Some dependancies */
const prisma = new PrismaClient();
const redis = createClient();
redis.connect();
redis.on("connect", () => {
  console.log("Redis client connected");
});
redis.on("error", (err) => {
