我正在尝试从Redis删除大量键(〜20M),并且出现错误 RangeError:由于过度的递归调用,最大调用堆栈大小超过了
我尝试在递归调用中使用 process.nextTick(),但仍然遇到相同的错误。

count = "100";
cursor = "0";
function scanRedis(key, callback){

redisClient.scan(cursor, "MATCH", key, "COUNT", count, function(err, reply){
    if(err){
        throw err;
    }
    cursor = reply[0];
    if(cursor === "0" && reply[1].length === 0){
        return callback(false, true);
    }else if(cursor === "0" && reply[1].length > 0){
        redisClient.del(reply[1], function(deleteErr, deleteSuccess){
            return callback(false, true);
        });
    }else{
        if(reply[1].length > 0){
            delCount += reply[1].length;
            //console.log(reply[1]);
            redisMulti.del(reply[1]);
        }
        redisMulti.exec(function(deleteErr, deleteSuccess){
            process.nextTick(function(){
                scanRedis(key, function(err, reply){ //getting an error here
                    callback(false, true);
                });
            });
        });
    }
});
};

最佳答案

我通过在process.nextTick()函数的回调中插入另一个scanRedis()来解决此问题,它对我有用。

redisMulti.exec(function(deleteErr, deleteSuccess){
  process.nextTick(function(){
    scanRedis(key, function(err, reply){
      process.nextTick(function(){
        callback(false, true);
      });
    });
  });
});
