batchSet

写入一批数据

  1. /**

  4.  * @param {Array}       argsArray
  5.  *        {Buffer}      argsArray[i].hashKey      required

  7.  *        {Buffer}      argsArray[i].value        required
  8.  *        {Number}      argsArray[i].ttl          optional
  9.  *        {Number}      argsArray[i].timeout(ms)  optional

  11.  * @throws{InvalidParamException} callback is not function

  13.  client.batchSet(
  14.    tableName,  
  15.    argsArray, 
  16.    function(err, result){
  17.      // err will be always be null, result is {'error': err} array
  18.      // if batchSet[i] operation succeed, result[i].error will be null
  19.      // else result[i].error will be instance of PException

  • batchSet操作的必填参数为表名，hashKey-sortKey-value对象数组和callback
  • callback的err总是为null，result[i].error表示第i个set操作的出错情况
