visible，如果不可见，显示 committed。 txnld 为这个 insert 对应的导入事务的 id。 err 字段会显示一些其他非预期错误。 当需要查看被过滤的行时，用户可以通过如下语句 show load where label="xxx"; 返回结果中的 URL 可以用于查询错误的数据，具体见后面 查看错误行 小结。 数据不可见是一个临时状态，这批数据最终是一定可见的 可以通过如下语句查看这批数据的可见状态： from tbl2 where k1 = "a"; ERROR 1064 (HY000): all partitions have no load data. url: http://10.74.167.16:8042/api/_load_error_log?file=__shard_2/error_log_insert_stmt_ba8bb9e158e4879-ae8de8507c0 b9e158e4879_ae8de8507c0bf8a2 其中 ERROR 1064 (HY000): all partitions have no load data 显示失败原因。后面的 url 可以用于查询错误的数据： show load warnings on "url"; 可以查看到具体错误行。 ### 2. 超时时间 INSERT 操作的超时时间由会话变量 query_timeout

-> workers) • Bins are selected uniformly at random - At the end of the process, the maximum load is $\Theta(\ln n/\ln \ln n)$, with high probability • Instead, we select d destination bins, each ball at the least full bin: • when d=2, the maximum load is $ \ln \ln n / \ln 2 + O(\tau) $ , with high probability • when d>2, the maximum load keeps decreasing, but only by a constant factor ## Dynamic Dynamic resource allocation • Choose one among n workers • check the load of each worker and send the item to the least loaded one • load checking for every item can be expensive • Choose two workers at

to it by declaring it as global x. This prevents name conflicts for global's initialized after load time. The syntax M.x = y does not work to assign a global in another module; global assignment is resolve to the definition of that variable in ModuleName. To load a module from a package, the statement using ModuleName can be used. To load a module from a locally defined module, a dot needs to be added module name like using .ModuleName. To continue with our example, julia> using .NiceStuff would load the above code, making NiceStuff (the module name), DOG and nice available. Dog is not on the export
