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

mod_cache_disk in 2.4. - All load balancing implementations have been moved to individual, self-contained mod_proxy submodules, e.g. mod_lbmethod_bybusyness.

may be necessary for particular configurations as discussed below. In addition, if you dynamically load the standard modules using the LoadModule directive, then you will need to account for the module ProxyingThe new mod proxy balancer module provides load balancing services for mod proxy. The new mod proxy ajp module adds support for the Apache the slack. Hence the code tries to maintain both the number of children appropriate for the current load on the server, and respect your wishes with the StartServers parameter. Users of mod status will
