批量时使用Lists.partition(list,num) 场景:当我们通过一堆ID,批量查数据库,并写入文件时,oracle数据库的 in(xx,xx,xx,xx..)里面的个数不能超过1000,超过1000则会报错,我们就可以批量去做这件事; publicstaticvoidmain(String[] args) { List<String> list =Lists.newArrayList();for(inti = 0; i < 21...

以list字段为分区关键字段，进行分区。
在split partition时，如果所有索引都是local index并且新split出来的partition为空时，oracle不需要rebuild index，这就是fast split。但是当新的partition非空时，则index处于unusable状态，需要rebuild index。而在rebuild index这段时间内，如果有SQL进来，就会出问题了。oracle并没有给出一个安全的split ...
