Time:09-25
The great spirit is good, I now have a problem, want to oracle in hundreds of millions of data need to index points now area very slow, I still have what way to improve the speed? At present all partitions in a table space, the speed of the first after have 2 w to 10 million per second per second only 23000
This is my create table statements, are now in a table space
I use the merge into the method of inserting (almost) and insert into efficiency Mergeinto statement below
Vc_bf_foid and vc_df_foid index index was made in the field is a must, because in addition to the insert need to do the update operation in these two fields, The great spirit returns busy, this problem bothering me for a long time, various tests are slow
