iqtest dk

In the previous article, I wrote how to use gp_segment_id to determine whether the Dk value of the table has data. The following describes how to check the allocated unbalanced table by checking the amount of space occupied and re-adjust the Dk value. One of my greenplum machines, one of which has more data volumes than other nodes, shows the imbalance of data distribution, as shown in the following example

To test whether multi-Table association can be filtered by Image segment when multiple DK distribution keys exist, the test is as follows: [gpadmin @ gtlions50 ~] $ Psqlgtlionspsql (8.2.15) Typehelpforhelp. gtlions # createtablegtt1 (idint, namecharactervarying (5) distributedby (id, name); CREATETAB To test whether multi-Table association can be filtered by Image segment when multiple DK distribution keys

Log Analysis of ETL background system data is currently underway. You can view the tasks that have been running for a long time, find the jobs that have consumed a long time, and optimize the logic and database layers. this article focuses only on Database optimization (including SQL statement adjustment and greenplum table DK adjustment ). view a job that takes about 30 minutes, find the corresponding source table, and perform the following analysis:

Qian yongchao, a netizen, sent an email saying that he was reading a book named outliers. When talking about iqtest in the book, the author mentioned Raven'sProgressiveMatrices test method. This is a series of questions from easy to difficult, generally with 48 questions. To illustrate how difficult this test can be, the author gives the last question of the entire test, even if the author does not know how to do it. I searched the internet and confir

Hill sort is also known as narrowing the incremental sort, this sort method first groups the whole unordered sequence, set the size of each group is the grouping Factor DK. After the completion of the group, the first and the I+DK, I+2DK, i+3dk ... Element is a group. You can then sort the group in some way, using the insert sort.After each group is ordered, a sequence of "ordered" sequences is obtained. Th
