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: sdw16: $ Du-SH/gpdata {1, 2}/data/GP * 347g

Today's world is an information-based world, our life, whether it is life, work, learning can not be separated from the support of information systems. The database is the place behind the information system to preserve and process the final results. Therefore, the database system becomes particularly important, which means that if the database is faced with a pr

How to synchronize some configuration tables to GP library issues from Oracle database during the daily production process of the system.First, the way you used it before:0. Export plain text format from Oracle using 3rd party tools and store locally;1. Loading the library with the GP external tableThe advantage of this approach is that the performance is very high for a table that needs to synchronize large amounts of data, the disadvantage is a bit
