details. BRIN indexes (Block Range INdexes) use much less space in disk compared to a standard b- tree index for very large tables whose columns have some natural correlation with their physical location the CREATE AGGREGATE command. You can now use the CLUSTER command on append-optimized tables over B-tree indexes. The SELECT SQL command now supports the SKIP LOCKED option. The new command IMPORT FOREIGN query engine model, where the execution engine takes an execution plan and uses it to generate a tree of physical operators, evaluates tables through physical operators, and delivers results in a query

Database returned wrong results for a query because it chose an incorrect motion type during plan tree iteration. 12482 : Reinstates the Greenplum Database-specific --wrapper and --wrapper-args options The storage needed for the merge join key was incorrectly allocated on the inner side of the plan tree. This led to a SIGSEGV when executing the sort node of the inner side of the merge join. The problem to use the join key are provisioned with the right amount of storage, leaving the rest of the plan tree intact. 31090 - Storage: Segment Mirroring : pg_rewind was updated to reduce the number of lstat

distributed across the segment hosts as is table data. The default index type in Greenplum Database is B-tree. Because index size depends on the number of unique values in the index and the data to be inserted index is impossible. However, you can roughly estimate the size of an index using these formulas. B-tree: unique_values * (data_type_size + 24 bytes) Bitmap: (unique_values * number_of_rows * 1 bit * compression_ratio loading data into a table. After the load, re-create the indexes for the table. Create selective B-tree indexes. Do not create bitmap indexes on columns that are updated. Avoid using bitmap indexes for
