merge

The merge method vertically stacks all constituent tables of a PartitionedTable to produce a new table in the same way that merge vertically stacks a list of tables.

Syntax​

merge() -> Table

Parameters​

This method takes no parameters.

Returns​

A new table containing the contents of all of the constituent tables of a PartitionedTable.

Example​

In the following example, the source table is partitioned by IntCol, which has 3 unique values. Thus, partitioned_table has 3 constituent tables. Merging partitioned_table into result shows that result contains all of the same contents as source, but in a different order. Partitioned tables get merged based on the order of the constituent tables.

from deephaven import empty_table

source = empty_table(10).update(["IntCol = i%3", "StrCol = `value`"])
partitioned_table = source.partition_by(["IntCol"])

result = partitioned_table.merge()
