remove_blink
The remove_blink method returns a new non-blink copy of the source table or the source table itself if it is already a non-blink table. This is useful when you want to disable the default aggregation behavior of a blink table.
By default, many aggregations on blink tables are computed over every row that the table has seen since the aggregation was called. Although data in a blink table disappears every update cycle, some aggregations can still be computed as though the whole data history were available.
Syntax
table.remove_blink() -> Table
Parameters
This method takes no arguments.
Returns
A new non-blink Table.
Example
The following example creates a simple blink table and then calls remove_blink to make it a non-blink table. We then demonstrate the difference in aggregation behavior between a blink table and a non-blink table by summing the X column in each table.
from deephaven import time_table
t_blink = time_table("PT1s", blink_table=True)
t_no_blink = t_blink.remove_blink()
- t_no_blink
- t_blink
