Create a table with timeTable
This guide will show you how to create a time table. A time table is a special type of table that adds new rows at a regular, user-defined interval. Its sole column is a timestamp column.
Here, we will make a simple time table that ticks every two seconds. We are using the time_table
method. Its sole argument specifies the interval at which the table ticks.
Copy and run the following code in your console:
from deephaven import time_table
result = time_table('00:00:02')
note
The ticks used around the time representation above are single-quotes (‘), not backticks as used around strings (`).
This produces a table with one column (Timestamp
) that appends a new row every two seconds.
Time tables are often used as trigger tables, which can:
- reduce the update frequency of ticking tables
- create the history of a table, sampled at a regular interval
