The Fast Query Window is the window of time in which your queries are run against high-performance Primary Storage. Queries that you make inside the time range supported by Primary Storage fall within the Fast Query Window.
The Honeycomb Professional plan also includes additional storage for older events, backed by Secondary Storage. As events age out of Primary Storage, they are moved to Secondary Storage. The Community plan does not include Secondary Storage.
With the combination of Primary and Secondary Storage, you get faster query performance for your more recent data (within the Fast Query Window) while retaining the ability to query across longer retention timeframes as needed, on a per-dataset basis. This lets you decide which kinds of data need longer Fast Query Windows for faster performance, or larger Secondary Storage for greater retention.
The boundaries of the Fast Query Window are shown by the yellow bar in the time range selector.
Queries you make within the Fast Query Window are typically 5-10x faster than those that extend beyond it. You can query across the Fast Query Window boundary into Secondary Storage.
When you query across the boundary into Secondary Storage, results may be a little slower to return, but you don’t have to keep the current window open while the query is running. You can start a new query and find the previous query’s results in your history later.
If you are a team owner, you can configure storage for each of your datasets separately.
The combination of the two windows make up the Total Retention Period. For example: if you have 7 days of Fast Query Window retention, older data moves to Secondary storage for an additional 21 days, resulting in a Total Retention Period of 28 days.
To tailor the size of a dataset’s storage windows:
Click on a column name to sort by that column. Then, click Manage next to a dataset to see the provisioning sliders to rebalance/re-allocate the Fast Query Window size vs Secondary Storage for that dataset. When you’re finished, click Update. Your new window size settings will go into effect immediately. Pruning of data (if you’ve adjusted your overall dataset size/Total Retention Period downward) can take up to 15 minutes.
