Writing Data

The standard method for inserting a new data point is through the db.insert(...) method. To insert more than one Point at the same time, use the db.insert_multiple([...]) method, which accepts a list of points. This might be useful when creating a TinyFlux database from a CSV of existing observations.


TinyFlux vs. TinyDB Alert!

In TinyDB there is a serious performance reason to use db.insert_multiple([...]) over db.insert(...) as every write in TinyDB is preceeded by a full read of the data. TinyFlux inserts are append-only and are not preceeded by a read. Therefore, there is no significant performance reason to use db.insert_multiple([...]) instead of db.insert(...). If you are using TinyFlux to capture real-time data, you should insert points into TinyFlux as you see them, with db.insert(...).


>>> from tinyflux import Point
>>> p = Point(
...     measurement="air quality",
...     time=datetime.fromisoformat("2020-08-28T00:00:00-07:00"),
...     tags={"city": "LA"},
...     fields={"aqi": 112}
... )
>>> db.insert(p)

To recap, these are the two methods supporting the insertion of data.



Insert one Point into the database.

db.insert_multiple([point, ...])

Insert multiple Points into the database.
