You need to have write permission on the collection to be able to ingest data.

Check out the examples below for common scenarios of ingesting data into a collection.

​
Dataset schema

Tilebox Datasets are strongly typed. This means you can only ingest data that matches the schema of a dataset. The schema is defined during dataset creation time.

The examples on this page assume that you have access to a Timeseries dataset that has the following schema:

Once you’ve defined the schema and created a dataset, you can access it and create a collection to ingest data into.

from tilebox.datasets import Client

client = Client()
dataset = client.dataset("my_org.my_custom_dataset")
collection = dataset.get_or_create_collection("Measurements")

​
Preparing data for ingestion

collection.ingest supports a wide range of input types. Below is an example of using either a pandas.DataFrame or an xarray.Dataset as input.

​
pandas.DataFrame

A pandas.DataFrame is a representation of two-dimensional, potentially heterogeneous tabular data. It’s a powerful tool for working with structured data, and Tilebox supports it as input for ingest.

The example below shows how to construct a pandas.DataFrame from scratch, that matches the schema of the MyCustomDataset dataset and can be ingested into it.

import pandas as pd

data = pd.DataFrame({
    "time": [
      "2025-03-28T11:44:23Z",
      "2025-03-28T11:45:19Z",
    ],
    "value": [45.16, 273.15],
    "sensor": ["A", "B"],
    "precise_time": [
      "2025-03-28T11:44:23.345761444Z",
      "2025-03-28T11:45:19.128742312Z",
    ],
    "sensor_history": [
      [-12.15, 13.45, -8.2, 16.5, 45.16],
      [300.16, 280.12, 273.15],
    ],
})
print(data)
Output
                   time   value sensor                    precise_time                      sensor_history
0  2025-03-28T11:44:23Z   45.16      A  2025-03-28T11:44:23.345761444Z  [-12.15, 13.45, -8.2, 16.5, 45.16]
1  2025-03-28T11:45:19Z  273.15      B  2025-03-28T11:45:19.128742312Z            [300.16, 280.12, 273.15]

Once you have the data ready in this format, you can ingest it into a collection.

# now that we have the data frame in the correct format
# we can ingest it into the Tilebox dataset
collection.ingest(data)

# To verify it now contains the 2 data points
print(collection.info())
Output
Measurements: [2025-03-28T11:44:23.000 UTC, 2025-03-28T11:45:19.000 UTC] (2 data points)

You can now also head on over to the Tilebox Console and view the newly ingested data points there.

​
xarray.Dataset

xarray.Dataset is the default format in which Tilebox Datasets returns data when querying data from a collection. Tilebox also supports it as input for ingestion. The example below shows how to construct an xarray.Dataset from scratch, that matches the schema of the MyCustomDataset dataset and can then be ingested into it. To learn more about xarray.Dataset, visit Tilebox dedicated Xarray documentation page.

import pandas as pd

data = xr.Dataset({
    "time": ("time", [
      "2025-03-28T11:46:13Z",
      "2025-03-28T11:46:54Z",
    ]),
    "value": ("time", [48.1, 290.12]),
    "sensor": ("time", ["A", "B"]),
    "precise_time": ("time", [
      "2025-03-28T11:46:13.345761444Z",
      "2025-03-28T11:46:54.128742312Z",
    ]),
    "sensor_history": (("time", "n_sensor_history"), [
      [13.45, -8.2, 16.5, 45.16, 48.1],
      [280.12, 273.15, 290.12, np.nan, np.nan],
    ]),
})
print(data)
Output
<xarray.Dataset> Size: 504B
Dimensions:         (time: 2, n_sensor_history: 5)
Coordinates:
  * time            (time) <U20 160B '2025-03-28T11:46:13Z' '2025-03-28T11:46...
Dimensions without coordinates: n_sensor_history
Data variables:
    value           (time) float64 16B 48.1 290.1
    sensor          (time) <U1 8B 'A' 'B'
    precise_time    (time) <U30 240B '2025-03-28T11:46:13.345761444Z' '2025-0...
    sensor_history  (time, n_sensor_history) float64 80B 13.45 -8.2 ... nan nan

Array fields manifest in xarray using an extra dimension, in this case n_sensor_history. In case of different array sizes for each data point, remaining values are filled up with a fill value, depending on the dtype of the array. For float64 this is np.nan (not a number). Don’t worry - when ingesting data into a Tilebox dataset, Tilebox will automatically skip those padding fill values and not store them in the dataset.

Now that you have the xarray.Dataset in the correct format, you can ingest it into the Tilebox dataset collection.

collection = dataset.get_or_create_collection("OtherMeasurements")
collection.ingest(data)

# To verify it now contains the 2 data points
print(collection.info())
Output
OtherMeasurements: [2025-03-28T11:46:13.000 UTC, 2025-03-28T11:46:54.000 UTC] (2 data points)

​
Copying or moving data

Since collection.load returns a xarray.Dataset, and ingest takes such a dataset as input you can easily copy or move data from one collection to another.

Copying data like this also works across datasets in case the dataset schemas are compatible.

src_collection = dataset.collection("Measurements")
data_to_copy = src_collection.load(("2025-03-28", "2025-03-29"))

dest_collection = dataset.collection("OtherMeasurements")
dest_collection.ingest(data_to_copy)  # copy the data to the other collection

# To verify it now contains 4 datapoints (2 we ingested already, and 2 we copied just now)
print(dest_collection.info())
Output
OtherMeasurements: [2025-03-28T11:44:23.000 UTC, 2025-03-28T11:46:54.000 UTC] (4 data points)

​
Automatic batching

Tilebox automatically batches the ingestion requests for you, so you don’t have to worry about the maximum request size.

​
Idempotency

Tilebox will auto-generate datapoint IDs based on the data of all its fields - except for the auto-generated ingestion_time, so ingesting the same data twice will result in the same ID being generated. By default, Tilebox will silently skip any data points that are duplicates of existing ones in a collection. This behavior is especially useful when implementing idempotent algorithms. That way, re-executions of certain ingestion tasks due to retries or other reasons will never result in duplicate data points.

You can instead also request an error to be raised if any of the generated datapoint IDs already exist. This can be done by setting the allow_existing parameter to False.

data = pd.DataFrame({
    "time": [
      "2025-03-28T11:45:19Z",
    ],
    "value": [45.16],
    "sensor": ["A"],
    "precise_time": [
      "2025-03-28T11:44:23.345761444Z",
    ],
    "sensor_history": [
      [-12.15, 13.45, -8.2, 16.5, 45.16],
    ],
})

# we already ingested the same data point previously
collection.ingest(data, allow_existing=False)

# we can still ingest it, by setting allow_existing=True
# but the total number of datapoints will still be the same
# as before in that case, since it already exists and therefore
# will be skipped
collection.ingest(data, allow_existing=True)  # no-op
Output
ArgumentError: found existing datapoints with same id, refusing to ingest with "allow_existing=false"

​
Ingestion from common file formats

Through the usage of xarray and pandas you can also easily ingest existing datasets available in file formats, such as CSV, Parquet, Feather and more.

​
CSV

Comma-separated values (CSV) is a common file format for tabular data. It’s widely used in data science. Tilebox supports CSV ingestion using the pandas.read_csv function.

Assuming you have a CSV file named data.csv with the following content. If you want to follow along, you can download the file here.

ingestion_data.csv
time,value,sensor,precise_time,sensor_history,some_unwanted_column
2025-03-28T11:44:23Z,45.16,A,2025-03-28T11:44:23.345761444Z,"[-12.15, 13.45, -8.2, 16.5, 45.16]","Unsupported"
2025-03-28T11:45:19Z,273.15,B,2025-03-28T11:45:19.128742312Z,"[300.16, 280.12, 273.15]","Unsupported"

This data already conforms to the schema of the MyCustomDataset dataset, except for some_unwanted_column which you want to drop before you ingest it. Here is how this could look like:

import pandas as pd

data = pd.read_csv("ingestion_data.csv")
data = data.drop(columns=["some_unwanted_column"])

collection = dataset.get_or_create_collection("CSVMeasurements")
collection.ingest(data)

​
Parquet

Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval. Tilebox supports Parquet ingestion using the pandas.read_parquet function.

The parquet file used in this example is available here.

import pandas as pd

data = pd.read_parquet("ingestion_data.parquet")

# our data already conforms to the schema of the MyCustomDataset
# dataset, so lets ingest it
collection = dataset.get_or_create_collection("ParquetMeasurements")
collection.ingest(data)

​
Feather

Feather is a file format originating from the Apache Arrow project, designed for storing tabular data in a fast and memory-efficient way. It’s supported by many programming languages, including Python. Tilebox supports Feather ingestion using the pandas.read_feather function.

The feather file used in this example is available here.

import pandas as pd

data = pd.read_feather("ingestion_data.feather")

# our data already conforms to the schema of the MyCustomDataset
# dataset, so lets ingest it
collection = dataset.get_or_create_collection("FeatherMeasurements")
collection.ingest(data)
