Loading Zendesk Data to ClickHouse with Python Library `dlt`

Need help deploying these pipelines, or figuring out how to run them in your data stack?

Join our Slack community or book a call with our support engineer Violetta.

This guide provides instructions on how to use the open-source Python library, dlt, to load data from Zendesk, a widely trusted customer service software, into ClickHouse, a high-speed, column-oriented database system. Zendesk serves over 200K customers, offering various communication channels like text, mobile, phone, email, live chat, and social media. ClickHouse uses SQL queries to generate real-time analytical data reports. The dlt library facilitates this data transfer, enabling users to capitalize on ClickHouse's reporting capabilities using Zendesk data. For more information on Zendesk, visit https://www.zendesk.de.

`dlt` Key Features

Pipeline Metadata: dlt pipelines leverage metadata to provide governance capabilities. This metadata includes load IDs, which consist of a timestamp and pipeline name. Load IDs enable incremental transformations and data vaulting by tracking data loads and facilitating data lineage and traceability. Read more about lineage.
Schema Enforcement and Curation: dlt empowers users to enforce and curate schemas, ensuring data consistency and quality. Schemas define the structure of normalized data and guide the processing and loading of data. Read more: Adjust a schema docs.
Schema evolution: dlt enables proactive governance by alerting users to schema changes. When modifications occur in the source data’s schema, dlt notifies stakeholders, allowing them to take necessary actions. Read more about Schema evolution.
Scaling and finetuning: dlt offers several mechanism and configuration options to scale up and finetune pipelines. Running extraction, normalization and load in parallel. Writing sources and resources that are run in parallel via thread pools and async execution. Read more about performance.
Incremental loading: dlt provides the capability for incremental loading in consecutive runs with dlt. The state of your incremental loads will be persisted in your selected destination and restored and used on each new load. Read more about Incremental loading.

Getting started with your pipeline locally

0. Prerequisites

dlt requires Python 3.8 or higher. Additionally, you need to have the pip package manager installed, and we recommend using a virtual environment to manage your dependencies. You can learn more about preparing your computer for dlt in our installation reference.

1. Install dlt

First you need to install the dlt library with the correct extras for ClickHouse:

pip install "dlt[clickhouse]"

The dlt cli has a useful command to get you started with any combination of source and destination. For this example, we want to load data from Zendesk to ClickHouse. You can run the following commands to create a starting point for loading data from Zendesk to ClickHouse:

# create a new directory
mkdir zendesk_pipeline
cd zendesk_pipeline
# initialize a new pipeline with your source and destination
dlt init zendesk clickhouse
# install the required dependencies
pip install -r requirements.txt

The last command will install the required dependencies for your pipeline. The dependencies are listed in the requirements.txt:

dlt[clickhouse]>=0.3.8

You now have the following folder structure in your project:

zendesk_pipeline/
├── .dlt/
│   ├── config.toml          # configs for your pipeline
│   └── secrets.toml         # secrets for your pipeline
├── zendesk/                   # folder with source specific files
│   └── ...
├── zendesk_pipeline.py        # your main pipeline script
├── requirements.txt         # dependencies for your pipeline
└── .gitignore               # ignore files for git (not required)

2. Configuring your source and destination credentials

The dlt cli will have created a .dlt directory in your project folder. This directory contains a config.toml file and a secrets.toml file that you can use to configure your pipeline. The automatically created version of these files look like this:

generated config.toml

# put your configuration values here

[runtime]
log_level="WARNING"  # the system log level of dlt
# use the dlthub_telemetry setting to enable/disable anonymous usage data reporting, see https://dlthub.com/docs/telemetry
dlthub_telemetry = true

generated secrets.toml

# put your secret values and credentials here. do not share this file and do not push it to github

[sources.zendesk.credentials]
subdomain = "subdomain" # please set me up!
email = "email" # please set me up!
password = "password" # please set me up!

[destination.clickhouse]
dataset_name = "dataset_name" # please set me up!

[destination.clickhouse.credentials]
database = "default"
password = "password" # please set me up!
username = "default"
host = "host" # please set me up!
port = 9440
http_port = 8443

2.1. Adjust the generated code to your usecase

Further help setting up your source and destinations

Read more about setting up the Zendesk source in our docs.
Read more about setting up the ClickHouse destination in our docs.

3. Running your pipeline for the first time

The dlt cli has also created a main pipeline script for you at zendesk_pipeline.py, as well as a folder zendesk that contains additional python files for your source. These files are your local copies which you can modify to fit your needs. In some cases you may find that you only need to do small changes to your pipelines or add some configurations, in other cases these files can serve as a working starting point for your code, but will need to be adjusted to do what you need them to do.

The main pipeline script will look something like this:

import time
from typing import Any

import dlt
from dlt.common.time import timedelta
from zendesk import (
    pendulum,
    zendesk_chat,
    zendesk_talk,
    zendesk_support,
    make_date_ranges,
)


def incremental_load_all_default() -> Any:
    """

    """
    # FULL PIPELINE RUN
    pipeline = dlt.pipeline(
        pipeline_name="dlt_zendesk_pipeline",
        destination='clickhouse',
        full_refresh=False,
        dataset_name="sample_zendesk_data3",
    )

    # zendesk support source function
    data_support = zendesk_support(load_all=True)
    # zendesk chat source function
    data_chat = zendesk_chat()
    # zendesk talk source function
    data_talk = zendesk_talk()
    # run pipeline with all 3 sources
    info = pipeline.run(data=[data_support, data_chat, data_talk])
    return info


def load_support_with_pivoting() -> Any:
    """
    Loads Zendesk Support data with pivoting. Simply done by setting the pivot_ticket_fields to true - default option. Loads only the base tables.
    """
    pipeline = dlt.pipeline(
        pipeline_name="zendesk_support_pivoting",
        destination='clickhouse',
        full_refresh=False,
    )
    data = zendesk_support(load_all=False, pivot_ticket_fields=True)
    info = pipeline.run(data=data)
    return info


def incremental_load_all_start_date() -> Any:
    """

    1st Jan 2000 if there has been no previous loading of the resource. With this setting, the sources will load data since the given data for all incremental endpoints.
    Last load time will still be updated.
    """

    # Choosing starting point for incremental load - optional, the default is the last load time. If no last load time
    # the start time will be the 1st day of the millennium
    # start time needs to be a pendulum datetime object
    start_date = pendulum.DateTime(year=2023, month=1, day=1).in_timezone("UTC")

    pipeline = dlt.pipeline(
        pipeline_name="dlt_zendesk_pipeline",
        destination='clickhouse',
        full_refresh=False,
        dataset_name="sample_zendesk_data",
    )
    data = zendesk_support(load_all=True, start_date=start_date)
    data_chat = zendesk_chat(start_date=start_date)
    data_talk = zendesk_talk(start_date=start_date)
    info = pipeline.run(data=[data, data_chat, data_talk])
    return info


def incremental_load_with_backloading() -> Any:
    """Backload historic data in ranges. In this method we load all tickets so far created since Jan 1st 2023 but one week at a time
    and then switch to incrementally loading new tickets.
    This can useful to reduce the potiential failure window when loading large amounts of historic data.
    This approach can be used with all incremental Zendesk sources.
    """
    pipeline = dlt.pipeline(
        pipeline_name="dlt_zendesk_pipeline",
        destination='clickhouse',
        full_refresh=False,
        dataset_name="sample_zendesk_data",
    )

    # Load ranges of dates to load between January 1st 2023 and today
    min_start_date = pendulum.DateTime(year=2023, month=1, day=1).in_timezone("UTC")
    max_end_date = pendulum.today()
    # Generate tuples of date ranges, each with 1 week in between.
    ranges = make_date_ranges(min_start_date, max_end_date, timedelta(weeks=1))

    # Run the pipeline in a loop for each 1 week range
    for start, end in ranges:
        print(f"Loading tickets between {start} and {end}")
        data = zendesk_support(start_date=start, end_date=end).with_resources("tickets")
        info = pipeline.run(data=data)
        print(info)

    # Backloading is done, now we continue loading with incremental state, starting where the backloading left off
    print(f"Loading with incremental state, starting at {end}")
    data = zendesk_support(start_date=end).with_resources("tickets")
    info = pipeline.run(data)
    print(info)


if __name__ == "__main__":
    # simple run where everything is loaded
    start = time.time()
    load_info = incremental_load_all_default()
    end = time.time()
    print(load_info)
    print(f"Time taken: {end-start}")

Provided you have set up your credentials, you can run your pipeline like a regular python script with the following command:

python zendesk_pipeline.py

4. Inspecting your load result

You can now inspect the state of your pipeline with the dlt cli:

dlt pipeline dlt_zendesk_pipeline info

You can also use streamlit to inspect the contents of your ClickHouse destination for this:

# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline dlt_zendesk_pipeline show

5. Next steps to get your pipeline running in production
