Step 1: Create the Source in K

  • Go to Settings, Select Sources and click Add Source

  • Select Hightouch as the Source Type

  • Select "Load from File system" option

  • Give the source a Name - e.g. Hightouch Production

  • Add the Host name for the Hightouch Server

  • Click Finish Setup


Step 2: Getting Access to the Source Landing Directory


Step 3: Install the Collector

It is recommended to use a python environment such as pyenv or pipenv if you are not intending to install this package at the system level.

You can download the Latest Core Library and whl via Platform Settings → SourcesDownload Collectors

Run the following command to install the collector

pip install kada_collectors_extractors_<version>-none-any.whl

You will also need to install the common library kada_collectors_lib for this collector to function properly.

pip install kada_collectors_lib-<version>-none-any.whl

Step 4: Configure the Collector

The collector requires a set of parameters to connect to and extract metadata from Hightouch.

FIELD

FIELD TYPE

DESCRIPTION

EXAMPLE

api_token

string

sdflsl23lksdnfsdfknx

mapping

JSON

Mapping file of data source names against the onboarded host and database name in K

kada_hightouch_extractor_config.json

{
    "api_token": "",
    "output_path": "/tmp/output",
    "mask": true,
    "timeout": 20,
    "mapping": {
        "myDSN": {
            "host": "myhost",
            "database": "mydatabase"
        }
    },
    "compress": true
}

Step 6: Run the Collector

This is the wrapper script: kada_hightouch_extractor.py

import os
import argparse
from kada_collectors.extractors.utils import load_config, get_hwm, publish_hwm, get_generic_logger
from kada_collectors.extractors.hightouch import Extractor

get_generic_logger('root')

_type = 'hightouch'
dirname = os.path.dirname(__file__)
filename = os.path.join(dirname, 'kada_{}_extractor_config.json'.format(_type))

parser = argparse.ArgumentParser(description='KADA Hightouch Extractor.')
parser.add_argument('--config', '-c', dest='config', default=filename)
parser.add_argument('--name', '-n', dest='name', default=_type)
args = parser.parse_args()

start_hwm, end_hwm = get_hwm(args.name)

ext = Extractor(**load_config(args.config))
ext.test_connection()
ext.run(**{"start_hwm": start_hwm, "end_hwm": end_hwm})

publish_hwm(args.name, end_hwm)

If you wish to maintain your own high water mark files elsewhere you can use the above section's script as a guide on how to call the extractor. The configuration file is simply the keyword arguments in JSON format. Refer to this document for more information https://kadaai.atlassian.net/wiki/spaces/KKB/pages/3333849163/Collector+Integration+General+Notes#Storing-HWM-in-another-location

If you are handling external arguments of the runner yourself, you'll need to consider additional items for the run method. Refer to this document for more information https://kadaai.atlassian.net/wiki/spaces/KKB/pages/3333849163/Collector+Integration+General+Notes#The-run-method


Step 7: Check the Collector Outputs

K Extracts

A set of files (eg metadata, databaselog, linkages, events etc) will be generated. These files will appear in the output_path directory you set in the configuration details

High Water Mark File

A high water mark file is created in the same directory as the execution called hightouch_hwm.txt and produce files according to the configuration JSON. This file is only produced if you call the publish_hwm method.

If you want prefer file managed hwm, you can edit the location of the hwm by following these instructions https://kadaai.atlassian.net/wiki/spaces/KKB/pages/3333849163/Collector+Integration+General+Notes#Storing-High-Water-Marks-(HWM)


Step 8: Push the Extracts to K

Once the files have been validated, you can push the files to the K landing directory.

You can use Azure Storage Explorer if you want to initially do this manually. You can push the files using python as well (see Airflow example below)


Example: Using Airflow to orchestrate the Extract and Push to K
