Elementary is an open-source data reliability framework for modern data teams. The first module of the framework is data lineage.

Last update: Jan 09, 2023

Overview

Data lineage made simple, reliable, and automated.
Effortlessly track the flow of data, understand dependencies and analyze impact.

Features

Visualization: In browser visual representation of the data lineage graph.
DWH lineage: Effortlessly map data flow in the data warehouse.
Accuracy: Reflects the actual state in the DWH.
Plug-and-play: No need for code changes.

Coming soon:

Monitoring: Present data about freshness, volume and schema on the lineage graph.
Lineage history: Store data about lineage versions and changes.
Column level lineage: Add column-level granularity.
Full lineage: Integrate with downstream and upstream tools to create a full graph.

Quick start

pip install elementary-lineage

# The tool is named edl (Elementary Data Lineage),
# run it to validate the installation:
edl --help

Now we need a connection file in a simple YAML called profiles.yml. Here is a template to create a Snowflake connection profile.
For further instructions go to our quickstart page.

If you use dbt, you can start right away by running this command with the path to your profiles.yml and the relevant profile name:

edl -d ~/profiles_dir -p <profile_name>

If you like what we are building, support us with .

Snowflake Query_id

Is your feature request related to a problem? Please describe. When we get a dbt run failure, I often look through the debug logs to find the exact query which was run.. Also in case of data issues if we want to use snowflake time travel query id make it easier to go back

Describe the solution you'd like dbt run_results.json has snowflake query_id.. add this as part of elementary table dbt_run_results

Describe alternatives you've considered Right now, I look through the snowflake query history to find the sfqid, which works but is a bit tedious.

Additional context Add any other context or screenshots about the feature request here.

How to use days back in report and anomaly detection tests?

We had two questions about this in #support on Slack recently. We need to add it to FAQ and see if there are other parts of the flow where we can better address this.

Support for hourly, weekly, monthly bucket size in anomaly tests

In anomaly detection, the default bucket size is 1 day. I couldn't find a way to configure the size of these buckets.

Checking the code here I think that it's not an easy fix, since it also depends on how the data is collected before this query is executed.

I would keep exploring, but perhaps you can guide me on what should be done to be able to do this.

Parse failed rows as part of the package

Failed dbt test results return an error message that includes the number of failed rows. Today we load the message as is in the package, and parse the number in the CLI using Python. If we move the parsing to the package, users could run their analysis on these data.

Integrate linage visualization with the report UI

Motivation

The report UI is awesome. When we find failures on a table, we would like to investigate affected downstream tables. So, it would be great to support the lineage feature in the report UI.

[Question] How can we prepare `table_monitors_config`?

Overview

I tried to monitor dbt tests with jaffle_shopw by following the documentation. But, I was not able to upload artifacts due to the lack of the destination table. If I am correct, we have to create the table table_monitors_config a head. But, the documentation doesn't describes table_monitors_config. How can we prepare the table?

Send report to a github page report

Is your feature request related to a problem? Please describe.

Sending reports through S3 is great but by default the s3 website will be publicly accessible. They are way to make it private but they seems pretty complex for a single page website.

Describe the solution you'd like

We could host the report on a github page repository, that would ease access control. The idea would be to push the html file to a github repository.

support browser authentication method

Our dbt_runner expect the log messages of dbt run-operation to be in json format. However, browser authentication scenario returns log messages as string. So instead of failing on json parsing, I log the failure and the unsupported log message to our edr file. This is OK because run-operation log message should be in json format as expected, so if anything is returning as string it is currently OK to ignore it. And if something will break in the future, we will have the edr log to understand what happened and what we should change.

Set "elementary_tests" schema to upper case

Hi,

I'm using elementary with Snowflake, where we have set all of our schemas as upper-case. However, in the elementary dbt package the "__tests" is hard-coded as lower-case resulting in a schema named "ELEMENTARY__tests".

Can you give the option of creating a var for this so we have the option of lower-case or upper-case suffix for "__tests".

(Raised this via slack here: https://elementary-community.slack.com/archives/C02CTC89LAX/p1660646926498189)

Thanks!

On-end-run hook failing after updating package version

When running dbt test, I'm getting this error message:

12:36:15  Elementary: Uploaded run results successfully.

[0m12:36:19.363328 [debug] [MainThread]: Postgres adapter: Postgres error: value too long for type character varying(16384)

To Reproduce Steps to reproduce the behavior: Can't currently pin it down exactly. But I upgraded from dbt 1.2.1 and elementary 0.4.11 to dbt 1.3.0 and elementary 0.5.4. So maybe, elementary created the schema using character varying(16384) before and now tries to insert something longer than that (its 16643 characters).

Expected behavior No error.

Environment (please complete the following information):

Add thread_id to dbt run results tables

In the run_results.json file there is a thread id. I Think this would be handy to use to find out the complete execution flow of the DAG: see which models run in parallel and where there might be a hick-up in performance if models have to wait for 1 model to complete
