[@gnomesukno]

Overall, very easy to understand explanation video. Good job. Currently I work as a engineering specialist and my role combines data engineering and data analyst. I feel it's best if you can have some understanding from a data engineering perspective it will help you out tremendously when it comes to analyzing said data.

[@SeattleDataGuy]

I agree. From both perspectives. If you're a data engineer who understands the goals of a data analyst or a data analyst who understand the data engineering process, then you can communicate better with the other role.

Looking forward to receiving your support on that!

Although building pipelines is more of a challenge, I am really enjoying azure synapse analytics (serverless sql) for data engineering. Essentially, there is just a data store (with documents) and a data warehouse definition. Data visualization tools just tap the data warehouse definition and an engine serves the relevant transformed data from the (virtual?) warehouse. It feels much cleaner than other approaches I have worked with. I could see this being where things are going: businesses have large object document storage, and Google/Amazon/Microsoft sell mpp engines that enable businesses to easily consume their data as if everything was a small sql database with structured data. Pipelines might still populate the data store, but a lot of the transformation can happen on end-user read.

[@SeattleDataGuy]

I still haven't got to play in the new Microsoft environment. This sounds a little like Looker in terms of how you have defined models and metrics in their ML files. Would you say that is accurate? I think many companies are switching to the EL(T) process where they use a low code solution like Azure data factory or fivetran just to get the data into a datawarehouse and then transform. Do you think this puts data governance at risk. Whenever I hear end-users can set up their own transforms, it gets concerning because then you have 5 definitions of the same field floating around. So many questions.

[@ianfelton5056]

@@SeattleDataGuy Data governance is definitely a concern. The security side can be handled multiple ways, such as native row-level security or dataset truncating by the client (for embedded analytics). As far as multiple definitions of the same field, I think that is more likely to cause havok. It can directly impact the quality of decisioning, along with the confidence to use the information to make decisions. I have not had a chance to try out Looker yet. I am using Power BI, although, from what I have read, I expect Tableau, Power BI and Looker to have a lot of functional overlap. One of the interesting things about Power BI and Synapse is that a person can define Synapse views in a Power BI query. Synapse can be completely empty of any tables, views or anything resulting in data. In this case, an analyst would strictly use Synapse as an engine to query the data store from a data visualization tool. Naturally, Power BI will not let a person connect front-end paramters to these queries :)

[@SeattleDataGuy]

Yup! I agree about havoc being created. I have now worked on several projects with this issue. Not to mention in some cases low-code projects where analysts were just pulling in Billions of rows into Looker or PowerBI and wondering why it is taking so long to pull in the data. But yes, I am loving a lot of these tools. They are making managing all the different data sources so much easier.

[@GuyThompsonFWTX]

I'm in a small shop where I started doing Analyst work (i.e. writing queries, preparing reports for dashboard uploads, troubleshooting alignment between the frontend to the backend) and now I'm learning more about the data engineering aspect of how to manage the pipeline. The biggest problem for me is understanding the legacy code (which is honestly great learning). But I constantly feel like there's a better way, I just don't have the knowledge of how to do it yet. And like other creators have mentioned - there's just so many tools out there now.

[@SeattleDataGuy]

Sounds about right. The legacy code can be great to learn but it can also be difficult to maintain. There honestly is probably a better way, but I assume it would be time consuming to migrate. What is the code base built off of? I have been spending a lot of time moving some companies away from custom code and over to more maintainable solutions like Fivetran and Stitch or if they still want to code Astronomer or Google Cloud Composer.

[@GuyThompsonFWTX]

@@SeattleDataGuy The data and pipeline is managed through GCP using node.js and running cloud scheduler/cloud functions/pubsub/etc. A lot of what I do is gathering data from another Accounting Software and trying to duplicate or create custom reports from the raw data. Part of my problem is that the Accounting Software is also a blackbox in that they don't have much documentation bc they're worried about competitors obtaining source information, so I'm constantly flying blind trying to reverse engineer their tables while also maintaining accounting standards. There's also some hubspot, slack, and nodered stuff in there as well. I feel that there's already some tooling within GCP that could make this easier to manage using Dataflow and DataProc. But we're also talking about moving to Prefect to manage the pipelines as well. I wish there was another me - 1 to manage the day-to-day data analysis work, and another to research the pipeline and options for optimization and improvement.

[@SeattleDataGuy]

I can at least tell you you're not alone! I think Dataflow or Cloud Composer would be good choices. Also with hubspot and slack you could use a low code solution as most low code solutions have data connectors to manage the big business apps. Are they expecting you to build all of this?

[@GuyThompsonFWTX]

@@SeattleDataGuy I won't build all of it. But once a lot of the analysis backlog (mainly updating sql queries) is fixed, or as I become more knowledgeable and able to fix things faster, then I'll transition over to more of the DevOps/DE solutions. I'm already troubleshooting and monitoring the current pipelines which are based off BEAM structure - Source > Staging > DW > Creating Views > import into dashboard, so it's not far-fetched to pick up that task as well, right? This my first Analyst/Engineering role after a decade in Accounting. I feel like I'm doing okay, always could be faster.

[@SeattleDataGuy]

Sounds like a great move! It's pretty typical. How are you enjoying the shift over to the DE/Analyst world?

Quick question, are you a senior data engineer? If so, how long did it take for you to become one from when you started as a junior?

[@SeattleDataGuy]

It took me about 7 years to become a Senior data engineer. But that really depends on the company. I have seen people get the senior title straight from college because they had a masters degree. I would worry less about titles and more on the work. The more you chase something, the farther it gets from you. Zach wilson talks about this on linkedin. He couldn't get a senior DE position at FB, quit, took a year off, went to Netflix and got hired as a Sr. SWE and is now a tech lead at airbnb.

Does a data engineer work often with software engineers and app developers or is that more of a database administrator role?

[@DanielLavedoniodeLima_DLL]

Depends on the company's needs. I've already worked in a company that didn't want to use any third-party paid software outside AWS, so I worked a lot with Python creating connections and managing Airflow and Kafka in EKS and Hadoop in EMR, but now I work at a company that uses a lot of third-party tools and software and my main focus is modeling data using SQL and DBT for Airflow. Data Engineering roles vary a lot from company to company, but what Ben said in this video is mainly the day-to-day routine of all data engineering jobs I've been in.

[@SeattleDataGuy]

I agree with Daniel. It really does depend company to company. For example, at large tech companies you will likely work closely with software engineers because they are building products you are pulling from. Where as in other companies you might be working with external third party solutions so you talk more with solutions engineers and sales engineers. It all depends on how close you are with the data!

[@SeattleDataGuy]

Thank you Daniel for responding! I love it when people share their experiences(besides just me). Like you said, the role of a DE depends company to company. You could work a lifetime and not realize that some DEs do completely different work. So having other perspectives is exactly what this community needs!
