It amazes me how quickly our industry has forgotten the need for DBAs. With these MongoDBs, MPP cloud dbs and Hadoops, everyone seems to have assumed that engineers can now do all db work. This is reflected in the titles too: Data "Engineer".

But from my perspective, this is delusional. There is a lot that goes into DBA's experience that is not solved by the performance improvements in databases over the past decade. But there are more choices. 20-30 years ago, you would have been forced to write code on Oracle and you would have asked for help before deciding how to structure the data. Today, with more choices, you just read some online opinions, and jump on it without any internal resource to guide you.

Not saying the world of Oracle was great, but the young on this thread (me included) would benefit from respecting the experience of the old.

Who would have though given that at some point this "Don't use MongoDB" seemed to have taken over HN: https://news.ycombinator.com/item?id=3202081

Filter by Product: Data Studio, and the result says it all: https://www.google.com/analytics/success-stories/#?modal_act...

"Sorry, we couldn't find any success stories to match those filters."

A BigQuery partner here and a long-time user of Redshift. (https://cloud.google.com/partners/directory/#?q=caura https://discourse.looker.com/t/bigquery-migrating-from-legac... and you can Google my creds for Redshift with "Troubleshooting Redshift performance")

So having benchmarks tests is great as a general guideline for what works under different architectures/schema designs. Unfortunately, benchmarking is highly subjective to the initial choices. I am a big fan of BigQuery (enough to go through Google's vetting process), but there are plenty of performance issues that I've run into it that would have been easily resolved with Redshift. Here are some concrete examples:

1) Running a Query across several very small tables. It turns out that occasionally querying small tables causes heavy network traffic within Google's distributed system. The solution on Redshift would be to adjust distribution. On Google, however, you don't have any control over this. You just have to hope that Google's algorithms pick up the issue based on usage (they don't).

2) Joining large tables. Avoid joining large tables in BigQuery. In Redshift the join would have been done by making sure that the sortkey is set on the column that is used for a join on the (typically) right table. Then having a common distkey between the two tables (this way the relevant data on both tables lives on the same node. BigQuery just throws resources at the problem. Well, it turns out that throwing resources at the problem is super slow (think 5-15 Redshift seconds vs. 200 BQ seconds).

Re: Snowflake. Can't speak to it as I haven't had personal experience. I have worked with Data people who had opinions on both favorable and negative sides of the spectrum. This just suggests to me that just like Redshift and BigQuery, Snowflake is not a universal solution. You really need to understand: 1) what your goals are for the usage among varying consumers 2) what skill set do the various users of the database have

@falumi Where to send them?

Hey Max,

Like the product. This is going to be big!

Not interested in a job, but would love to get to know your team better. I think there might be some alignment. Anyways, you can check out what I do here: https://www.caura.co

So I hate to disappoint everyone. Such contract really cannot be viewed the way this was summarized through an email. One paragraph has to be interpreted in the context of everything else.

Moreover, everyone uses this language. It is funny, but I suspect that most of Silicon Valley just recycles the same 3-4 contracts, that individual lawyers just modify slightly.

I have now worked with 60+ tech companies (Looker, Gigster, Strava, etc) - with 15 of them I had to look over the verbiage on my own.

With a first couple, I was just as suspicious. But after discussing with lawyers, I learned that there are two major issues:

1) not everything put in the contract is enforceable. In fact, just because all lawyers recycle the same contract, does not make it more enforceable. It is a simple leverage in bullying that lawyers depend on, should something occur

2) individual paragraphs have to be interpreted in the context of the entire engagement. In other words, did you have have access to Client's data on other projects. Yes, then you bet, your IP rights should be waived as they pertain to those projects.

Bottom line, relax and focus on good faith.

@somid3 I would like to invite you to our analytics community: http://www.innerjoins.org

and to @vivekd's request for data on this topic: https://my.caura.co/investigating-fraudulent-clicks-in-googl...

- plenty of data here. Happy to provide a SQL interface for it if you can prove that you've got the chops

When all else fails, try renaming the business...

Caura Consulting | Data Analyst | Remote Only | Part-Time

Caura Consulting, a sponsoring organization of http://www.innerjoins.org, is looking for a very experienced Analyst to help grow the non-profit community, InnerJoin. Your job is to facilitate conversations, help answer some analytical questions, and prompt new topics for discussions.

Daily availability is required. Hours are flexible.

If you do data engineering, you can work with me: https://www.caura.co - my clients are all remote

Facebook, Google - people treat their numbers as holy because they have so many smart people working for them (and because they have very good PR departments).

But I beg to differ. I think it is about time we have a community investigating these metrics: https://segahm.github.io/adwords_investigators.html

my wife's response: http://ahedgehoginthefog.weebly.com/hedgehogs-adventures/-fe...

Could not agree more. That's why my wife's preschool is play-based: http://www.petitefrance.xyz

Sure, there is academic stuff and learning. And as a licensed preschool, we have full-time supervision. But the helicopter parent as a concept is absent in French upbringing. Instead, my wife focuses on building kids inner-confidence through play and social interactions.

For me everything boils down to: as an engineer, how well aware are you of your domain. If you are, then you know how to integrate tools and code together to produce the next invention. I've written a post for engineers on precisely that topic just last week: https://my.caura.co/why-build-software-in-house-not-f3c9bc72...

Hi, I am the author. Yes, agree on the title. Thanks for keeping me honest. Changed it to "Investigating..."

right. all has been resolved after we submitted screenshots.
