On the drive back home today I was listening to DevOps Cafe podcast, episode 59<\/a>. \u00a0I’ve recently subscribed to this show and I think this was the first episode of it I ever heard. \u00a0It’s one of many tech talk podcasts, where two or more people chat for a varied period of time on a selection of topics, mostly related to technology.<\/p>\n

In this particular episode, program hosts John and Damon were interviewing the CTO of Basho<\/a> – Dave McCrory<\/a>. \u00a0I wasn’t familiar with either Basho or Dave prior to the episode. \u00a0Gladly, a somewhat lengthy introduction by Dave gave me a good idea who he is. \u00a0What followed though was way more interesting – a discussion about data.<\/p>\n

To be completely honest with you, I haven’t even finished the episode yet (got home right in the middle of it), but I feel like it’s one of those worth blogging about. \u00a0For one, I’ve learned a new term – “data lake”. \u00a0Apparently, that’s a new and fancy way of branding “data warehousing”. \u00a0Here is a bit from TechTarget<\/a>, for example:<\/p>\n

A data lake is a storage repository that holds a vast amount of raw data in its native format until it is needed.<\/p>\n

While a hierarchical data warehouse stores data in files or folders, a data lake uses a flat architecture to store data. Each data element in a lake is assigned a unique identifier and tagged with a set of extended metadata tags. When a business question arises, the data lake can be queried for relevant data, and that smaller set of data can then be analyzed to help answer the question.<\/p>\n

The term data lake is often associated with Hadoop-oriented object storage.<\/p><\/blockquote>\n

But that was just the beginning. \u00a0What followed was a fascinating discussion on Data Gravity<\/a>. \u00a0Obviously, this whole thing is too fresh in my mind and I can’t formulate it well yet, so I suggest you listen to the episode and read the intro on the\u00a0Data Gravity\u00a0site. \u00a0For the sake of brevity:<\/p>\n

[…]\u00a0it\u2019s also a misleading term. Behind it all is the notion that\u00a0data which is near other data is more useful<\/em>, and the tendency of data to cling together comes from the usefulness of the resulting knowledge<\/em>. […]<\/p><\/blockquote>\n

A lot of it seems obvious, but here it’s all put into a nice thought framework, with references to other, more established fields, like math and physics. \u00a0Easily one of the most interesting technology related discussions I’ve heard in a while!<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
