Husband, father. I do NoSQL for grownups. If you want to learn how to model data as more than a blob I am your guy.

    I built an entire product last month and I'm still in the free tier. The dynamo free tier is pretty nice, and you can use either provisioned or on-demand pricing models --

    The DynamoDB hits just keep on coming! I can’t think of any other database that regularly just gets better while you sleep, no action required.

    When methane burns it converts to CO2 and H2O. Burning all atmospheric methane returns the Earth to pre-industrial greenhouse state. Maybe a billionaire genius with a passion to make the world better might decide to solve this problem?

    5 years ago people said it was crazy. 3 years ago they fought against it. Last year we changed the world!

    This is a courtesy notice that we will sunset support for 3.4 on January 31, 2020. users don't need to upgrade..new features just happen without having to do anything and support never sunsets. Yesteryear's tech stinks, go Cloud Native.

    Said this on another thread, but worth its own tweet. Workaround for case insensitive indexes in : Store partition/sort keys lower case and unaltered strings as attributes. Query keys with lower case conditions, display unaltered strings from item attributes.

    Both stacks will be deployed in a few hours. Cost of impl will be 10% of RDBMS over time.

    How about a vs RDBMS challenge to debunk the idea that relational is cheaper and/or faster to develop with. Take an ERM and a dozen access patterns, build a working data layer prototype. Stand up API and total cost of dev plus 1 year ops. Winner is cheapest.

    If is your goal then don't use a database designed for yesterday's datacenter. Cloud native solutions like offer consumption based pricing that will reduce your cost up to 90% or more.

    I started using NoSQL Workbench for DynamoDB to do my modeling instead of Google Sheets. Once you add some sample data, it is much easier to see how the pivots work with your GSIs. I just started using the "facets" as well, which gives you a way to label and model "entities".

    A solid clue that someone knows nothing about is when they tell you a Document database is better because they use JSON.

    Excited to be presenting at Strata Data & AI Conference in London next April. Come join me for my session on NoSQL Design Patterns and learn why Cloud Native NoSQL is the only choice for your next project.

    Want to save 90% on your NoSQL deployment? Get away from legacy NoSQL and go cloud native. Talk to me to find out how.

    Using the default index on _id like this increases efficiency and reduces write latency by eliminating the need for a secondary index.

    Need Partition and Sort Key patterns in Document stores? Prefix the _id value. For orders by customer sorted by date use "customertId#timestamp" as _id value: db.find("_id":{$gte:"1#2019-12-01", :"1#2020-01-01"}) Returns all orders for customerId "1" in 12/2019.

    Using the default index on _id like this to support complex access patterns eliminates the need for additional indexes, increasing cost efficiency and reducing write latency of the application.

    It was amazing to be in Las Vegas again for AWS re:Invent. It has been an incredible 5+ years and so awesome to see the momentum building behind Single Table Design. Check out my session on Data Modeling in a denormalized…
