Does another party need to decode the url? What about using a dictionary for the top 10k seen starting combinations and then encode the rest? What about run length encoding? 1-9 for positive sequences. a-i for negative sequences (max means

Querying data in “Cypher” is so much easier. I have 20 years as a database developer, cypher is way better. I can live code 50 complex queries in Cypher before I get one done in SQL.

Yup. Same with Neo4j. You can write your stored procedures in Java ( or any JVM) language. Import any library you want, go crazy.

Neo4j is by far used more than any other graph database out there. Regardless, the standard is not Neo4j specific. It was a collaboration from many companies in the space. They all agree it's a good move.

Gremlin was written by a genius level developer to be used by other genius level developers. There are maybe a handful of Gremlin experts in the entire world and less than 100 that are any good at it. It is extremely powerful, but after a f

Sure. Amazon Neptune is garbage, but that's not the issue. They are competing fair and square here. The problem is when they fork <insert liberally licensed open source project> completely.

If you used Neo4j you would get an easy hierarchy. If you need multiple inheritance then no problem. If all of your classes have completely different properties then no problem. If some discovery reclassified the tree somehow then no proble

You can mix rule based systems and decision trees (well, decision streams) quite nicely in a Graph. Watch the 15 min video on https://maxdemarzi.com/2018/10/08/dynamic-rule-based-decisio... for more details.

Disclaimer: I’m an 8 year Neo4j user and 6 year employee. Neo4j is a great database if you learn how to use it and are willing to get your hands dirty every once in a while (write Java). I keep a blog at maxdemarzi.com on the things you can

Great Library. Available in most of the popular languages. I use it all the time to keep track of node ids instead of using sets of Longs. http://roaringbitmap.org/

Yeah, use a graph database. Most trees end up becoming graphs as changes happen over time and the CTEs won't help much anymore.

I started using Neo4j 8 years ago after a long time as a relational database developer. I needed it for a project building a LinkedIn clone with skills (at the time LinkedIn didn't have skills). I was going to need a massive join table

I hate these types of posts. They do nothing to help the graph database space. How good are they at bidirectional traversals, what about deep traversals in complex networks with more than 50 relationship types? What about x? Every vendor is

You want to trust a vendor that used to restart the db between queries for their benchmarks?

Sure it's hot and humid, thankfully everything is Air Conditioned and I'm in the pool every night. No public transportation means no public transportation that smells like urine. Since housing is so cheap everyone has nice cars.

Move to Round Rock folks! You can get a 4000 sq.ft. home, a half acre yard and a pool for less than a San Francisco studio. You pay $4000 a month to rent a 1 bedroom? You can rent a whole house here for half of that. Pay is the same if you

This is an article written by someone who never heard of Graph Databases. The publish year was 2011, so that makes sense. They were not as well known 6 years ago.
