๐Today, weโre releasing #Memgraph Lab 2.5.0. ๐
Memgraph Lab is a visual UI for exploring and managing data stored in the Memgraph database. Check out the new features below and what they enable you to do.

๐ With the new #Memgraph Lab, you can open more than one query execution view and stack them side by side.
This allows you to run different queries in separate sections and compare their execution speeds and results.

๐ If you have written several queries in the query editor, you can now run a single query by selecting it and pressing the Run Selected button.
You no longer have to comment out all the other queries you don't want to execute.

#SQL vs. #Cypher for hierarchies
Recursive common-table expressions (SQL)
vs.
built-in path variables in #graph

This only shows part of the picture; with recursive CTEs in #SQL I believe it is the case that:
- You can constrain max recursion, but not minimum without writing extra code
Contrast to cypher:
MATCH (e:Employee)-[:REPORTS_TO*3..5]->(:Employee)
- You can constrain max recursion, but not minimum without writing extra code
Contrast to cypher:
MATCH (e:Employee)-[:REPORTS_TO*3..5]->(:Employee)
recursive CTEs are a good example of "implementing a graph abstraction on top of something else". Namely the employee table represents a bunch of node instances; the managerID is a relationship, and the CTE implements a graph traversal.
1/15 Neo4j has always assigned every node (and relationship, but let's focus on nodes) a long value that's called the node's id. Multiply that by the node record size and you know the offset in the node store.
2/15 This id functions as an always present, automatically assigned psedo-property, which allows for O(1) lookups and is also used as the value in our indexes. It's very useful as an addressing mechanism.
3/15 It also has some invariant guarantees, the most interesting of which is that within a transaction, a node id is never reassigned. This, in combination with the above, makes it tempting to use as node identity.

but from the very beginning, thereโs been something about jimin that gives him a sudden strong thrill; a frisson of ecstasy.

I can inspect the triples in the Neo4j browser with
semantics.streamRDF
semantics.streamRDF
I can preview them as a graph with
semantics.previewRDF
semantics.previewRDF
Each class node can be expanded further; in this case revealing kexts and executables that match it.

I really like how the dark version turned out
Halin v0.11 was just released, with significant new stuff! Also a new UI design. Let's jump in (thread)
Cluster members exist in their own slide-out menu. The "tab per member" approach wasn't working with bigger clusters. Now you have room to grow.
It's now possible (with most recent #APOC) to get storage capacity metrics, so you can see how close you are to filling your disk which tends to make @neo4j very unhappy. Thanks to @mesirii and @santand84 for several things that helped make this possible.

We are currently in the keynote. The speaker is talking about how popular Neo4j is
Keynote now telling us about all the new Neo4j features. Examples: location filter, including 3d. Auto cache reheating. I'm interested to know if auto cache reheating is working with query patterns or meant to replace them or what
