What are the differences between the transaction isolation levels in databases? This is a suite of test cases which differentiate isolation levels. (by ept)

The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Jepsen: MySQL 8.0.34
Yup! See https://jepsen.io/analyses/mysql-8.0.34#list-append, which also has a link to the code: https://github.com/jepsen-io/mysql/blob/4c239cb5c66a7f1a55fa...
This isn't CONCAT-specific, BTW--we just use CONCAT because it allows us to infer anomalies in linear, rather than exponential time. Same kinds of behaviors manifest with plain old read/write registers.

Memgraph vs. Neo4j: A Performance Comparison
While it is beyond the scope of this blog post to cover the implications of database isolation levels and how weaker isolation levels prevent broad classes of applications from being correctly built on top of them at all, the high-level picture is that Memgraph supports snapshot isolation out of the box, while Neo4j provides a much weaker read-committed isolation level by default. Neo4j does support optional manual locking, but this does not protect all queries by default. In general, it is not practical for most engineers to reason about the subtleties of transaction concurrency control by requiring them to implement their own database locking protocol on top of the application that they are responsible for building and operating.
