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.

Writing to db
I have used hikari and exposed to do this in the past with postgres, although other dialects are supported.
-
A Tale of Two Connection Pools
I found one suggestion from the author of HikariCP on how to address this, which I implemented and it worked. However, there are additional classes involved, and it feels a little clunky and hard to follow.

Should I use diesel ORM if performance is the most important thing?
Whatever you choose, presuming your app is database heavy, I highly recommend spending time on DB schema design to make all queries as short as possible, avoid relying on transactions, and keep your connection pool tiny. For reference: https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing

Art of README
You reminded me of the HikariCP library and it’s documentation: Clear and simple with references to other libraries trying to accomplish the same thing. It is not in the closure space though.

Java SQL code generator. SQL and OOP united finally.
There's a reason pretty much any system will use a connection pool (Hikari is the de facto standard). Yours should to.

How is the market for Kotlin developers where you live?
HikariCP to pool and conserve relational database connections, which are a scarce and valuable commodity

Recording HikariCP Metrics in Clojure
HikariCP is a popular JDBC connection pool, battle-tested and exhibiting good performance. A Clojure wrapper does the things discussed in this post here. However, our project uses HikariCP directly.

Retry logic for optimistic locking and transparent failover 🐘🚀
YBDemo is a simple Java program that creates an HikariCP connection pool from the hikari.properties file in the current directory, and takes SQL statements to execute as lines from stdin. There's no multi-line statement: each line is a thread, executing the statement in a loop. The goal is to make it easy to run a demo with concurrent threads by providing the set of queries in a simple way, interactive or though file redirection. Only the first column of the first row is displayed, I use row_to_json() or json_agg() to format a larger result into one value. The thread stops if no row is returned, I use RETURNING to get a row from DML.

JDBC Tutorial Part 3: Using Database Connection Pools
Connection pools are configurable, and different implementations have different parameters that you can adjust. For example, you might want to configure the maximum number of connection objects that the pool maintains or the maximum lifetime of a connection in the pool. Refer to the pool implementation documentation for more information.

Configuring Connection Pooling with Spring R2DBC
In Spring Boot application that use blocking connection to DB such as JDBC connection pooling is usually handled by a popular library called HikariCP. Luckily, Spring Data R2DBC already includes connection pooling option that we can use just by enabling it from our properties.
What are some alternatives?
c3p0 - a mature, highly concurrent JDBC Connection pooling library, with support for caching and reuse of PreparedStatements.
spring-boot-r2dbc - An example implementation of Spring Boot R2DBC REST API with PostgreSQL database.
Presto - The official home of the Presto distributed SQL query engine for big data
Vibur DBCP - Vibur DBCP - concurrent and dynamic JDBC connection pool
JDBI - jdbi is designed to provide convenient tabular data access in Java; including templated SQL, parameterized and strongly typed queries, and Streams integration
Flyway - Flyway by Redgate • Database Migrations Made Easy.
jOOQ - jOOQ is the best way to write SQL in Java
H2 - H2 is an embeddable RDBMS written in Java.
FlexyPool - FlexyPool adds metrics and failover strategies to a given Connection Pool, allowing it to resize on demand.
Apache Hive - Apache Hive
sql2o - sql2o is a small library, which makes it easy to convert the result of your sql-statements into objects. No resultset hacking required. Kind of like an orm, but without the sql-generation capabilities. Supports named parameters.
