  光 HikariCP・A solid, high-performance, JDBC connection pool at last.

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.

  YugabyteDB - the cloud native distributed SQL database for mission-critical applications.

  

The goal is to run it on PostgreSQL compatible databases, especially distributed ones like YugabyteDB. The .jar includes the YugabyteDB JDBC driver, which is a fork of the PostgreSQL one with cluster-aware additions.
