# What is shardingsphere built with?

shardingsphere is a Java repo built with JetBrains, polyglot, and tomcat-embed-core. It stores its data in Postgres, com.github.ben-manes.caffeine:caffeine, MySQL, etcd, and org.apache.zookeeper:zookeeper, reaches it with jakarta.persistence-api, makes its content with org.apache.commons:commons-csv and org.freemarker:freemarker, validates its data with jakarta.validation-api, is tested with junit-bom, junit-jupiter-engine, mockito-inline, org.junit.jupiter:junit-jupiter-api, org.hamcrest:hamcrest, and 5 more, deploys with commons-logging, io.opentelemetry:opentelemetry-exporter-otlp, jul-to-slf4j, Prometheus, ch.qos.logback:logback-classic, and 3 more, and uses ClickHouse, com.mysql:mysql-connector-j, curator-recipes, H2 Database, jakarta.jms-api, and 7 more.
