- 7. GraalVM = HotSpot VM + α
- 8. GraalVMの+α部分 • Graal – JITコンパイラ • Truffle – 言語実装フレームワーク/ASTインタプリタ • Substrate VM – Java AOTコンパイルコード構築のための ランタイムライブラリとツール
- 9. Top 10 Things To Do With GraalVM 1. High-performance modern Java 2. Low-footprint, fast- startup Java 3. Combine JavaScript, Java, Ruby, and R 4. Run native languages on the JVM 5. Tools that work across all languages 6. Extend a JVM-based application 7. Extend a native application 8. Java code as a native library 9. Polyglot in the database 10.Create your own language

- 21. SQLからJavaScript SQL> select validator.isEmail('alice@example.com’) from dual; VALIDATOR.ISEMAIL('ALICE@EXAMPLE.COM’) -------------------------------------- 1 SQL> select validator.isEmail('bob@example') from dual; VALIDATOR.ISEMAIL('BOB@EXAMPLE’) -------------------------------- 0 https://www.sakatakoichi.com/entry/graalvmembeddeddb
- 25. GraalVM組み込みデータベース • Oracle Database –Oracle Multilingual Engine (Oracle MLE) • MySQL –MySQL MLE Plugin –近日中にMySQL Labsにて公開予定
- 27. dbjsコマンドでのデプロイ $ dbjs deploy -uscott -p tiger -c localhost:1521/ORCLCDB validator +validator.js ... ├─┬isEmail │ └──SCALAR FUNCTION VALIDATOR.ISEMAIL("p0" IN VARCHAR2) RETURN NUMBER ...
- 28. 自作関数も利用可能 $ echo "export function helloworld() : string { return 'HelloWorld'; }" > helloworld.ts $ dbjs deploy -u scott -p tiger -c localhost:1521/ORCLCDB helloworld.ts + helloworld.js └─┬ helloworld └── SCALAR FUNCTION HELLOWORLD.HELLOWORLD RETURN VARCHAR2
