fbin87 opened a new issue, #22196:
URL: https://github.com/apache/shardingsphere/issues/22196
version:5.1.2
splitAndEvaluate method parse every input string, cause metaspace out of
memory error
you can do like this, avoid compiling all input strings
`public List<String> splitAndEvaluate() {
if(Strings.isNullOrEmpty(inlineExpression) ){
return Collections.emptyList();
}
if (!isInlineExpression(inlineExpression)) {
List<String> res = new ArrayList<>();
res.add(inlineExpression);
return res;
}
return flatten(evaluate(split()));
}
`
