Hi, all
I have found a cache property in JsonSchema, default value was true，calcite
version was 1.20.0
But when I create a calcite connection through DriverManager.getConnection,
cache property value was null after Jackson deserialization.
My code is like this
```
Properties properties = new Properties();
properties.setProperty("schema", schemaName);
result.setProperty("schemaFactory",
MemorySchemaFactory.class.getCanonicalName());
result.setProperty("lex", "MYSQL");
DriverManager.getConnection(CONNECTION_URL, properties);
```
How can I solve this issue?
Regards
