[GitHub] [shardingsphere] strongduanmu opened a new issue, #12648: Consider supporting case sensitivity of table and column names in ShardingSphere metadata
strongduanmu opened a new issue, #12648:
URL: https://github.com/apache/shardingsphere/issues/12648
## Feature Request
By default, ShardingSphere metadata is not case sensitive when processing table names and column names. This may cause some problems on case-sensitive databases.
```java
/**
* ShardingSphere schema.
*/
@Getter
public final class ShardingSphereSchema {
private final Map<String, TableMetaData> tables;
@SuppressWarnings("CollectionWithoutInitialCapacity")
public ShardingSphereSchema() {
tables = new ConcurrentHashMap<>();
}
public ShardingSphereSchema(final Map<String, TableMetaData> tables) {
this.tables = new ConcurrentHashMap<>(tables.size(), 1);
tables.forEach((key, value) -> this.tables.put(key.toLowerCase(), value));
}
...
}
/**
* Federation schema meta data.
*/
@Getter
public final class FederationSchemaMetaData {
private final String name;
private final Map<String, FederationTableMetaData> tables = new LinkedHashMap<>();
public FederationSchemaMetaData(final String name, final Map<String, TableMetaData> metaData) {
this.name = name;
for (Entry<String, TableMetaData> entry : metaData.entrySet()) {
tables.put(entry.getKey(), new FederationTableMetaData(entry.getValue().getName(), entry.getValue()));
}
}
/**
* Renew.
*
* @param metaData meta data
*/
@Synchronized
public void renew(final TableMetaData metaData) {
tables.put(metaData.getName().toLowerCase(), new FederationTableMetaData(metaData.getName(), metaData));
}
...
}
```
Therefore, it is hoped that ShardingSphere can dynamically handle case sensitivity according to the database configuration.
