wangjing112 opened a new issue #5710:
URL: https://github.com/apache/shardingsphere/issues/5710
in most time table's sharding rule is same like:
`
defaultTableStrategy:
standard:
shardingColumn: id
shardingAlgorithm:
type: INLINE
props:
algorithm.expression: ${LogicTableName}${id % 2}
`
so if algorithm.expression include LogicTableName ,most of table can use
defaultTableStrategy
just add code in InlineShardingAlgorithm like this:
`
@Override
public String doSharding(final Collection<String> availableTargetNames,
final PreciseShardingValue<Comparable<?>> shardingValue) {
Preconditions.checkNotNull(properties.get(ALGORITHM_EXPRESSION),
"Inline sharding algorithm expression cannot be null.");
String algorithmExpression =
InlineExpressionParser.handlePlaceHolder(properties.get(ALGORITHM_EXPRESSION).toString().trim());
Closure<?> closure = new
InlineExpressionParser(algorithmExpression).evaluateClosure();
Closure<?> result = closure.rehydrate(new Expando(), null, null);
result.setResolveStrategy(Closure.DELEGATE_ONLY);
result.setProperty(shardingValue.getColumnName(),
shardingValue.getValue());
result.setProperty("LogicTableName",
shardingValue.getLogicTableName());
return result.call().toString();
}
`
