   Steps to Reproduce:
   1. Modify server.yml to set the data lake format:`table.datalake.format: 
paimon`
   2. Start Local Cluster by: /usr/local/fluss/bin/local-cluster.sh start 
   ```
   coordinator-server:bind.listeners: FLUSS://{ip}:9123
   tablet-server:bind.listeners: FLUSS://{ip}:9124
   ```
   4. Create Primary Key Table```CREATE TABLE IF NOT EXISTS 
fluss_catalog.fluss.test_prefix_look_up (
       `dt` STRING,
       `user_id` STRING,
       `order_id` STRING,
       `log_time` BIGINT,
       PRIMARY KEY (
           `dt`,
           `user_id`,
           `order_id`
       ) NOT ENFORCED
   ) PARTITIONED BY (dt) WITH (
       'bucket.key' = 'user_id',
       'bucket.num' = '2',
       'table.auto-partition.enabled' = 'true',
       'table.auto-partition.time-unit' = 'DAY',
       'table.auto-partition.num-precreate' = '1',
       'table.auto-partition.num-retention' = '3',
       'table.auto-partition.time-zone' = 'Asia/Shanghai'
   );
   ```
   4. Insert Test Data:
   ```
   INSERT INTO fluss_catalog.fluss.test_prefix_look_up VALUES ('20250728', 
'prefix_look_up_paimon_test', '1234567890123456789', 1);
   ```
   5. Execute prefix look up query:
   ```java
   LookupResult lookup = 
table.newLookup().lookupBy("dt","user_id").createLookuper().lookup(FlussAsyncLookUp.row("20250728","prefix_look_up_paimon_test")).get();
   ```
