Purpose
When we use flink batch + Paimon in olap. We found that there is a significant difference in query time for different partitions of a table. We attempted to analyze the reasons through logs and querying system tables, but were unsuccessful. Therefore, we added some debug logs.
`/*+ config(cluster=yinxia-test, job_name=20251202) /
SELECT * FROM paimon_ea120.sample.xfc_monitor_cbu_algo_mainse_sa_union_ctr_compare_new_diff
/+ OPTIONS('scan.dedicated-split-generation'='false', 'scan.partitions'='ds=20251202') */ limit 10
/*+ config(cluster=yinxia-test, job_name=20251203) /
SELECT * FROM paimon_ea120.sample.xfc_monitor_cbu_algo_mainse_sa_union_ctr_compare_new_diff
/+ OPTIONS('scan.dedicated-split-generation'='false', 'scan.partitions'='ds=20251203') */ limit 10`
