### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Motivation Users need chain tables with minute-level granularity for scenarios like: - IoT data ingestion with minute-level partitions - Real-time monitoring systems - Incremental processing with fine-grained time windows Example configuration: ``` PARTITIONED BY (`dt` STRING, `hr_min` STRING) TBLPROPERTIES ( 'partition.timestamp-pattern' = '$dt $hr_min:00', 'partition.timestamp-formatter' = 'yyyyMMdd HH:mm:ss', 'chain-table.chain-partition-keys' = 'dt,hr_min' ) ``` or ``` PARTITIONED BY (`dt` STRING, `hr` STRING, `min` STRING) TBLPROPERTIES ( 'partition.timestamp-pattern' = '$dt $hr:$min:00', 'partition.timestamp-formatter' = 'yyyyMMdd HH:mm:ss', 'chain-table.chain-partition-keys' = 'dt,hr_min' ) ``` ### Solution Introduce `ChainPartitionStepExtractor` to dynamically infer the time step from the `partition.timestamp-pattern` and `partition.timestamp-formatter` configuration. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
