## Feature Request **Is your feature request related to a problem? Please describe:** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] --> Now if we want to dump/export data fastly, we need use [backup](http://pegasus.apache.org/administration/cold-backup). However, the backup feature is not friendly for dump data, for example: * Don't support dump immediately, we need create a task and wait excuting * The path contain redundant sub-dir such as `policy name` etc. and don‘t support custom path Above and some other question result in dumping data is complex and especially using [Pegasus-Spark](https://github.com/pegasus-kv/pegasus-spark) to read the dumped data. **Describe the feature you'd like:** <!-- A clear and concise description of what you want to happen. --> I expect the command line should be simple as follow: ```shell # dump/export once # target is hdfs, sub-path is optional, default can be pegasus/cluster_name/table_name >> dump/export table_name hdfs://url sub-path # target is fds, sub-path is optional, default can be pegasus/cluster_name/table_name >> dump/export table_name endpoint bucket sub-path # dump/export periodicly >> dump/export table_name hdfs://url sub-path start_time periodic_time ``` finaly, the data path is: ``` root/pegasus/cluster/table/timestamp/partition/file.sst ``` and then, user can use [Pegasus-Spark](https://github.com/pegasus-kv/pegasus-spark) to read data directly but no need we must offer the `policy name`,`cluster_name`, `table_name`, `fds/hdfs config`. **Describe alternatives you've considered:** <!-- A clear and concise description of any alternative solutions or features you've considered. --> Since the `cold backup` code is complex, so we no need refactor it to achive the above result, but can re-implement new feature **Teachability, Documentation, Adoption, Migration Strategy:** <!-- If you can, explain some scenarios how users might use this, situations it would be helpful in. Any API designs, mockups, or diagrams are also helpful. --> ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
