### Before Creating the Enhancement Request - [X] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary 支持cq文件和Offset从json版本升级到rocksdb版本 Support Upgrade of CQ Files and Offset from JSON Version to RocksDB Version ### Motivation 我们百万队列引入了rocksdb来存储cq和Offset，但是现在没有从json版原地升级到rocksdb版的方案，此方案就是为了解决这个问题 We have introduced RocksDB to store CQ and Offset in our million queues, but currently, there is no solution for in-place upgrading from the JSON version to the RocksDB version. This proposal aims to address this issue. ### Describe the Solution You'd Like 对于Offset，我们会在transferOffsetJsonToRocksdb打开时，broker启动时候做转换。 对于cq，我们提供了俩种格式cq双写的模式，通过rocksdbCQWriteEnable来控制是否同时Dispatch俩种格式的cq，同时我们还提供了检测双写进度的工具，方便寻找合适的时间以切流。 For Offset, we will perform the conversion when the broker starts if transferOffsetJsonToRocksdb is enabled. For CQ, we offer a dual-write mode for two formats, controlled by rocksdbCQWriteEnable to determine whether to dispatch both formats of CQ simultaneously. Additionally, we provide a tool to monitor the dual-write progress, making it easier to find an appropriate time to switch over. ### Describe Alternatives You've Considered nothing ### Additional Context nothing -- This is an automated message from the Apache Git Service.
