HI all: BetaRowset has been online for a long time, and has been the default format, performance and stability have been fully verified, currently in our code base still retains support for AlphaRowset, while taking into account the support of AlphaRowset for our follow-up Development has added a lot of unnecessary work, so I propose to remove the alphaRowset support and code in doris.
This work needs to be done in two steps. 1. add the stmt to detect alpharowset tables in version 1.1, before 1.1 upgrade to 1.2 users need to convert all tables in the cluster to betarowset, and we also can add a configuration to control whether to automatically compaction alpha rowset tables to betarowset format 2. remove alpha rowset related code in 1.2 version
