* use the new packed reader and writer api to be compatible with current etcd meta * For the new packed writer API: column groups and paths are explicitly defined by users and won't split column groups by memory in storage v2. Packed writer follows the user-defined column groups to split arrow record and write into the corresponding file path. * For the new packed reader API: read paths are explicitly defined by users. related: #39173 Signed-off-by: shaoting-huang <shaoting.huang@zilliz.com>
