The fields and partitions information are stored and fetched with different prefixes in the metadata. In the CreateCollectionTask, the RootCoord checks the existing collection information against the metadata. This check fails if the order of the fields or partitions info differs, leading to an error after restarting Milvus. To resolve this, we should use a map in the check logic to ensure consistency. related: https://github.com/milvus-io/milvus/issues/40955 --------- Signed-off-by: shaoting-huang <shaoting.huang@zilliz.com>
