 - data_region_group_per_database
     - for 3C3D cluster mode: Cluster CPU total core num / data_replication_factor
     - for 1C1D standalone mode: use virtual_storage_group_num in v0.13
+- When encountering messages like "There are too many timeseries in memory", please modify the following configuration
+  - storage_query_schema_consensus_free_memory_proportion: double the memory proportion of schema
 
 Data migration:
 After modified the configuration, use load-tsfile tool to load the TsFiles of v0.13 to v1.0.

     - 如果是 3C3D 高性能分布式：则改为：集群 CPU 总核数/ 数据副本数
     - 如果是 1C1D，则改为：等于 0.13 的 virtual_storage_group_num 即可 （"database"一词 与 0.13 中的 "sg" 同义）
+- 如果启动时遇到元数据内存不足的提示，这是因为1.0版本中分配给元数据的内存不再全部用于 schema region 存储
+  - storage_query_schema_consensus_free_memory_proportion：增大 schema 的内存比例至两倍
 
 数据迁移：
 配置修改完成后，通过 load-tsfile 工具将 0.13 的 TsFile 都加载进 1.0 的 IoTDB 中，即可使用。
