升级描述
-
升级节点可执行程序
效果：修复bug，并带来稳定性、性能的提升
操作：停止节点服务，升级节点可执行程序为当前版本，重启节点服务
注意事项：
- 稳定版本：可灰度升级，推荐逐步替换可执行程序进行灰度升级
- 最新版本：需同时升级，需将所有节点停止，替换所有可执行程序后再重启
(请查看这里判断稳定版与最新版)
支持升级的版本：v3.0.0+ -
升级链数据版本
效果：可使用当前版本的最新特性
操作：先完成升级所有节点可执行程序，再参考文档发送交易升级链数据版本至 v3.2.2
注意事项：务必备份原节点的所有账本数据，若操作失误造成升级失败，可通过原数据回滚到升级前的状态
支持升级的版本：v3.0.0+ -
开启实验功能
效果：通过feature开关控制实验功能的开启
操作：升级节点可执行程序后，通过控制台命令
setSystemConfigByKey <feature名> 1开启对应实验功能注意事项：
- feature操作不可逆，打开后不可关闭
- 需确认所有可执行程序版本相同后，再进行feature开启操作
| Feature 名 | 默认状态 | 说明 | |
|---|---|---|---|
| 块内分片 | feature_sharding | 关：0 | 默认关闭，仅在从3.3、3.4升级至当前版本时，feature_sharding打开 |
| 同态加密 | feature_paillier | 关：0 | 默认关闭 |
| rpbft共识 | feature_rpbft | 关：0 | 默认关闭 |
| bug修复 | bugfix_<bug_name> | 开：1 | 从低版本升级默认关闭 |

Upgrade Notice
-
Upgrade node executable
Effect: Fix bugs, and bring stability and performance improvements
Operation: Stop the node service, upgrade the node executable to the current version, and restart the node service
Notice: It is recommended to gradually replace the executable for a phased upgrade
Versions supported before upgration: v3.0.0+
-
Upgrade chain data version
Effect: Can use the latest features of the current version
Operation: First complete the upgrade of all node executables, then refer to the documentation to send a transaction to upgrade the chain data version to v3.2.2
Notice: Be sure to back up all ledger data of the original node. If the operation is incorrect and the upgrade fails, you can roll back to the state before the upgrade using the original data.
Versions supported before upgration: v3.0.0+
-
Enable Experimental Features
Effect: The experimental features can be controlled by the "feature" switch. All experimental features are disabled by default.
Operation: Upgrade the node executable program and connect to the node through the console. Use the command "setSystemConfigByKey feature_name 1" to enable the corresponding experimental feature, except for RPBFT.
Notice:
- Feature operations are irreversible and cannot be closed once opened.
- It is necessary to confirm that all executable program versions are the same before performing the feature enable operation.
| Feature Name | Default Status | Description | |
|---|---|---|---|
| Block Sharding | feature_sharding | Off：0 | Block Sharding is closed by default and only automatically enabled when upgrading from 3.3 or 3.4 to 3.5. |
| Homomorphic Encryption | feature_paillier | Off：0 | Homomorphic Encryption is closed by default. |
| rPBFT Consensus | feature_rpbft | Off：0 | rPBFT Consensus is closed by default. |
| Bug Fix | bugfix_<bug_name> | On：1 | Default closed when upgrading from a lower version. |
