Sui 归档

Sui 归档是 Sui 上所有交易数据的历史记录，延迟到最新检查点的后面 10 分钟。作为 Sui 节点操作员，你可以将这个历史记录写入对象存储，如 S3、GCS 或类似的存储，以便妥善保存。保存此归档数据被认为是最佳实践，因为 Sui 会删除全节点上的历史交易及其影响。例如，对等节点如果落后当前纪元超过最新几个纪元，可能无法通过同步来追赶所有交易和影响。对等节点可以通过从归档下载此信息而不是依赖同步来进行回退。

Sui 归档节点（将数据写入归档的全节点）不在本地存储中存储历史状态，也不帮助查询历史数据。它们的目的是使对等节点能够追赶到最新检查点，并且对于审计和验证网络上所有交易的完整历史记录非常有用。

创建一个归档节点​

要开始将交易历史记录保存为归档，你需要修改节点配置。打开你的 fullnode.yaml 文件并添加以下配置。默认情况下，fullnode.yaml 文件位于你的 ~/.sui/sui_config 目录中。

state-archive-write-config:
  object-store-config:
    object-store: "S3"
    bucket: "<bucket_name>"
    aws-access-key-id: "<AWS_ACCESS_KEY_ID>"
    aws-secret-access-key: "<AWS_SECRET_ACCESS_KEY>"
    aws-region: "<aws_region>"
    object-store-connection-limit: 20
  concurrency: 5
  use-for-pruning-watermark: false
state-archive-read-config:
  - object-store-config:
      object-store: "S3"
      # Use the same bucket which is being used in `state-archive-write-config`
      bucket: "<bucket_name>"
      aws-access-key-id: "<AWS_ACCESS_KEY_ID>"
      aws-secret-access-key: "<AWS_SECRET_ACCESS_KEY>"
      aws-region: "<aws_region>"
      object-store-connection-limit: 20
    concurrency: 5
    # This should be set to true in this case. Setting this to true
    # would prevent pruning of local transaction data until it is archived
    # in the bucket
    use-for-pruning-watermark: true

设置归档回退​

为了在出现滞后的情况下使你的节点能够回退到档案，将以下内容添加到你的 fullnode.yaml 文件中：

state-archive-read-config:
  - object-store-config:
      object-store: "S3"
      # Use mysten-testnet-archives for testnet 
      # Use mysten-mainnet-archives for mainnet
      bucket: "mysten-<testnet|mainnet>-archives"
      # Use your AWS account access key id
      aws-access-key-id: "<AWS-ACCESS-KEY-ID>"
      # Use your AWS account secret access key
      aws-secret-access-key: "<AWS-SECRET-ACCESS-KEY>"
      aws-region: "<AWS-REGION>"
      object-store-connection-limit: 20
    # How many objects to read ahead when catching up  
    concurrency: 5
    # Whether to prune local state based on latest checkpoint in archive.
    # This should stay false for most use cases
    use-for-pruning-watermark: false
