先决条件：在上传数据之前必须完成的步骤 DSBulk
在开始本教程之前，您必须完成以下任务：
-
如果您还没有这样做，请按照中的步骤注册一个 AWS 帐户设置 AWS Identity and Access Management。
-
按照为 Amazon Keyspaces 创建和配置 AWS 证书中的步骤创建凭证。
创建 JKS 信任存储文件。
下载以下数字证书并将文件保存在本地或您的主目录中。
AmazonRootCA1
AmazonRootCA2
AmazonRootCA3
AmazonRootCA4
Starfield Class 2 Root（可选 — 为了向后兼容）
要下载证书，您可以使用以下命令。
curl -O https://www.amazontrust.com/repository/AmazonRootCA1.pem curl -O https://www.amazontrust.com/repository/AmazonRootCA2.pem curl -O https://www.amazontrust.com/repository/AmazonRootCA3.pem curl -O https://www.amazontrust.com/repository/AmazonRootCA4.pem curl -O https://certs.secureserver.net/repository/sf-class2-root.crt注意
Amazon Keyspaces 之前使用锚定在 Starfield Class 2 CA 上的 TLS 证书。 AWS 正在将所有证书全部迁移 AWS 区域 到根据亚马逊信任服务（Amazon Root CAs 1—4）颁发的证书。在此过渡期间，将客户端配置为同时信任 Amazon Root CAs 1—4 和 Starfield 根，以确保所有区域之间的兼容性。
将数字证书转换为 TrustStore 文件并将其添加到密钥库中。
openssl x509 -outform der -in AmazonRootCA1.pem -out temp_file.der keytool -import -alias amazon-root-ca-1 -keystore cassandra_truststore.jks -file temp_file.der openssl x509 -outform der -in AmazonRootCA2.pem -out temp_file.der keytool -import -alias amazon-root-ca-2 -keystore cassandra_truststore.jks -file temp_file.der openssl x509 -outform der -in AmazonRootCA3.pem -out temp_file.der keytool -import -alias amazon-root-ca-3 -keystore cassandra_truststore.jks -file temp_file.der openssl x509 -outform der -in AmazonRootCA4.pem -out temp_file.der keytool -import -alias amazon-root-ca-4 -keystore cassandra_truststore.jks -file temp_file.der openssl x509 -outform der -in sf-class2-root.crt -out temp_file.der keytool -import -alias cassandra -keystore cassandra_truststore.jks -file temp_file.der在最后一步中，您需要为密钥库创建密码并信任每个证书。交互式命令如下所示。

设置 Cassandra 查询语言 Shell (cqlsh) 连接，并按照使用 cqlsh 连接 Amazon Keyspaces 中的步骤确认您可以连接到 Amazon Keyspaces。
-
下载并安装 DSBulk。
要下载 DSBulk，您可以使用以下代码。
curl -OL https://downloads.datastax.com/dsbulk/dsbulk-1.8.0.tar.gz然后解压 tar 文件并将其 DSBulk 添加到您的文件中
PATH，如以下示例所示。tar -zxvf dsbulk-1.8.0.tar.gz # add the DSBulk directory to the path export PATH=$PATH:./dsbulk-1.8.0/bin创建一个
application.conf文件来存储要使用的设置 DSBulk。您可以将以下示例保存为./dsbulk_keyspaces.conf。如果您不在本地节点上，请将localhost替换为本地 Cassandra 集群的联系点，例如 DNS 名称或 IP 地址。记下文件名和路径，因为稍后您需要在dsbulk load命令中指定这些内容。datastax-java-driver { basic.contact-points = [ "localhost"] advanced.auth-provider { class = software.aws.mcs.auth.SigV4AuthProvider aws-region =us-east-1} }要启用 SigV4 支持，请从下载阴影
jar文件GitHub并将其放在 DSBulk lib文件夹中，如下例所示。curl -O -L https://github.com/aws/aws-sigv4-auth-cassandra-java-driver-plugin/releases/download/4.0.6-shaded-v2/aws-sigv4-auth-cassandra-java-driver-plugin-4.0.6-shaded.jar
