我使用 AWS NoSQL Workbench 查看我的 DynamoDBLocal 表。
我可以连接到我的 DynamoDBLocal 并列出我拥有的表的名称，但是当我想查看任何表的内容时，我会得到以下堆栈跟踪：

这里是网站的标量和向量循环：
public static void scalarComputation(float[] a, float[] b, float[] c) {
for (int i = 0; i < a.length; i++) {
c[i] = (a[i] * a[i] + b[i] * b[i]) * - 1.0f;
}
}
public static void vectorComputation(float[] a, float[] b, float[] c) {
int i = 0;
for (; i < (a.length & ~(species.length() - 1));
i += species.length()) {
FloatVector<Shapes.S256Bit> va = speciesFloat.fromArray(a, i);
FloatVector<Shapes.S256Bit> vb = speciesFloat.fromArray(b, i); …
