我似乎无法在Dynamo db local中获得流支持,是否支持?我能找到它的唯一迹象是http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Tools.DynamoDBLocal.html#Tools.DynamoDBLocal.Differences
中的最后一个要点使用dynamodb local,似乎忽略了StreamSpecification,因此在调用createTable或describeTable时没有LatestStreamArn
以下代码使用托管的dynamodb服务返回LatestStreamArn,但不返回本地的dynamodb:
ddb.createTable({
TableName: 'streaming_test',
AttributeDefinitions: [
{ AttributeName: 'id', AttributeType: 'S' }
],
KeySchema: [
{ AttributeName: 'id', KeyType: 'HASH' }
],
ProvisionedThroughput: {
ReadCapacityUnits: 5,
WriteCapacityUnits: 5
},
StreamSpecification: {
StreamEnabled: true,
StreamViewType: 'NEW_AND_OLD_IMAGES'
}
}, function (err, data) {
if (err) {
console.log(err, err.stack)
} else {
// data.TableDescription.StreamSpecification and
// data.TableDescription.LatestStreamArn are undefined
// for dynamodb local
console.log(data)
}
})

我无法重现您的问题。我采取的步骤:
java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -inMemory -sharedDb
ddb
替换为dynamodb
。当我这样做时,我得到一个非空且非空的LatestStreamArn arn:aws:dynamodb:ddblocal:000000000000:table/streaming_test/stream/2017-02-12T08:39:03.722
。
dynamodb.createTable({
TableName: 'streaming_test',
AttributeDefinitions: [
{ AttributeName: 'id', AttributeType: 'S' }
],
KeySchema: [
{ AttributeName: 'id', KeyType: 'HASH' }
],
ProvisionedThroughput: {
ReadCapacityUnits: 5,
WriteCapacityUnits: 5
},
StreamSpecification: {
StreamEnabled: true,
StreamViewType: 'NEW_AND_OLD_IMAGES'
}
}, function (err, data) {
if (err) {
console.log(err, err.stack)
} else {
// data.TableDescription.StreamSpecification and
// data.TableDescription.LatestStreamArn are undefined
// for dynamodb local
console.log(data)
}
})
