Is anybody able to help me work out how to use BatchWriteItem on Arduino using the SDK at awslabs/aws-sdk-arduino
I've got putItem working fine, and from reading the library have worked out I need to change the following (currently shown with putItem as working, Batchwriteitem commented out:
In my header:
PutItemInput putItemInput;
//BatchWriteItemInput batchWriteItemInput;
In the function:
putItemInput.setItem(MinimalMap < AttributeValue > (itemArray, 4));
putItemInput.setTableName(TABLE_NAME);
// batchWriteItemInput.setRequestItems(MinimalMap<MinimalList > requestItems);
//perform putItem and check for errors.
PutItemOutput putItemOutput = ddbClient.putItem(putItemInput, actionError);
//BatchWriteItemOutput batchWriteItemOutput = ddbClient.batchWriteItem(batchWriteItemInput, actionError);
For putItem, the library helps me create the necessary JSON for MinimalMap < AttributeValue > (itemArray, 4) using the following:
MinimalKeyValuePair < MinimalString, AttributeValue > att1(HASH_KEY_NAME, deviceValue);
MinimalKeyValuePair < MinimalString, AttributeValue > att2(RANGE_KEY_NAME, timeValue);
MinimalKeyValuePair < MinimalString, AttributeValue > att3(CATEGORY_KEY_NAME, categoryValue);
MinimalKeyValuePair < MinimalString, AttributeValue > att4(DEBUG_KEY_NAME, debugValue); MinimalKeyValuePair < MinimalString, AttributeValue> itemArray[] = { att1, att2, att3, att4 };
What I can't get my head around is how to use something similar within a loop to create the MinimalMap requestItems needed for batchWriteItem.
I'm learning everything as I go with the power of google, so don't really know what I'm doing - if anyone can point me in the right direction it would be much appreciated - would be great to be able to share a working BatchWriteItem example here for others.
