node.js - AWS Lambda: Can I return context and have a task still running? -

right have lambda function in production processes log strings , return them client, so:

1) string received lambda 2) lambda transforms string 3) lambda returns via context.succeed transformed string  

now adding additional step save string in dynamodb table, workflow be:

1) string received lambda 2) lambda transforms string 3) lambda saves string dynamo  4) lambda returns via context.succeed transformed string  

right bit saves function like:

function _saveitem (item) {     dynamo.putitem(item, function (err, data) {         //error handling here         context.succeed(json.stringify(item));     }) } 

i'd know if it's somehow possible fire putitem function and, without waiting end, return item via context.succeed

i assume using "requestresponse" style invoke. true?

if want value returned right away can invoke lambda function (using "event" invoke), , have function write ddb, , return value.

the "event" invoke run asynchronously in background.
