@Gulshan Agivetova - There is no NiFi processor that will produce a single NiFi FlowFile that contains a complete listing of all files in a specific target directory, but you can build a flow to do this. The ListSFTP processor will produces one 0 byte FlowFile with the following attributes generated on each: You could pass these 0 byte FlowFiles to a ReplaceText processor that could replace the 0 byte content with new content based off the values assigned to ${path}/${filename} for example. You could then feed all those FlowFiles to a MergeContent processor to merge them in to a single FlowFile with one path/filename per line. Then you can pass that merged file to the ExecuteStream Command processor. - Thanks, Matt ... View more

If you use large attributes, you will have serious issue with the "snapshot" file in the flow content repository. I've just killed my PROD this way last week : the snapshot was too big too fit in memory at startup : my data was lost. ... View more

How to split complexed json arrays into individual json objects with SplitJson processor in NIFI? I don't know how to configure the relationship original, split, failure. Json arrays is below { "scrollId1": "xyz", "data": [ { "id": "app-server-dev-glacier", "uuid": "a0733c21-6044-11e9-9129-9b2681a9a063", "name": "app-server-dev-glacier", "type": "archiveStorage", "provider": "aws", "region": "ap-southeast-1", "account": "164110977718" }, { "id": "abc.company.archive.mboi", "uuid": "95100b11-6044-11e9-977a-f5446bd21d81", "name": "abc.company.archive.mboi", "type": "archiveStorage", "provider": "aws", "region": "us-east-1", "account": "852631421774" } ] } I need to split it into { "id": "app-server-dev-glacier", "uuid": "a0733c21-6044-11e9-9129-9b2681a9a063", "name": "app-server-dev-glacier", "type": "archiveStorage", "provider": "aws", "region": "ap-southeast-1", "account": "164110977718" }, { "id": "abc.company.archive.mboi", "uuid": "95100b11-6044-11e9-977a-f5446bd21d81", "name": "abc.company.archive.mboi", "type": "archiveStorage", "provider": "aws", "region": "us-east-1", "account": "852631421774" } Next, I need to insert another field "time" in front of "id", the first attribute of individual object. I used SplitJson processor, and JSON Path Expression is $.data.id.*, but the relationship reports error. Don't know how to config relationship branches, original, split and failure. Any one have any advice? @Shu ... View more
