Following is the structure of the document i have in a collection in MongoDB
{
"_id": {
"$oid": "5f48e358d43721376c397f53"
},
"heading": "this is heading",
"tags": ["tag1","tag2","tag3"],
"categories": ["projA", "projectA2"],
"content": ["This", "is", "the", "content", "of", "the", "document"],
"timestamp": 1598612312.506219,
"lang": "en"
}
When i am importing data in PDI using the mongodb input step the system is putting each array of the "content" element in a different field I want to select each element in one field (concat the array type elements). for example in the attached image above i want one content field with all the arrays concatenated How do i do that?
