Facebook comments: loading taking forever

[jbotero]

Hello everyone.

In PBI Desktop I have been trying, with no luck, to load Facebook comments and likes. I am able to load the data to Query Editor and to transform it in several ways, but when applying the changes, PBI takes forever to load. I have left PBI loading for hours and it keeps "applying query changes".

I have taken the query to show you what I have done:

let
    Source = Facebook.Graph("https://graph.facebook.com/v2.8/hamburguesaselcorral/posts"),
    #"Expanded object_link" = Table.ExpandRecordColumn(Source, "object_link", {"connections"}, {"object_link.connections"}),
    #"Expanded object_link.connections" = Table.ExpandRecordColumn(#"Expanded object_link", "object_link.connections", {"comments"}, {"object_link.connections.comments"}),
    #"Expanded object_link.connections.comments" = Table.ExpandTableColumn(#"Expanded object_link.connections", "object_link.connections.comments", {"message"}, {"object_link.connections.comments.message"}),
    #"Duplicated Column" = Table.DuplicateColumn(#"Expanded object_link.connections.comments", "created_time", "created_time - Copy"),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Duplicated Column", "created_time - Copy", Splitter.SplitTextByDelimiter("T", QuoteStyle.Csv), {"created_time - Copy.1", "created_time - Copy.2"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"created_time - Copy.1", type date}, {"created_time - Copy.2", type time}}),
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each [#"created_time - Copy.1"] > #date(2018, 4, 1))
in
    #"Filtered Rows"

I appreciate all your help and hope that the info I have given to you is enough to solve my problem.

Thanks!

Juan

Hi @jbotero,

Per my understanding about your issue. It might be related to the Expanded object_link. 

Once you load your data from Facebook graph api, the records in object_link are nested. Maybe the number of these records are huge and based on my research it seems like there exists Facebook graph api rate limiting. Please refer:

https://developers.facebook.com/docs/marketing-api/api-rate-limiting

So I would suggest you to try some small number of records. See if the issue persists.

Thanks,
Xi Jin.
