I'm importing a folder of text files. The combined contents are stored in "F" file.
I then reference F two times and apply a different filter to each with F1 and F2.
Now, when refreshing it seems that all three querying the source files, generating long loading times. Also the files are a couple of hundred MBs in size.
My guess would have been that only F reloads the data. F1 and F2 then near-instantaneously being up-to-date as well. But this does not seem to be the case.
Is this expected behaviour?
To improve the performance of referencing table, you need to buffer your table. Like: Table.Buffer(YourTable). After adding the Table.Buffer, when your refresh your reference, it will not access the database again.
