Store data into new table aa static after api call

Hello everyone, so i have a ppwwr query code that extracts data from api, however as the days go up, the data gets bigger or i start hitting those rate limits, i knoe that i can use databases to store but i dont have servers and im a newbie in this area as im no data engineer. 


My question is if there is a way to store my data after the call to be static in another table. So like after table A got me the api call i needed, i create a new function that will store all my data in Table B and append them as i hit a new call.


Maybe if i create a function or something? If anyone have suggestion olease let me know

Hi @eliasayyy ,

@lbendlin Thanks for your concern about this case!

And @eliasayyy , If I understand you correctly, what you mean by static storage is that only the data is stored, and any data transformation steps that occur in table A do not occur in table B, except for the addition of new data. Is that what you mean?
If I remember correctly, only Duplicate can do this in Power Query.




My suggestion is to Duplicate table A before you do any transformations on table A. Then you add a step in table A(2) using the M function to query what data rows do not exist in the Source step of table A that are not present in the current table A(2) and then append those data rows to the current table A(2).
This way, when you have new data to add to Table A (as long as there are no rows that are identical to the existing data), it should be automatically added to Table A(2), and any data transformations to Table A will not be applied to Table A(2).
However, this is a step-by-step process that needs to be further realized depending on your data.
