How to optimize this function for large dataset (100k rows & 10 cols) using Google Apps Script?

This function runs ok, but for up to 20k rows. What could I change to make it run fast?

const SOURCE_FILE_ID = 'ID';

function getData() {
  const sourceSheet = SpreadsheetApp.openById(SOURCE_FILE_ID);
  const sourceRng = sourceSheet.getSheetByName('ativcopiar').getRange(1, 1, sourceSheet.getLastRow(), 9);
  const sourceValues  = sourceRng.getValues();

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName('Ativ.');
  var destinationRng = sheet.getRange(1, 1, sheet.getLastRow(), 9);
  destinationRng.clearContent();

  destinationRng.setValues(sourceValues);
}

Sometimes, it exceeds the time limit.

Appreciate any light! Thanks.

Solution

  • I believe your goal is as follows.

    In this case, how about using Sheets API? When Sheets API is used, the process cost can be reduced a little. Ref When Sheets API is used for your script, it becomes as follows.

    Modified script:

    Before you use this script, please enable Sheets API at Advanced Google services.

    function myFunction() {
  const SOURCE_FILE_ID = '###';
  const sheet = SpreadsheetApp.openById(SOURCE_FILE_ID).getSheetByName('ativcopiar');
  const dstSS = SpreadsheetApp.getActiveSpreadsheet();
  var dstSheet = dstSS.getSheetByName('Ativ.');
  var destinationRng = dstSheet.getRange(1, 1, dstSheet.getLastRow(), 9);
  destinationRng.clearContent();
  SpreadsheetApp.flush();
  const values = Sheets.Spreadsheets.Values.get(dstSS.getId(), "'ativcopiar'!A1:I" + sheet.getLastRow()).values;
  Sheets.Spreadsheets.Values.update({values}, dstSS.getId(), "Ativ.", {valueInputOption: "USER_ENTERED"});
}
