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

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.

I believe your goal is as follows.

You want to reduce the process cost of your script.

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"});
}

Modified script:
