If I were to do data_array.rolling( time=1000 ).construct('temp_time') - what is going on under hood ? Does it make a 1000 phyiscal copies of the original dataarray - or is it only returning a view ? I feel like it's the latter - but I'm seeing a memory spike (about 20-30% increase in total process memory consumption) when I use it - so there might be something else going on ? Any ideas / pointers would be appreciated. Thanks!
