Storing the values of the data store to each mapNode store would be ugly since i need to download and refresh the data table every hour (~7000 nodes). Question SELECT * FROM

问题 The console gets stuck in a state where every two page refreshes a new closed instance of my indexedDB is displayed. They are all closed except for the one on the top and everything within the application still seems to function normally, however other strange things occur when using the console.
