Automatically update entries in an sql database table based on the values of another table

Question

there's this thing where the program has to automatically change an item's column's value in a table based on their Type ID. Basically

-Maintenance Sched Table has Type ID and No. of Days -Items Table has Item ID, Type ID and Status ID

If an Items Table entry's Type ID has a matching Type ID in the MS Table, the Status ID changes (ex. from 1 [active] to 2 [inactive]) every [No. Of Days] days. The big problem i'm facing is that the items table has nearly 10k entries and I have no idea if it'll brick my pc or not if I run it kek. Y'all have any optimization ideas?

        // Retrieve the lists from SharedData
        itemsList = SharedData.getInstance().getItemsList();
        maintStat = SharedData.getInstance().getMaintStat();
        maintSched = SharedData.getInstance().getMaintSched();
    int delay = 0;

        // Loop through itemsList to find matches in maintSched
        for (Item item : itemsList) {

            // Loop through maintSched to check for matching typeID
            for (Item schedItem : maintSched) {
                if (item.getItemTID() == schedItem.getItemTID()) {
                    delay = 10;
            break;
                } else if (item.expiration != null){
            delay = 20
            break;

            }

            if (delay > 0) {
        scheduler.schedule(() -> performMaintenance(item), delay, TimeUnit.DAYS);

        } catch (InterruptedException e) {
            scheduler.shutdownNow();
        }
    }

    private void performMaintenance(Item item) {
        // SQL Update here, for now, just printing
        System.out.println("Performing maintenance on item with ID: " + item.getItemID() + " and typeID: " + item.getItemTID());
    }
