Orsdxy

We have different customer groups like Retail, Not logged, MD and DP. After placing the order we are changing the order number with the Prefix of customer groups. For changing the order number, we have followed below steps.

1) Get the Customer Group

2) Get the Random Order Number

3) Set the Prefix with Random Order Number (example: N-345433)

4) Check the Order Number is exist or Not. If exists again execute Step 3.

5) Set the Order Number to Order Factory

6) Saving the Order

the same we followed the below code with the help of sales_order_place_after observer.

Now we have 40k orders. When ever customer placing order we need to get the order collection and checking with order number weather exist or not?

It's taking too late to get the 40k orders and checking it's taking aroung 20 seconds each order.

If placing order more than one customer at a time it's very difficult to handle. If any of one facing same issue, please suggest to over come.

So is there any chance to over come above situation?

Please suggest us.
