Hi @itscotecgroup_N_A Here are a couple of good resources to better understand Serverless pricing (link1 , link2). In your case since the writes are what drove your invoice, we will dive deeper into that. We calculate WPUs (write processing units) by writes to a document. I.E. for every 1KB written to a document and its corresponding index, we charge the customer 1 WPU. Therefore, WPUs do not depend on the number of write operations but on the number of documents and corresponding indexes that are written to. From link2 (above), we see that 1 Million WPUs are priced between $0.90 and $2.20 depending on the region. Let’s assume the price is $1 per million WPUs. In your case, since each document was less than a kilobyte (94bytes as determined above), each document will cost 1 WPU (assuming each document is under 1KB in size). Therefore, the cost of 196.43 million documents is 196.43 million WPUs. This is in line with the invoice that you see.
Please let me know if you have any further questions.
