Order Processing Benchmark using In-Memory OLTP

Sample order processing workload that can be used for benchmarking transactional processing with in-memory technologies. The scripts in this folder leverage the In-Memory OLTP feature in SQL Server 2016.

Some results from this benchmark:

About this sample

  • Applies to: SQL Server 2016 (or higher)
  • Key features: In-Memory OLTP
  • Workload: OLTP
  • Programming Language: T-SQL
  • Authors: Jos de Bruijn, Liang Yang

Running this sample

  1. Create the database, tables, and stored procedures using the T-SQL scripts in the corresponding subfolders.
  • The hash indexes are sized for a scale factor of 100, which translates to a 24GB database, with bucket_count double the row count. For larger database and memory size, adjust the bucket counts accordingly.
    • The max bucket_count in SQL Server 2016 is 1 billion. It is OK to have a higher row count. The benchmark performs well with bucket_count of 1 billion and row counts of 5 billion.
  • There are plans to publish scripts for initial populate of the tables. Timeline is TBD.
  • Scripts are also provided for corresponding disk-based tables and traditional stored procedures, to compare performance between disk-based and memory-optimized tables.
  • Data size across the tables is distributed as follows:
Table Weight
Customer 1
Orders 5
OrderLines 25
Products 10
PurchaseCriteria 1
Fulfillment 0
  • The scale factor is a number that governs the actual database size for a given run of the workload. The actual row count for a given table is [scale factor * weight * 10,000]. For example, with scale factor 5, the Products table has 5 * 10 * 10,000 = 500,000 rows.
  1. Run the stored procedures using the following mix.
  • There are plans to make a scalable workload driver available as well. Timeline is TBD.
Stored Procedure Weight
GetOrdersByCustomerID 8
GetProductsByType 6
GetProductsPriceByPK 4
ProductSelectionCriteria 2
InsertOrder 10
FulfillOrders 1

The recommendation is to use two different drivers:

  • a. Main order processing driver(s), each multi-threaded (e.g., 100 or 200 clients), and running the procedures GetOrdersByCustomerID, GetProductsByType, GetProductsPriceByPK, ProductSelectionCriteria, and InsertOrder.
  • b. Fulfillment driver, which runs the procedure FulfillOrders. This driver should have a single client to avoid conflicts.

Workload description

Transaction Type Description
GetOrdersByCustomerID Read-only Select customer info, orders, and order lines for a given customer.
GetProductsByType Read-only Select top 10 products of a given type, ordered by price.
GetProductsPriceByPK Read-only Select all products in a given ID range, ordered by price.
ProductSelectionCriteria Read-only Select top 20 products in a given ID range with the highest computed “closeness” factor against the PurchaseCriteria.
InsertOrder Read-write Insert a new order for a given customer with up to five order lines.
FulfillOrders Read-write Fulfill 10 oldest outstanding orders.
