Conditions for inventory lock contention

You can review which conditions create inventory lock contention.

The following three conditions must exist together for high inventory lock contention:

• Sufficiently high number of concurrent transactions that require inventory locks
• Sufficiently long inventory lock-holding times
• Presence of a few common inventory (SKU) in the orders of the concurrently running transactions

If the transaction volume is low and only one transaction is running, this transaction does not experience any inventory lock contention. The likelihood of inventory lock contention grows as the number of concurrently running inventory processing transactions (e.g., createOrder, schedule, release, and so forth) increases.

The impact of lock contention may be minimal if the lock-holding times are very short. Blocked transactions eventually get and lock the inventory item they need to process.

If there are no common SKUs, all the concurrently running transactions are able to process without blocking.
