Ensuring Reliable Concurrent Writes With Retrying Options

Delta Lake is a resilient storage layer that offers ACID transactions, schema enforcement, and data versioning. However, concurrent writes generate contention since different processes are attempting to write, update, or delete at the same time. This process offers a structured retry mechanism with exponential backoff to handle concurrency in Delta tables.

Delta Table Concurrent Writes Issues

Concurrency failures occur when multiple processes simultaneously attempt to write to the same Delta table. The common failure scenarios are as follows:
