A 3-day bug hunt on a 3-person team costs up to β¬7,200 in lost engineering time. This workshop teaches you to prevent that β unit tests, data tests, and integration tests for PySpark and Databricks Lakeflow, including Spark Declarative Pipelines.
Pessimistic replication requires a synchronous communication between the main node writing the data and the replicas. However in some cases the optimistic replication can be more efficient and still guarantee the same final result. One of solutions from this category are conflict-free replicated data types.
Previous post about the Conflict-free Replicated Data Types presented some of basic structures of this type. This one will describe some of recently uncovered types such as: flags, graphs and arrays.
