A computing system is provided, which is configured to instantiate a testing environment, define an extract, transform, load (ETL) pipeline within the testing environment, generate a test data set to be inputted into the ETL pipeline, generate assert data predicting an output of the ETL pipeline based on the generated test data set, input the test data set into the ETL pipeline to generate output data, compare the assert data to the output data, and validate the output data using the assert data to generate validation data.

Validation of ETL pipeline using assert data

A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.
