Cassandra is one of the most popular datastores in big data and ML applications. Data analysis at scale with fast query response is critical for business needs, and while Cassandra with Spark integration allows running an analytical workload, it can be slow. Shradha Ambekar dives into the challenges faced at Intuit and the solutions her team implemented to improve performance by 100x. Read more.

Graphs provide a method to store and analyze the relationships within the data. Algorithms deepen our understanding of data through aggregation and perspectives to help developers make valuable business decisions for the future based on existing scenarios. Amy Hodler and Mark Needham lead you through a crash course in how to use graph algorithms as part of your big data toolkit. Read more.

Managing large stateful applications is tough. Matt Schallert outlines the challenges of automating stateful systems at scale and details how embracing a declarative approach can ease operation and automation of these systems on orchestrators such as Kubernetes. He then demonstrates how to apply this methodology to different types of stateful workloads. Read more.

Data-intensive applications, with many layers of transformations and movement from different data sources, can often be challenging to maintain and iterate even after they are initially built and validated. Jiaqi Liu explores how to factor in monitoring, alerting, and tracing data lineage when building data applications that move and transform data across multiple dependencies. Read more.
