Efficient data processing is crucial for businesses and organizations that rely on big data analytics to make informed decisions. One key factor that significantly affects the performance of data processing is the storage format of the data. This article explores the impact of different storage formats, specifically Parquet, Avro, and ORC on query performance and costs in big data environments on Google Cloud Platform (GCP).

By Jose Fernandez , Sebastien Dabdoub , Jason Koch , Artem Tkachuk The Compute and Performance Engineering teams at Netflix regularly investigate performance issues in our multi-tenant environment. The first step is determining whether the problem originates from the application or the underlying infrastructure. One issue that often complicates this process is the "noisy neighbor" problem.

Logging is one of the most important parts of the distributed systems. Many things can break, but when the logging breaks, then we are completely lost. In this blog post, we will understand log levels and how to log efficiently in distributed systems. Logging Levels Whenever we log a message, we need to specify the log level or log severity. It’s an indicator of how important the message is and who should be concerned.

It isn’t the first time I’ve heard this complaint, though I don’t know how widely held that opinion is. But I wonder: is it correct? And why? I think a few things are happening in the AI world. First, developers of AI systems are trying to improve the output of their systems.

When reporting summary statistics for performance test results, there's a common assumption that the data follows a central tendency. But is this always true? What if the data does not exhibit a single central tendency? In such cases, the traditional metrics like averages might be misleading. This article explores why it's crucial to check for modality of performance test results, how to detect multimodal distributions, and how to handle them.

Industrial IoT (IIoT) really means making industrial devices work together so they can communicate better for the sake of ultimately improving data analytics, efficiency, and productivity. But in IIoT, as in other industries, data silos are a huge issue. If your data lives in silos, you’re not making the most of it. Unified Namespace (UNS) plays a key role in making IIoT work well — ie, affordably and efficiently – by eliminating data silos and bringing together under one roof all the data from

When a machine learning model is trained on a dataset, not all data points contribute equally to the model's performance. Some are more valuable and influential than others. Unfortunately value of data for training purposes is often nebulous and difficult to quantify. Applying data valuation to large language models (LLMs) like GPT-3, Claude 3, Llama 3.1 and their vast training datasets has faced significant scalability challenges to date.
