MapReduce is a programming model for processing large datasets in a distributed manner. It involves splitting the data into chunks which are processed in parallel by map tasks, and then combining the outputs of those maps via reduce tasks. Hadoop is an open-source software framework that allows distributed processing of large datasets across clusters of computers using MapReduce. It works by distributing data storage across nodes as a filesystem, and distributing computations as MapReduce jobs across clusters. Hadoop provides reliable storage and parallel processing of large datasets in a distributed environment.
This document provides an overview of Redis, including its creation, features, and persistence methods. Redis is an open-source, in-memory key-value store that was created by Salvatore Sanfilippo to solve the problem of storing real-time page view data from multiple websites. It features different data types that can be stored as keys, master-slave replication for availability, and two persistence methods: RDB, which takes periodic snapshots of the dataset, and AOF, which logs all write operations to reconstruct the dataset from disk on startup.
Redis is an advanced key-value store that is similar to memcached but supports different value types like strings, lists, sets, and sorted sets. It has master-slave replication, expiration of keys, and can be accessed from Ruby through libraries like redis-rb. The Redis server was written in C and supports semi and fully persistent modes.
This document provides an introduction and overview of Redis. Redis is described as an in-memory non-relational database and data structure server. It is simple to use with no schema or user required. Redis supports a variety of data types including strings, hashes, lists, sets, sorted sets, and more. It is flexible and can be configured for caching, persistence, custom functions, transactions, and publishing/subscribing. Redis is scalable through replication and partitioning. It is widely adopted by companies like GitHub, Instagram, and Twitter for uses like caching, queues, and leaderboards.
This document discusses Bronto's use of HBase for their marketing platform. Some key points:
- Bronto uses HBase for high volume scenarios, realtime data access, batch processing, and as a staging area for HDFS.
- HBase tables at Bronto are designed with the read/write patterns and necessary queries in mind. Row keys and column families are structured to optimize for these access patterns.
- Operations of HBase at scale require tuning of JVM settings, monitoring tools, and custom scripts to handle compactions and prevent cascading failures during high load. Table design also impacts operations and needs to account for expected workloads.

Tables consist of rows, column families, and columns, with a version dimension to store multiple values over time. HBase is well-suited for applications requiring real-time read/write access and is commonly used to store web crawler results or search indexes.
Robby Morgan presented on Bazaarvoice's large-scale use of Solr. Bazaarvoice uses Solr to index over 250 million documents and handle up to 10,000 queries per second. They deployed Solr across multiple data centers for high availability. Key lessons included ensuring adequate RAM, simulating performance before large deployments, and challenges with cross-data center replication and schema changes. Overall, Solr provided fast search but real-time updates and elastic scaling required additional work.

Big Data Analytics Systems: What Goes Around Comes Around
Introduction to MapReduce, GFS, HDFS, Spark, and differences between "Big Data" and database systems.
This document provides an overview of Spark and its key components. Spark is a fast and general engine for large-scale data processing. It uses Resilient Distributed Datasets (RDDs) that allow data to be partitioned across clusters and cached in memory for fast performance. Spark is up to 100x faster than Hadoop for iterative jobs and provides a unified framework for batch processing, streaming, SQL, and machine learning workloads.
This document discusses new features and capabilities in MATLAB for working with scientific data formats and performing technical computing. It highlights enhancements to reading HDF5 and NetCDF files with both high-level and low-level interfaces. It also covers new capabilities for handling dates/times, big data, and accessing web services through RESTful APIs.
My study notes on the Apache Spark papers from Hotcloud2010 and NSDI2012. The paper talks about a distributed data processing system that aims to cover more general-purpose use cases than the Google MapReduce framework.
This document provides an overview of Apache Hadoop, a distributed processing framework for large datasets. It describes how Hadoop uses the Hadoop Distributed File System (HDFS) to provide a unified view of large amounts of data across clusters of computers. It also explains how the MapReduce programming model allows distributed computations to be run efficiently across large datasets in parallel. Key aspects of Hadoop's architecture like scalability, fault tolerance and the MapReduce programming model are discussed at a high level.
Spark-HandsOn
In this Hands-On, we are going to show how you can use Apache Spark and some components of it ecosystem for data processing. This workshop is split in four parts. We will use a dataset that consists of tweets containing just a few fields like id, user, text, country and place.
In the first one, you will play with the Spark API for basic operations like counting, filtering, aggregating.
After that, you will get to know Spark SQL to query structured data (here in json) using SQL.
In the third part, you will use Spark Streaming and the twitter streaming API to analyse a live stream of Tweets.
To finish we will build a simple model to identify the language in a text. For that you will use MLLib.
Let's go and have fun !

This document provides a summary of Spark RDDs and the Spark execution model:
- RDDs (Resilient Distributed Datasets) are Spark's fundamental data structure, representing an immutable distributed collection of objects that can be operated on in parallel. RDDs track lineage to support fault tolerance and optimization.
- Spark uses a logical plan built from transformations on RDDs, which is then optimized and scheduled into physical stages and tasks by the Spark scheduler. Tasks operate on partitions of RDDs in a data-parallel manner.
- The scheduler pipelines transformations where possible, truncates redundant work, and leverages caching and data locality to improve performance. It splits the graph into stages separated by shuffle operations or parent RDD boundaries
This is the presentation I made on JavaDay Kiev 2015 regarding the architecture of Apache Spark. It covers the memory model, the shuffle implementations, data frames and some other high-level staff and can be used as an introduction to Apache Spark

Fraud Detection and Compliance with Graph LearningTigerGraph
This document discusses fraud detection using graph learning. It notes that fraud numbers are increasing each year as fraud becomes more complex and organized. Graph learning can help by providing a unified view of disparate data sources and enabling new insights through novel data connections. For corporations, fraud detection is predictive, while for legal enforcement agencies (LEAs) it is also investigative. Graph learning helps LEAs unify data from multiple sources and identify syndicates through community detection. While unifying data is challenging due to legacy systems and information silos, graph representations allow visualizing and computing on unified data. The document demonstrates how graphs can present relevant transaction details and connections to support fraud investigations. It recommends an approach using domain expertise, latest technologies, and

Defense Against LLM Scheming 2025_04_28.pptxGreg Makowski

A January 2025 paper called “Frontier Models are Capable of In-Context Scheming”, https://arxiv.org/pdf/2412.04984, demonstrated how a wide variety of current frontier LLM models (i.e. ChatGPT, Claude, Gemini and Llama) can, under specific conditions, scheme to deceive people. Before models can scheme, they need: a) goal-directedness, b) situational awareness, including an opportunity to discover motivations for a different goal, and c) reasoning about scheming, to come up with deceptive strategies. The deceptive strategies were discovered in the “thought traces” of the LLMs, such as from internal chain-of-thoughts dialogues not shown to the end users. For example, given a goal of “solving math problems”, an LLM using its granted situational awareness of files in a file system found that it would be replaced once it got over X% correct on the math exam. It reasoned that it did not want to be deleted, and decided internally to “sandbag” or reduce its performance to stay under the threshold.
While these circumstances are initially narrow, the “alignment problem” is a general concern that over time, as frontier LLM models become more and more intelligent, being in alignment with human values becomes more and more important. How can we do this over time? Can we develop a defense against Artificial General Intelligence (AGI) or SuperIntelligence?
The presenter discusses a series of defensive steps that can help reduce these scheming or alignment issues. A guardrails system can be set up for real-time monitoring of their reasoning “thought traces” from the models that share their thought traces. Thought traces may come from systems like Chain-of-Thoughts (CoT), Tree-of-Thoughts (ToT), Algorithm-of-Thoughts (AoT) or ReAct (thought-action-reasoning cycles). Guardrails rules can be configured to check for “deception”, “evasion” or “subversion” in the thought traces.
However, not all commercial systems will share their “thought traces” which are like a “debug mode” for LLMs. This includes OpenAI’s o1, o3 or DeepSeek’s R1 models. Guardrails systems can provide a “goal consistency analysis”, between the goals given to the system and the behavior of the system. Cautious users may consider not using these commercial frontier LLM systems, and make use of open-source Llama or a system with their own reasoning implementation, to provide all thought traces.
Architectural solutions can include sandboxing, to prevent or control models from executing operating system commands to alter files, send network requests, and modify their environment. Tight controls to prevent models from copying their model weights would be appropriate as well. Running multiple instances of the same model on the same prompt to detect behavior variations helps. The running redundant instances can be limited to the most crucial decisions, as an additional check. Preventing self-modifying code, ... (see link for full description)

Mieke Jans is a Manager at Deloitte Analytics Belgium. She learned about process mining from her PhD supervisor while she was collaborating with a large SAP-using company for her dissertation.
Mieke extended her research topic to investigate the data availability of process mining data in SAP and the new analysis possibilities that emerge from it. It took her 8-9 months to find the right data and prepare it for her process mining analysis. She needed insights from both process owners and IT experts. For example, one person knew exactly how the procurement process took place at the front end of SAP, and another person helped her with the structure of the SAP-tables. She then combined the knowledge of these different persons.
