Sector and Hadoop both provide distributed file systems and parallel data processing capabilities. However, Sector was designed for wide area data sharing and distribution across networks while Hadoop focuses on large data processing within a single data center. Sector also allows direct processing of files and directories using user-defined functions, making it up to 4x faster than Hadoop's MapReduce framework in some benchmarks.

We have entered an era of Big Data. Huge information is for the most part accumulation of information sets so extensive and complex that it is exceptionally hard to handle them utilizing close by database administration devices. The principle challenges with Big databases incorporate creation, curation, stockpiling, sharing, inquiry, examination and perception. So to deal with these databases we require, "exceedingly parallel software's". As a matter of first importance, information is procured from diverse sources, for example, online networking, customary undertaking information or sensor information and so forth. Flume can be utilized to secure information from online networking, for example, twitter. At that point, this information can be composed utilizing conveyed document frameworks, for example, Hadoop File System. These record frameworks are extremely proficient when number of peruses are high when contrasted with composes.

The data management industry has matured over the last three decades, primarily based on relational database management system(RDBMS) technology. Since the amount of data collected, and analyzed in enterprises has increased several folds in volume, variety and velocityof generation and consumption, organisations have started struggling with architectural limitations of traditional RDBMS architecture. As a result a new class of systems had to be designed and implemented, giving rise to the new phenomenon of “Big Data”. In this paper we will trace the origin of new class of system called Hadoop to handle Big data.
This presentation discusses the following topics:
Hadoop Distributed File System (HDFS)
How does HDFS work?
HDFS Architecture
Features of HDFS
Benefits of using HDFS
Examples: Target Marketing
HDFS data replication
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
2. Background Sector is a relatively “new” system that is broadly comparable to Hadoop, and people want to know what are the differences. Is Sector simply another clone of GFS/MapReduce? No. These slides compare most recent versions of Sector and Hadoop as of Nov. 2010. Both software are still under active development. If you find any inaccurate information, please contact Yunhong Gu [yunhong.gu # gmail]. We will try to keep these slides accurate and up to date.
3. Design Goals Sector Hadoop Three-layer functionality: Distributed file system Data collection, sharing, and distribution (over wide area networks) Massive in-storage parallel data processing with simplified interface Two-layer functionality: Distributed file system Massive in-storage parallel data processing with simplified interface
4. History Sector Hadoop Started around 2005 - 2006, as a P2P file sharing and content distribution system for extreme large scientific datasets. Switched to centralized general purpose file system in 2007. Introduced in-storage parallel data processing in 2007. First “modern” version released in 2009. Started as a web crawler & indexer, Nutch, that adopted GFS/MapReduce between 2004 – 2006. Y! took over the project in 2006. Hadoop split from Nutch. First “modern” version released in 2008.
5. Architecture Sector Hadoop Master-slave system Masters store metadata, slaves store data Multiple active masters Clients perform IO directly with slaves Master-slave system Namenode stores metadata, datanodes store data Single namenode (single point of failure) Clients perform IO directly with datanodes
6. Distributed File System Sector HDFS General purpose IO Optimized for large files File based (file not split by Sector but users have to take care of it) Use replication for fault tolerance Write once read many (no random write) Optimized for large files Block based (64MB block as default) Use replication for fault tolerance
7. Replication Sector HDFS System level default in configuration Per-file replica factor can be specified in a configuration file and can be changed at run-time Replicas are stored as far away as possible, but within a distance limit, configurable at per-file level File location can be limited to certain clusters only System level default in configuration Per-file replica factor is supported during file creation For 3 replicas (default), 2 on the same rack, the 3rd on a different rack
8. Security Sector Hadoop A Sector security server is used to maintain user credentials and permission, server ACL, etc. Security server can be extended to connect to other sources, e.g., LDAP Optional file transfer encryption UDP-based hole punching firewall traversing for clients Still in active development, new features in 2010 Kerberos/token based security framework to authenticate users No file transfer encryption
9. Wide Area Data Access Sector HDFS Sector ensures high performance data transfer with UDT, a high speed data transfer protocol As Sector pushes replicas as far away from each other as possible, a remote Sector client may find a nearby replica Thus, Sector can be used as content distribution network for very large datasets HDFS has no special consideration for wide area access. Its performance for remote access would be close to a stock FTP server. Its security mechanism may also be a problem for remote data access.
10. In-Storage Data Processing Sphere HadoopMapReduce Apply arbitrary user-defined functions (UDFs) on data segments UDFs can be Map, Reduce, or others Support native MapReduce as well Support the MapReduce framework
11. Sphere UDF vs. HadoopMapReduce Sphere UDF HadoopMapReduce Parsing: permanent record offset index if necessary Data segments (records, blocks, files, and directories) are processed by UDFs Transparent load balancing and fault tolerance Sphere is about 2 – 4x faster in various benchmarks Parsing: run-time data parsing with default or user-defined parser Data records are processed by Map and Reduce operations Transparent load balancing and fault tolerance
12. Why Sphere is Faster than Hadoop? C++ vs. Java Different internal data flows Sphere UDF model is more flexible than MapReduce UDF dissembles MapReduce and gives developers more control to the process Sphere has better input data locality Better performance for applications that process files and group of files as minimum input unit Sphere has better output data locality Output location can be used to optimize iterative and combinative processing, such as join Different implementations and optimizations UDT vs. TCP (significant in wide area systems)
13. Compatibility with Existing Systems Sector/Sphere Hadoop Sector files can be accessed from outside if necessary Sphere can simply apply an existing application executable on multiple files or even directories in parallel, if the executable accepts a file or a directory as input Data in HDFS can only be accessed via HDFS interfaces In Hadoop, executables that process files may also be wrapped in Map or Reduce operations, but will cause extra data movement if file size is greater than block size Hadoop cannot process multiple files within one operation.
14. Conclusions Sector is a unique system that integrates distributed file system, content sharing network, and parallel data processing framework. Hadoop is mainly focused on large data processing within a single data center. They overlap on the parallel data processing support.
