BigTable And Hbase
17 likes5,132 views
BigTable is a distributed storage system with three main components: a master server that manages tablet assignment and load balancing, tablet servers that handle reads/writes and split tablets, and a client library. It uses a column-oriented data model indexed by row, column, and timestamp, with tablets located through a hierarchy and assigned by the master to tablet servers. HBase is an open source Apache project that is a BigTable clone written in Java without Chubby or a CMS server, instead using ZooKeeper and the JobTracker.

Parquet Strata/Hadoop World, New York 2013
Parquet Strata/Hadoop World, New York 2013Julien Le Dem Parquet is a columnar storage format for Hadoop data. It was developed collaboratively by Twitter and Cloudera to address the need for efficient analytics on large datasets. Parquet provides more efficient compression and I/O compared to row-based formats by only reading and decompressing the columns needed by a query. It has been adopted by many companies for analytics workloads involving terabytes to petabytes of data. Parquet is language-independent and supports integration with frameworks like Hive, Pig, and Impala. It provides significant performance improvements and storage savings compared to traditional row-based formats.
7. Key-Value Databases: In Depth
7. Key-Value Databases: In DepthFabio Fumarola DynamoDB is a key-value database that achieves high availability and scalability through several techniques:
1. It uses consistent hashing to partition and replicate data across multiple storage nodes, allowing incremental scalability.
2. It employs vector clocks to maintain consistency among replicas during writes, decoupling version size from update rates.
3. For handling temporary failures, it uses sloppy quorum and hinted handoff to provide high availability and durability guarantees when some replicas are unavailable.
NewSQL - The Future of Databases?
NewSQL - The Future of Databases?Elvis Saravia NewSQL databases seek to provide the same scalable performance as NoSQL databases for online transaction processing workloads, while still maintaining the ACID guarantees of a traditional SQL database. NewSQL databases use new architectures like multi-version concurrency control and partition-level locking to allow for horizontal scaling and high availability without sacrificing consistency. They also provide highly optimized SQL engines to query data in a distributed environment.

Dynamo and BigTable in light of the CAP theorem
Dynamo and BigTable in light of the CAP theoremGrisha Weintraub For a long time, relational database management systems have been the only solution for persistent data store. However, with the phenomenal growth of data, this conventional way of storing has become problematic.
To manage the exponentially growing data traffic, largest information technology companies such as Google, Amazon and Yahoo have developed alternative solutions that store data in what have come to be known as NoSQL databases.
Some of the NoSQL features are flexible schema, horizontal scaling and no ACID support. NoSQL databases store and replicate data in distributed systems, often across datacenters, to achieve scalability and reliability.
The CAP theorem states that any networked shared-data system (e.g. NoSQL) can have at most two of three desirable properties:
• consistency(C) - equivalent to having a single up-to-date copy of the data
• availability(A) of that data (for reads and writes)
• tolerance to network partitions(P)
Because of this inherent tradeoff, it is necessary to sacrifice one of these properties. The general belief is that designers cannot sacrifice P and therefore have a difficult choice between C and A.
In this seminar two NoSQL databases are presented: Amazon's Dynamo, which sacrifices consistency thereby achieving very high availability and Google's BigTable, which guarantees strong consistency while provides only best-effort availability.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
