The Fifth Elephant 2014

A conference on big data and analytics

In 2014, infrastructure components such as Hadoop, Berkeley Data Stack and other commercial tools have stabilized and are thriving. The challenges have moved higher up the stack from data collection and storage to data analysis and its presentation to users. The focus for this year’s conference on analytics – the infrastructure that powers analytics and how analytics is done.

Talks will cover various forms of analytics including real-time and opportunity analytics, and technologies and models used for analyzing data.

Proposals will be reviewed using 5 criteria:
Domain diversity – proposals will be selected from different domains – medical, insurance, banking, online transactions, retail. If there is more than one proposal from a domain, the one which meets the editorial criteria will be chosen.
Novelty – what has been done beyond the obvious. Insights – what insights does the proposal share with the audience that they did not know earlier. Practical versus theoretical – we are looking for applied knowledge. If the proposal covers material that can be looked up online, it will not be considered.
Conceptual versus tools-centric – tell us why, not how. Tell the audience what was the philosophy underlying your use of an application, not how an application was used. Presentation skills – proposer’s presentation skills will be reviewed carefully and assistance provided to ensure that the material is communicated in the most precise and effective manner to the audience.



For queries about proposals / submissions, write to


  1. Data Collection and Transport – for e.g, Opendatatoolkit, Scribe, Kafka, RabbitMQ, etc.

  2. Data Storage, Caching and Management – Distributed storage (such as Gluster, HDFS) or hardware-specific (such as SSD or memory) or databases (Postgresql, MySQL, Infobright) or caching/storage (Memcache, Cassandra, Redis, etc).

  3. Data Processing, Querying and Analysis – Oozie, Azkaban, scikit-learn, Mahout, Impala, Hive, Tez, etc.

  4. Real-time analytics

  5. Opportunity analytics

  6. Big data and security

  7. Big data and internet of things

  8. Data Usage and BI (Business Intelligence) in different sectors.

Please note: the technology stacks mentioned above indicate latest technologies that will be of interest to the community. Talks should not be on the technologies per se, but how these have been used and implemented in various sectors, enterprises and contexts.

Getting your hands dirty with Aerospike

Submitted Jul 1, 2014

Aerospike is the new open-source NoSQL database. It is easily the fastest clustered NoSQL database solution. It is also well known for its operational easy-of-use. The objective of the workshop is to get your hands dirty with it.


We will go over the following in the workshop
1. Talk about the architecture of Aerospike
2. Install, setup, configure
3. Use tools built around aerospike
4. Coding using its API (java/node.js)
5. Using Aerospike in existing app frameworks (TBD)
6. Using Aerospike on Amazon cloud.
7. Unleash the high performance of Aerospike

We will organize the people into teams to encourage discussion and mutual help. Also, in the later part of the workshop, the team will use their individual EC2 machines to form a cluster and learn how to deal with cluster.


  • General idea about databases
  • General coding experience

Hardware Requirements:
We will try to provide EC2 machine for everyone to try out. But in the worst case of network failure, its better to have the following as a backup solution.
- A 64-bit machine. (virtual machine is fine)
- Atleast 2G RAM
- Centos 6/RHEL 6/Ubuntu 12.04/Debian 6/Debian 7 OS

Speaker bio

Sunil Sayyaparaju, Engineering Lead at Aerospike, has over 9 years experience working on different types of SQL RDBMS solutions, such as single machine (monolithic), in-memory, distributed shared-disk, and distributed shared-nothing architectures with emphasis in transaction management, storage, access, performance tuning, and recovery areas.

Sunil currently leads Aerospike’s Bangalore office, working on their distributed shared-nothing NoSQL solution. Aerospike is a high-performance, self-balancing, immediately consistent, distributed NoSQL database. Aerospike also has an add on product for replication across data-centers over WAN which supports different complex topologies.

  • we will have multiple presenters
