New features in SAP Sybase ASE 15.7 ESD#2

August 23rd, 2012 No comments

Really very Good and useful new features in Sybase ASE 15.7 ESD#2, Checked Out in Rob’s Blog :

 

A few weeks ago (early August 2012), ASE 15.7 ESD2 was released. Despite being an ESD, this ASE release actually contains a truckload of great new features as well. You should really check these out since some of these are just so useful… Let me just highlight a selected few that I like particularly (I hope to come back to some of these topics in the time ahead).

* larger database size – First, the maximum size of an ASE database has been doubled as of 15.7 ESD2. This means that with a 2KB or 16KB page size, the maximum size of a single ASE database is now 8TB or 64TB, respectively (and you can still have thousands of such databases in a single ASE server).
* async database creation
* split/merge partition
* non-blocking table rebuild
* faster update statistics
* faster index creation
* query performance
* Materialized Views
* security & permission

Sybase ASE Database: Cost Considerations and Advantages

June 22nd, 2012 No comments

Recently SAP contracted with IDC to conduct a study of relational database management (RDBMS) users to determine the cost factors encountered by those users in running a relational database, and the extent to which (if any) Sybase ASE could save users money in running their systems. IDC recruited 12 organizations that were willing to let us examine deeply their costs in running both Sybase ASE and other RDBMS products.

IDC asked a number of detailed questions regarding the organizations’ use of database software, their staffing costs, their hardware costs, and their software license and maintenance costs. IDC then analyzed the data using a well-established five-year model for calculating total cost of ownership (TCO), and came to some compelling conclusions.

A SQL GURU trapped in a SAP Sybase IQ World :AntonS

May 23rd, 2012 No comments

It was with a lot of trepidation when I sat down to write this post as I am a MS SQL Server DBA/PROGRAMMER by trade, experience and choice. Having started out on SQL Server 6.5 many many many years ago, I have always been loyal to the database I had come to know and trust. Please do not get me wrong, I do not plan to bash SQL Server as I still use it on a daily basis, this post is merely my take on the comparison of 2 completely different database products….  – AntonS

Petabyte Size Data Store Managed by Hadoop & Map Reduce.

February 11th, 2012 No comments

Hadoop
——–

Source : http://hadoop.apache.org/ & www.
Today, we’re surrounded by data. People upload videos, take pictures on their cell phones, text friends, update their Facebook status, leave comments around the web, click on ads, and so forth. Machines, too, are generating and keeping more and more data. You may even be reading this book as digital data on your computer screen, and certainly your purchase of this book is recorded as data with some retailer.

The exponential growth of data first presented challenges to cutting-edge businesses such as Google, Yahoo, Amazon, and Microsoft. They needed to go through terabytes and petabytes of data to figure out which websites were popular, what books were in demand, and what kinds of ads appealed to people. Existing tools were becoming inadequate to process such large data sets. Google was the first to publicize MapReduce—a system they had used to scale their data processing needs.

This system aroused a lot of interest because many other businesses were facing similar scaling challenges, and it wasn’t feasible for everyone to reinvent their own proprietary tool. Doug Cutting saw an opportunity and led the charge to develop an open source version of this MapReduce system called Hadoop . Soon after, Yahoo and others rallied around to support this effort.

What is Hadoop ?
————–

Hadoop is an open source framework for writing and running distributed applications that process large amounts of data. Distributed computing is a wide and varied field, but the key distinctions of Hadoop are that it is

1.Accessible—Hadoop runs on large clusters of commodity machines or on cloud computing services such as Amazon’s Elastic Compute Cloud (EC2 ).
2.Robust—Because it is intended to run on commodity hardware, Hadoop is architected with the assumption of frequent hardware malfunctions. It can gracefully handle most such failures.
3.Scalable—Hadoop scales linearly to handle larger data by adding more nodes to the cluster.
4.Simple—Hadoop allows users to quickly write efficient parallel code.

Comparing SQL databases and Hadoop:
————————————

Hadoop is a framework for processing data, what makes it better than standard relational databases, the workhorse of data processing in most of today’s applications? One reason is that SQL (structured query language) is by design targeted at structured data. Many of Hadoop’s initial applications deal with unstructured data such as text. From this perspective Hadoop provides a more general paradigm than SQL.
For working only with structured data, the comparison is more nuanced. In principle, SQL and Hadoop can be complementary, as SQL is a query language which can be implemented on top of Hadoop as the execution engine.3 But in practice, SQL databases tend to refer to a whole set of legacy technologies, with several dominant vendors, optimized for a historical set of applications. Many of these existing commercial databases are a mismatch to the requirements that Hadoop targets.

532 nodes cluster (8 * 532 cores, 5.3PB).
Heavy usage of Java MapReduce, Pig, Hive, HBase
Using it for Search optimization and Research.

Facebook

We use Hadoop to store copies of internal log and dimension data sources and use it as a source for reporting/analytics and machine learning.

Currently we have 2 major clusters:

A 1100-machine cluster with 8800 cores and about 12 PB raw storage.
A 300-machine cluster with 2400 cores and about 3 PB raw storage.
Each (commodity) node has 8 cores and 12 TB of storage.
We are heavy users of both streaming as well as the Java APIs. We have built a higher level data warehousing framework using these features called Hive (see the http://hadoop.apache.org/hive/). We have also developed a FUSE implementation over HDFS.

We have multiple grids divided up based upon purpose. * Hardware:
120 Nehalem-based Sun x4275, with 2×4 cores, 24GB RAM, 8x1TB SATA
580 Westmere-based HP SL 170x, with 2×4 cores, 24GB RAM, 6x2TB SATA
1200 Westmere-based SuperMicro X8DTT-H, with 2×6 cores, 24GB RAM, 6x2TB SATA
Software:
CentOS 5.5 -> RHEL 6.1
Sun JDK 1.6.0_14 -> Sun JDK 1.6.0_20 -> Sun JDK 1.6.0_26
Apache Hadoop 0.20.2+patches -> Apache Hadoop 0.20.204+patches
Pig 0.9 heavily customized
Azkaban for scheduling
Hive, Avro, Kafka, and other bits and pieces…

Twitter
——–

We use Hadoop to store and process tweets, log files, and many other types of data generated across Twitter. We use Cloudera’s CDH2 distribution of Hadoop, and store all data as compressed LZO files.

We use both Scala and Java to access Hadoop’s MapReduce APIs
We use Pig heavily for both scheduled and ad-hoc jobs, due to its ability to accomplish a lot with few statements.
We employ committers on Pig, Avro, Hive, and Cassandra, and contribute much of our internal Hadoop work to opensource (see hadoop-lzo)
For more on our use of Hadoop, see the following presentations: Hadoop and Pig at Twitter and Protocol Buffers and Hadoop at Twitter

Yahoo!
