Shard-Query 2.0 Beta 1 released
+4 Vote Up -0Vote Down

It is finally here.  After three years of development, the new version of Shard-Query is finally available for broad testing.

This new version of Shard-Query is vastly improved over previous versions in many ways.  This is in large part due to the fact that the previous version of Shard-Query (version 1.1) entered into production at a large company.  Their feedback during implementation was invaluable in building the new Shard-Query features.   The great thing is that this means that many of the new 2.0 features have already been tested in at least one production environment.

This post is intended to highlight the new features in Shard-Query 2.0.  I will be making posts about individual features as well as posting benchmark results.

MySQL Applier For Hadoop: Real time data export from MySQL to HDFS
Employee +2 Vote Up -0Vote Down

MySQL replication enables data to be replicated from one MySQL database server (the master) to one or more MySQL database servers (the slaves). However, imagine the number of use cases being served if the slave (to which data is replicated) isn't restricted to be a MySQL server; but it can be any other database server or platform with replication events applied in real-time! 
This is what the new Hadoop Applier empowers you to do.
An example of such a slave could be a data warehouse system such as Apache Hive, which uses HDFS as a data store. If you have a Hive metastore associated with HDFS(Hadoop Distributed File System), the Hadoop Applier can populate Hive

Summary of Activities Carried Out during GSoC 2008
+0 Vote Up -0Vote Down

For me, GSOC was a learning experience. I feel that I’ve learned more

from doing this than I have over the course of all my university

classes. So for me, the things that I’ve learned break down as

follows:

Technical things:

  • Installed cygwin and learnt some basic stuff regarding cygwin. Have never really used cygwin before.

  • Learnt how to use bkclient for downloading mysql source code which was replaced by bazaar in the middle of GSOC. Again I have never realy used a distributed version control system.

  • Learnt how to use bazaar which has more functionality than bkclient

  • Downloaded the mysql source code and built it on Windows as well as Linux.

  • Learnt how to debug the mysql source on Windows using Visual Studio

    Week 9 (21st – 28th July)

    Key Accomplishments Last Week

  • Read about the mysql Benchmarking suite and the importance of this suite for mysql.
  • Covered the chapter on Debugging in “Expert Mysql” by Charles A.Bell.
  • The chapter on debugging helped me to get to speed to debug mysql source code on Windows using Visual Studio
  • I also practiced debugging mysql on Linux using ddd and gdb.
  • P.S. I would like to thank Brian, Collin and Leslie for their patience and support. If God wills, I should start some serious hacking very soon.
  • Key Tasks that stalled last Week

    • Installation of perl interface for executing the Benchmarking suite
    • Have some issues with the

    Coding phase 1 week 6
    +0 Vote Up -0Vote Down

    Week 6 (30th June – 7th July 2008 )

    Key Accomplishments Last Week

    1. Implemented a feature to rearranger.c to allow it to accept multiple input files (as requested by Brian). There are a few problems with this feature, however, and I plan on rectifying them soon.

    2. Learnt some basics of Lua.

    3. Learnt a bit about the ddd.

    4. Started learning about the internals of mysql and bought a book, “Expert MySQL” by Charles A. Bell. I already have a fair idea about the working of mysqlslap. Once I get a good grasp of the ddd debugger I should be able to understand mysqlslap more thoroughly.

    Key Tasks that stalled last Week

    None

    Key Concerns

    Introduction of the "PAT" project
    +0 Vote Up -0Vote Down

    This project is one of the Google Summer of Code 2007 projects for MySQL.

    I am a graduate student of University of Toronto, and my mentor of this project is Paul McCullagh.

    The goal of this project to provide a performance analysis tool for a MySQL storage engine PrimeBase XT. We aim to help developers to locate the bottleneck of the system. In contrast to traditional profiling tools, we focus on how to capture the impact of the resource contention through measuring the time spent on waiting critical resources, such as I/O, memory and locks. We also try to provide context information to help developers to identify the critical path.
