TCP Trace

I found a useful tool named sniffer to help us analyze network packages (this tool can capture packages on specific port)

I use sniffer to analyze mysql and redis packages (translate these packages to normal queries)

#./vc-redis-sniffer –help

vc-redis-sniffer is a utility from VividCortex to monitor query activity and write results to a file.
See --license for the terms governing your usage of this program.

  -binding="[::]:6379"         This is a list of comma separated bind strings as seen in /proc/net/tcp
  -help="false"                Show this usage message
  -license="false"             Print the usage terms of this program
  -output=""                   Filepath to output queries to. Defaults to stdout if none specified.
  -show-database="false"       Include a 'USE `database`' for every statement. Supersedes show-database-changes.

Dynomite-manager: Managing Dynomite Clusters

Dynomite has been adopted widely inside Netflix due to its high performance and low latency attributes. In our recent blog, we showcased the performance of Dynomite with Redis as the underlying data storage engine. At this point (Q2 2016), there are almost 50 clusters with more than 1000 nodes, centrally managed by the Cloud Database Engineering (CDE) team. CDE team has a wide experience with other data stores, such as Cassandra, ElasticSearch and Amazon RDS.Dynomite is used at Netflix both as a:

Sometimes a Variety of Databases is THE Database You Need

We were just leafing through the 2015 edition of The DZone Guide to Database and Persistence Management, and we noticed some interesting stats in the guide's included survey, about which we'd like to share some observations. The survey is one of the ebook's central features, and it includes feedback from over 800 IT Professionals, with 63% of those respondents coming from companies with over 100 employees and 69% with over 10 years of experience -- they represent a significant and important cross-section of our industry.

These kinds of reports can be enlightening, as they offer the opportunity to take some of our principles and pin them to the hard facts and numbers of actual database activity, in the field. 

In a section titled "One Type of Database is Usually Not Enough," the report reveals that it's stadard …

What technologies are you running alongside MySQL?

In many environments MySQL is not the only technology used to store in-process data.

Quite frequently, especially with large-scale or complicated applications, we use MySQL alongside other technologies for certain tasks of reporting, caching as well as main data-store for portions of application.

What technologies for data storage and processing do you use alongside MySQL in your environment? Please feel free to elaborate in the comments about your use case and experiences!

Note: There is a poll embedded within this post, please visit the site to participate in this post's poll.

Our 2013 Database survey is now live

451 Research’s 2013 Database survey is now live at investigating the current use of database technologies, including MySQL, NoSQL and NewSQL, as well as traditional relation and non-relational databases.

The aim of this survey is to identify trends in database usage, as well as changing attitudes to MySQL following its acquisition by Oracle, and the competitive dynamic between MySQL and other databases, including NoSQL and NewSQL technologies.

There are just 15 questions to answer, spread over five pages, and the entire survey should take less than ten minutes to complete.

All individual responses are of course confidential. The results will be published as part of a major research report due during Q2.

Developer-Driven Databases

Even though I have come late to the party of professional development, relatively speaking, I am acutely aware of the conflict that seems to pervade the developer-DBA relationship. This is what I gather about why this is: DBAs used to be paid better that developers, and often this was because they were able to reduce the overall license and hardware costs of large database installations. Both the size and proprietary nature of databases made them incredibly expensive, so paying an individual gobs of money to make sure they ran efficiently and that the data was preserved was worth it.

Several trends have changed the playing field. The first is the arrival of small, commodity server hardware that makes mainframes or large servers unnecessary, and thus the cost is pushed down dramatically for most installations, while salaries for trained database professionals remained the same.

The second is the explosion of databases that do not (in …

NoSQL is What?

I found myself reading NoSQL is a Premature Optimization a few minutes ago and threw up in my mouth a little. That article is so far off base that I’m not even sure where to start, so I guess I’ll go in order.

In fact, I would argue that starting with NoSQL because you think you might someday have enough traffic and scale to warrant it is a premature optimization, and as such, should be avoided by smaller and even medium sized organizations.  You will have plenty of time to switch to NoSQL as and if it becomes helpful.  Until that time, NoSQL is an expensive distraction you don’t need.

Uhm… WHAT?!

I’ve spent more than a few years using MySQL and have been using some NoSQL systems for the last year or so in a fairly busy environment. And scaling is only one of the considerations that factor into …
