MySQL on Cloud Storage: ClouSE upgrade made easy

Updating ClouSE can now be done with one command

With more than a thousand registered users worldwide, guiding customers through the upgrade process is getting hard, so we decided to automate the servicing steps.  Now the update-clouse script can be used to update ClouSE binaries to the current version.  This script ships with the ClouSE binary distribution.

Here is an example of updating ClouSE using the Webmin console.

MySQL 5.6: an inside perspective

MySQL 5.6 through the eyes of a custom storage engine MySQL plugin

MySQL is famous for its pluggable storage engine architecture which allows a DBA or an application developer to choose the right engine for the task. An application uses MySQL API and is isolated from all of the low-level implementation details at the storage level. As an example, the Cloud Storage Engine (ClouSE) enables existing MySQL applications to use cloud storage such as Amazon S3 or Google Cloud Storage to store its data. The application doesn’t need to be changed or even redeployed: with ClouSE, remote cloud storage will look like a better (ultra-scalable, durable, always-on) alternative to the local storage.

As you may already know, ClouSE now supports MySQL 5.6 release series.  See this announcement for more detail. Let’s go through the set of changes that were required on the ClouSE side in order to keep up with core MySQL 5.6 changes.

We had to adapt our code to compile and work with MySQL 5.6 while keeping 100% compatibility with MySQL 5.5. As much as we could, we tried to fix the code in a way that would work with both release series, but there are cases where the code has to be conditionally compiled for each release series.

Here is the list of MySQL 5.6 breaking changes and our solutions, in no particular order.

MySQL on Cloud Storage: do it yourself with one command

Cloud Storage Engine (ClouSE) installation and configuration is now fully automated. Try new ClouSE installer and you’ll have cloud storage access configured in no time.

OblakSoft is pleased to announce the release of Cloud Storage Engine (ClouSE) installer that can be used to deploy and configure ClouSE with your MySQL server. Now ClouSE can be deployed with just one command. The installer will guide the user through the configuration process, prompt for Cloud Storage connection parameters, and install ClouSE into MySQL.

Presented is a step-by-step guide for ClouSE installation and configuration, from downloading the binaries to running the installer. The guide was designed by request of WordPress-to-Cloud users, however it is fully applicable to any generic ClouSE installation.

The slides have notes, they are a little hard to discover with the SlideShare interface, look for a tab below the slide that looks like “Notes on Slide #”.

MySQL and WordPress welcome Google Cloud Storage

OblakSoft is pleased to announce that the Cloud Storage Engine for MySQL (ClouSE) now supports Google Cloud Storage.  Using MySQL to store data directly in Google Cloud Storage becomes a simple deployment choice: pick your Google Cloud Storage bucket and migrate any or all of your tables to the cloud.  We would like to thank Google storage team for their support and contributions.

This functionality opens Google Cloud Storage to millions of MySQL-based applications – cloud storage becomes a better alternative to local storage, no matter where you host the application, on premise or in the cloud.  Applications can now store data on Google’s infrastructure, and enjoy high availability, high durability and high scalability of Google Cloud Storage.

MySQL on Amazon S3: ClouSE version 1.0b.1.4 is released

OblakSoft is pleased to announce the release of ClouSE version 1.0b.1.4.  In this release we fixed some of the known ClouSE Beta limitations that required workarounds in some configurations.

In particular, now the popular BuddyPress WordPress plugin can store its tables in ClouSE without a patch that worked around the missing features.  If you’re using the patched version of BuddyPress 1.6.1 provided by us, you can now upgrade ClouSE and use the original BuddyPress sources.  Thank you for your patience and commitment!

MySQL BLOB meets Amazon S3: advanced Weblob features

Advanced Weblob operations help to use Weblobs most effectively.

Weblob recap

In an earlier post I introduced Weblobs.  Weblob is a new data type that is supported by the Cloud Storage Engine for MySQL (ClouSE).  To a database developer, a WEBLOB behaves (almost) like a regular BLOB.  However, in addition to the regular BLOB functionality, Weblobs can be downloaded directly from Amazon S3 by HTTP URLs.

In MySQL, a Weblob is expressed via a pair of BLOB fields that have a special naming convention: field_name$wblob and field_name$wblob_info.  The latter field is what provides the Weblob functionality.  It can be used to retrieve the direct Amazon S3 URL for the BLOB content.

But why does the field_name$wblob_info field have the $wblob_info suffix and not $wblob_url suffix?  Can it do more than just retrieve direct URLs?  It actually can.

ClouSE version 1.0b.1.3 and 64bit WordPress on S3 / Yapixx refresh is released

OblakSoft recommends upgrading ClouSE to the latest version 1.0b.1.3 that fixes an issue with some SELECT statements.  Previously some SELECT statements (e.g. using index_merge w/intersect query execution plans) may mistakenly miss records.

OblakSoft is also pleased to announce that 64-bit AMI of WordPress on S3 / Yapixx is now available.  We’ve got requests from customers who’d like to use the AMI in production, but didn’t want to run a 32-bit AMI, and had to build their own 64-bit AMI using our AMI as a reference.  Now they can use our standard fully configured ready-to-run 64-bit AMI directly as a starting platform for their WordPress on S3 production websites.

The software can be downloaded at http://www.oblaksoft.com/downloads/ for FREE.

The release notes are available here.
