Advice on Blob Storage?
by Michael McFadden 15 Oct '15

15 Oct '15

This may be more of a zodb / relstorage question - I hope it's ok to ask on the Zope list. I'm seeing behavior using relstorage and blobs that I didn't expect: If I upload a large file, say 2 gigs, I am noticing that our SQL database also grows by 2 Gigs, along with the blob storage. After a pack, the space is reclaimed on the SQL side, and everyone is happy. FWIW - it's videos that are doing this. I am pretty sure it's the undo log that's growing, based on the fact that a pack reclaims the space. Can this behavior be turned off for a specific field or content type? So undo logs are preserved for everything BUT this monster of a content type? Seems strange to do this tho. Are there other alternatives, like calling .pack() directly on the field's storage after it's set? Our problem is that our sql database grows to a huge size between our weekly packs, and backups of the sql dumps are becoming unmanageable. Our blob backups are ready to deal with this kind of size, but not the sql backups. ---------- Going deeper down the rabbit hole, although I don't think it's relevant, is the fact that I hacked and replaced the storage class for the field. Instead of using AnnotationStorage - which I found used as default for ImageField - I intercept the data during storage.set(), ship it out to a separate storage facility, and replace the data with a happy message "This is not where your data is" which is then written to the blobs. It works just great - keeping our blob storage growth from going crazy. If you try to 'download' the file from Plone, you'll get the text file with the happy message. Now that I've been shown that the Blob Storage is functioning just fine, but the SQL storage size is going off the charts, I hope I'm not back at square one. The goal is to allow users to think they are uploading 4Gb videos into Plone, when under the covers, we're actually shipping the video files off to some fancy off-site storage. (Akamai) So we don't have to store them and back them up on-site, and our blob directories remain manageable in size. The storage hack can be seen here: https://github.com/RadioFreeAsia/rfa.kaltura/blob/master/rfa/kaltura/storag… I'm not proud of it, but it works. -- Mike McFadden Radio Free Asia Technical Operations Division 2025 M Street NW Washington DC 20036 USA This e-mail message is intended only for the use of the addressee and may contain information that is privileged and confidential.

ANN: eGenix mxODBC Plone/Zope Database Adapter 2.2.3
by eGenix Team: M.-A. Lemburg 14 Sep '15

14 Sep '15

________________________________________________________________________ ANNOUNCING mxODBC Plone/Zope Database Adapter Version 2.2.3 for the Plone CMS and Zope server platform Available for Plone 4.0-4.3 and Plone 5.0, Zope 2.12 and 2.13, on Windows, Linux, Mac OS X, FreeBSD and other platforms This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Zope-DA-2.2.3-GA.html ________________________________________________________________________ INTRODUCTION The eGenix mxODBC Zope DA allows you to easily connect your Zope or Plone CMS installation to just about any database backend on the market today, giving you the reliability of the commercially supported eGenix product mxODBC and the flexibility of the ODBC standard as middle-tier architecture. The mxODBC Zope Database Adapter is highly portable, just like Zope itself, and provides a high performance interface to all your ODBC data sources, using a single well-supported interface on Windows, Linux, Mac OS X, FreeBSD and other platforms. This makes it ideal for deployment in ZEO Clusters and Zope hosting environments where stability and high performance are a top priority, establishing an excellent basis and scalable solution for your Plone CMS. Product page: http://www.egenix.com/products/zope/mxODBCZopeDA/ ________________________________________________________________________ NEWS The 2.2.3 release of our mxODBC Zope/Plone Database Adapter product is a patch level release of the popular ODBC database interface for Plone and Zope. It includes these enhancements and fixes: Feature Updates --------------- * We have integrated a new option to force serialized connects on a per Zope connection object basis. This can be used to work around bugs in ODBC drivers which are not fully thread-safe in the connect phase. The option is disabled per default. Driver Compatibility Enhancements --------------------------------- * ODBC driver compatibility updated. Upgraded to the latest mxODBC 3.3.5 release, adding compatibility enhancements for MS SQL Server. See the mxODBC 3.3.5 release announcements for full details. Installation Enhancements ------------------------- * Added pip install compatibility to mxODBC Zope DA by creating prebuilt archives and uploading a web installer to PyPI. This can be useful if you are installing Zope or Plone using a requirements.txt type approach, e.g. using pip install ThreadLock Products.ZSQLMethods egenix-mxodbc-zopeda * Enabled creating wheels from the prebuilt archives, which helps when running pip with the wheels package installed. pip then tries to build wheels during installation and caches them for future reuse. The complete list of changes is available on the mxODBC Zope DA changelog page. http://www.egenix.com/products/zope/mxODBCZopeDA/changelog.html mxODBC Zope DA 2.2.0 was released on 2014-12-11.
