Ideas for a new structure to distribute builds in the mirror network

The number of native language teams are increasing and therefore install sets for more languages of (OOo) are possible to release. The result is that more and more space on the mirrors network is needed to cover such demand by the contributors and the users. We want to endorse this demand by providing more languages.

The demand will increase ... :

  • on /extended to ca. 300 GB (for RCs, Beta, Dev Builds, L10N, ISO files) and
  • on /stable and /localized to ca. 200 GB.

In order to not increase the mirror sizes on purely it could be an alternative to split some parts into packages:

  • The /stable part contains en-US builds only. As this is very interesting for the very most it it will stay as it is.
  • The /localized part contains all languages regardless if you want to distribute them in the region you are working. But what about splitting this into packages?

  1. Define a package that contains languages by coherent regions
    We can split all languages into reasonable packages and you can choose which ones you like to have on your mirror. With this method you can decide on your own about the total size you need. When we need more space in total you can try to hold your current size with choosing only a set of packages.

  2. Define a package that contains languages by their download rate
    It's also possible to look at the download rate for all languages and define packages depending on this. So, the most downloaded languages can be in one package, the second most in another package and so on.

  3. Do you have another idea?
    Of course we do not want to predefine the packages that you have to choose. We can speak about the number of languages and/or the total file sizes for each package. Or maybe about another structure? At the end you have the decision on your own how many languages and MB's you want to distribute through your servers.

  • The last part is /extended which contains mostly Beta / RC's, Developer Snapshots and L10N relevant files. Also this part needs to be increased as we expect larger RC's in the future. E.g., the newest OOo 3.3.0 RC 3 is about 78 GB. However, only the mirrors that support the extended set are affected and these are mostly very powerful servers.
  • Disk space on archive mirrors will also need to be upgraded as we want to keep every legacy product release there.

If you still want to provide the full set of files there is nothing to change. Only if you want to distribute a part of the set you have to select the respective packages and to change/extend your rsync scripts.

Please give us your comment on this. Either via mail or in this Wiki. We are open to your opinions. Thank you.

Big picture of the new structure

Description Size
/stable/<version>/... en-US builds only
/localized/<language code>/<version>/... localized builds
/extended/... RCs, Beta, Dev Builds, L10N, ISO files
/packages/<package number/... the numbered packages from the tables below

When will the new structure go live?

Deployment for OOo 3.3.0

The upcoming OOo 3.3.0 release will have full installation sets for up to 41 languages (avg. 166 MB per file) and language packs for up to 70 languages (avg. 20 MB per file), so in total approx. 78 GB.

For this we will create the structure and hard-link the localized builds into the package subdirs, even when the packages will be filled with just a few languages or nothing at the moment. The advantage is that the package structure is already available and does not need to be changed (or at least not too much) when the other languages can be released.

Deployment for the future

For the future we plan to build release files for more languages and the total size of a release could of course increase like mentioned above when they got tested and approved. However, the package structure will remain the same but with more files in the subdirs.

Some statistical sizes

File sizes are calculated with OOo 3.2.1 as basis. All other numbers are reflecting the future:

Description Size
Current total size of the /stable part (GB) 7
Current total size of the /localized part (GB) 44
Current total size of the /extended part (GB) 90
Average file size of a full install build (MB) 162
Average file size of a langpack build (MB) 21
Full install platforms (#) 11
Langpack platforms (#) 9
Languages full builds (#) 100
Languages langpacks (#) 100
Future total size of the /stable part (GB) 2
Future total size of the /localized part (GB) 200
Future total size of the /extended part (GB) 300
