[Bigdata-developers] Lexicon branch (physical schema change breaks binary compability).

[Bryan T. <br...@sy...>]

All,

We are preparing to close out the lexicon branch, merging it into the trunk and then tag a release.  The lexicon branch incorporates physical schema changes which allow us to inline XSD numerics and some other datatypes into the statement indices.  This will be a huge performance win for scale-out analytic queries.

This change set BREAKS BINARY COMPATIBILITY with existing triple and quads store instances.  Since every tuple in the lexicon and statement indices is different under the new physical schema, the easiest way to migrate is to export/import.

In order to support existing installations, I have created a NO_INLINING_BRANCH. This branch starts at r3285.  This is a branch from the trunk immediately prior to merging in the physical schema change required to support inlining of XSD numeric and other datatypes into the statement indices.

I plan to prepare a release including including the change set from the lexicon branch on Monday / Tuesday.

Thanks,
Bryan
