Version 1.5 of OrientDB Graph Database has just been released to the planet!

Hi everyone,
only 2 months after the release of v.1.4 (and only 1 month after the v.1.4.1 release), version 1.5 is now available for download!  

This release could actually be named 2.0 for all the various new features:

  • New PLOCAL (Paginated Local) storage engine.  In comparison with LOCAL, it’s more durable (no usage of MMAP) and supports better concurrency on parallel transactions.
  • New Hash Index type with better performance on lookups. It does not support ranges.
  • New “transactional” SQL command to execute commands inside a transaction. This is useful for the “create edge” SQL command, in order to avoid corruption of the graph
  • Import now migrates RIDs, allowing the ability to import database objects in a different one from the original 
  • Breadth first” strategy added on traversing (Java andSQL APIs)
  • Server can limit maximum live connections (to prevent DOS)
  • Fetch plan support in SQL statements and in binary protocol for synchronous commands too
  • Various bug fixes

For all the issues:
