The H-Store project is releasing the latest version of its experimental OLTP database management system. This version contains a large number of speed and stability improvements. The next release will contain mostly new features.<\/p>\n

Major highlights of this release:<\/p>\n

    \n
  1. Significant speed optimizations for single-partition transactions. [cf9be4a]<\/a> [c67babd]<\/a> [f2659fd]<\/a> [0425253]<\/a> [243f99d]<\/a> [5abd178]<\/a>\n
  2. Fixed several memory leaks for aborted\/read-only transactions. [ddf2f23]<\/a> [e429821]<\/a>\n
  3. Fixed several stability issues when transactions share lock-free data structures [4956be9]<\/a>\n
  4. Fixed predicate\/aggregate pushdowns for distributed query plans [4956be9]<\/a> [31eff68]<\/a>\n
  5. Restored the ability for transactions to return the proper status codes on failures that mimic VoltDB’s protocol. [ae4a6a4]<\/a> [f374d49]<\/a>\n
  6. H-Store’s Fabric<\/a> automatic deployment script for EC2 now supports multiple concurrent “virtual” clusters. This allows you to easily assign instances to independent clusters under a single AWS account. [1202f4e]<\/a>\n
  7. Restored preliminary support for VoltDB’s regression test suite. [1f4f465]<\/a> [c434fa2]<\/a> [1945aba0]<\/a>\n
