Spin 1.20 (upcoming)

  • Refactored and cleaned up Maven module layout
  • moved ETL module to extension-support

Spin 1.19 (October 2011)

  • Nodes use new, tuned ExecutorService, resulting in 2x speedup when broadcasting to large (> ~60) downstream nodes. (Thanks to Sophia Cheng)
  • Split tools module into tools and tools-nodeps.  tools-nodeps contains all non-Spin-specific utility code that doesn't require any external dependencies beyond Java's standard lib.

Spin 1.18 (April 2011)

  • Added new node-side call: blockingQuery().
  • Added new client-side API SpinClient, which uses blockingQuery() to avoid polling.
  • Developer pain reduction: all Exceptions are now unchecked. Please report any checked Exceptions as bugs.
  • Codebook classes moved from dataaccess-core module to extension-support.
  • Agent class now implements an interface for easier mocking.

Spin 1.17 (March 2011)

  • Breaking API change: Nodes, Agents, and Queriers now return ResultSets with metadata instead of Collection<Result>s (BASE-666). (Clint Gilbert; requested by Bill Simons)
  • Routing change: Nodes now broadcast queries with unknown query types (BASE-664).  This removes the need for loading up NoopQueryActions for routing-only nodes. (Clint Gilbert)
  • Less-noisy output on log4j initialization failure (BASE-668). (Requested by Bill Simons)
  • Developer pain reduction: all Exceptions in org.spin.tools are now unchecked. (Thanks to David Ortiz for starting this off)

Spin 1.16 (February 2011)

  • Support for multiple CA Certs (David Ortiz)
  • Removed JAXB dependencies - Java 1.6.0_4+ is now required. (Justin Quan)
  • Fixed cross-timezone digital signature verification bug (Clint Gilbert and Sophia Cheng)
  • keystore.xml returns to pre-Spin 1.14 format - prefer boolean flags for nicer XML. (Justin Quan)
  • No labels
