Note on non-production status: due to available testing time from our volunteers, core and datastore changes for this release did not meet our usual bar for release testing. As a result, we've decided to publish this release as-is and put effort towards reestablishing testing for the next release cycle. Users interested in making use of this release are advised to check on issue #1265 for any status updates. If you get to test out one of the bindings changed in this release, please leave a note on that issue so that the work isn't repeated.

Incompatible Changes

  • Azure Document DB has been removed (#1295)

Known Issues

  • The mongodb binding does not honor the maxPoolSize=XX parameter and instead opens a connection per client thread. (see #317)
  • Mongodb binding use with AWS DocumentDB requires manually converting SSL CA format (see #1314)
  • Datastore drivers that lack timeouts may result in YCSB failing to honor the maxexecutiontime parameter. (see #618)
  • "Latest" distribution does not work properly on update transactions. (see #640)
  • Accumulo client currently always claims success even when the record it's supposed to operate on (e.g. for a read) doesn't exist. (see #699)
  • JDK 9 and JDK 10 are not supported. (see #704)
  • ArangoDB client bindings fail to work with ArangoDB authentication (see #1155)
  • HBase 2.0 client bindings doesn't include an slf4j logging-binding and so doesn't provide log messages from the client library (see #1173)
  • The Accumulo client bindings do not work with kerberos enabled clusters (see #1211)
