[RELEASE] Java driver 3.0.4

[Olivier Michallat]

We've just release a new patch release in the 3.0.x series.

The most important ticket is a refactoring of our connection pool (JAVA-893), which addresses a shortcoming of the previous implementation: acquiring a connection from the pool is now fully non-blocking, which means session.executeAsync won't block the calling thread under any circumstance. In particular, you can now safely run async queries on a session connected to a keyspace.

Other notable fixes include a corruption issue when frames exceeded the maximum size allowed by the protocol (JAVA-1292), and performance optimizations for compression (JAVA-1263).

Here's the full changelog:

- [improvement] JAVA-1246: Driver swallows the real exception in a few cases

- [improvement] JAVA-1261: Throw error when attempting to page in I/O thread.

- [bug] JAVA-1258: Regression: Mapper cannot map a materialized view after JAVA-1126.

- [bug] JAVA-1101: Batch and BatchStatement should consider inner statements to determine query idempotence

- [improvement] JAVA-1262: Use ParseUtils for quoting & unquoting.

- [improvement] JAVA-1275: Use Netty's default thread factory

- [bug] JAVA-1285: QueryBuilder routing key auto-discovery should handle case-sensitive column names.

- [bug] JAVA-1283: Don't cache failed query preparations in the mapper.

- [improvement] JAVA-1277: Expose AbstractSession.checkNotInEventLoop.

- [bug] JAVA-1272: BuiltStatement not able to print its query string if it contains mapped UDTs.

- [bug] JAVA-1292: 'Adjusted frame length' error breaks driver's ability to read data.

- [improvement] JAVA-1293: Make DecoderForStreamIdSize.MAX_FRAME_LENGTH configurable.

- [improvement] JAVA-1053: Add a metric for authentication errors

- [improvement] JAVA-1263: Eliminate unnecessary memory copies in FrameCompressor implementations.

- [improvement] JAVA-893: Make connection pool non-blocking

As usual, the driver is available from Maven and as a binary tarball; see the "Getting the driver" section in our online documentation:

Thanks a bunch for your hard work!

Do you have an ETA for porting and releasing those changes in the 3.1 branch?

Cheers

Hi,

No ETA at this point, but we'll definitely release a 3.1.1 as soon as possible to merge those changes.
