I'm pleased to announce Scylla Rust Driver 0.3.0, an asynchronous CQL
driver for Rust, fully compatible with Apache Cassandra™!
=== Notable changes ===
* Connection management is heavily revamped:
> a configurable pool of connections is kept per node or per shard
(Scylla only)
> shard awareness is now also supported without a dedicated
shard-aware port (Scylla only)
> several optimizations were applied to make this layer more robust
* A CachingSession class is introduced - it allows creating a session
which automatically prepares its statements
and maintains them in a local cache.
* Colummn values can now be extracted from result rows by the column
name, not only by their index.
* Handling user defined types is improved - when a new field is added
to the type, the driver is now still capable of reading the values.
* A ValueList derive macro is now available - when it's applied to a
struct, an instance of this struct can be used as a list of values in
queries.
* Client-side timestamps can now be defined for queries.
* Tuples with null elements are now handled correctly.
* Serial consistency level (for lightweight transactions) is now split
into a separate type in order to make it clear that it should not be
mixed with regular consistency level.
* Shorter topology names, e.g. "SimpleStrategy" are now recognized and
accepted.
* Internal queries now use paging internally in order to avoid
overloading the cluster and the driver with large requests.
* Serialization path got optimized.
+ lots of other fixes and improvements
