DataStax Ruby Driver 3.0.2

Apache Cassandra 2.2 and 3.0 compatible release

Bug Fixes:

• RUBY-219 Sometimes get stack trace in metadata.rb due to failure in SortedSet initialization.
• RUBY-220 Improve support for custom types.
• RUBY-231 Driver ignores explicitly specified nil timeout (to indicate no time limit on query execution).
• RUBY-233 Client timeout errors are retried for non-idempotent statements.

DataStax Ruby Driver 3.0.0

Apache Cassandra 2.2 and 3.0 compatible release

Features:

• Increased default request timeout (the timeout option to Cassandra.cluster), from 10 seconds to 12 seconds because C* defaults to a 10 second timeout internally. The extra two seconds is buffer so that the client can report the timeout in the server. This is also consistent with the Java driver.
• Expand :client_timestamps cluster configuration option to allow user to specify his own generator for client timestamps.
• Add protocol_version configuration option to allow the user to force the protocol version to use for communication with nodes.
• Expose listen_address and broadcast_address in Cassandra::Host if available.
• Add support for materialized views in the schema metadata.
• Add support for Cassandra indexes in the schema metadata.
• Add or expose the id, options, keyspace, partition_key, clustering_columns, and clustering_order attributes to table and view schema objects.
• Add crc_check_chance and extensions attributes to ColumnContainer options.
• Make cluster configuration options list publicly available. (Thanks, Evan Prothro!)
• Add connections_per_local_node, connections_per_remote_node, requests_per_connection cluster configuration options to tune parallel query execution and resource usage.
• Add Cassandra::Logger class to make it easy for users to enable debug logging in the client.
• Added optional time out to Cassandra::Future#get
• Allow skipping bound values or using Cassandra::UNSET explicitly.
• Add support for smallint, tinyint, date (Cassandra::Date) and time (Cassandra::Time) data types.
• Add new errors: Cassandra::Errors::ReadError, Cassandra::Errors::WriteError and Cassandra::Errors::FunctionCallError.
• Include schema metadata for User Defined Functions and User Defined Aggregates.
• Include client ip addresses in request traces, only on Cassandra 3.x.
• Add new retry policy decision Cassandra::Retry::Policy#try_next_host.
• Support specifying statement idempotence with the new :idempotent option when executing.
• Support sending custom payloads when preparing or executing statements using the new :payload option.
• Expose custom payloads received with responses on server exceptions and Cassandra::Execution::Info instances.
• Expose server warnings on server exceptions and Cassandra::Execution::Info instances.

Breaking Changes:

• Cassandra::Future#join is now an alias to Cassandra::Future#get and will raise an error if the future is resolved with one.
• Default consistency level is now LOCAL_ONE.
• Enable tcp no-delay by default.
• Unavailable errors are retried on the next host in the load balancing plan by default.
• Statement execution no longer retried on timeouts, unless :idempotent => true has been specified when executing.
• The Datacenter-aware load balancing policy (Cassandra::LoadBalancing::Policies::DCAwareRoundRobin) defaults to using nodes in the local DC only. In prior releases, the policy would fall back to remote nodes after exhausting local nodes. Specify a positive value (or nil for unlimited) for max_remote_hosts_to_use when initializing the policy to allow remote node use.

Bug Fixes:

• RUBY-120 Tuples and UDTs can be used in sets and hash keys.
• RUBY-143 Retry querying system table for metadata of new hosts when prior attempts fail, ultimately enabling use of new hosts.
• RUBY-150 Fixed a protocol decoding error that occurred when multiple messages are available in a stream.
• RUBY-151 Decode incomplete UDTs properly.
• RUBY-154 Improve batch request performance, which had regressed in 3.0.0 beta1.
• RUBY-155 Request timeout timer should not include request queuing time.
• RUBY-156 Do not drop response frames that follow a frame containing a warning.
• RUBY-161 Protocol version negotiation in mixed version clusters should not fall back to v1 unless it is truly warranted.
• RUBY-180 Column ordering is not deterministic in Table metadata.
• RUBY-185 Internal columns in static-compact and dense tables should be ignored.
• RUBY-186 Custom type column metadata should be parsed properly for C* 3.x schemas.
• RUBY-207 Get NoMethodError when handling a write-timeout error using a downgrading consistency retry policy.
• RUBY-214 Client timestamps in JRuby are not fine-grained enough, causing timestamp collisions and lost rows in C*.

DataStax Ruby Driver 2.1.6

Apache Cassandra 2.1 compatible release

Bug Fixes:

• RUBY-202 Allow password authenticator to be used for LDAP authentication. This is actually a backport of RUBY-169 for the 3.0.0 release.
