Changelog

4.0.1

Bug fix:

  • Fix the queryFailed event so it includes an error parameter.

4.0.0

This major release is geared toward internal performance improvements and removing some legacy code cruft relating to the now-defunct dual driver support.

BREAKING:

  • Priam now requires node 10.17 or node 12.3 or greater so it can take advantage of async iterator support. For some reason, node 11 is incompatible.
  • In olden days, priam supported two underlying Cassandra drivers. This is no-longer the case, so some effort has been done to remove the cruft in the code for this dual support. One of these changes removes the translation of the old helenus driver config options to those compatible with cassandra-driver. Config options in priam are now aligned directly with the config options of cassandra-driver.
  • Errors are now emitted correctly when writing to a stream. This means you may now need to attach error handlers to your streams to avoid unhandled error exceptions.
  • Undocumented private methods have now been prefixed with underscores; if your code was calling these undocumented methods directly, those methods may now have been renamed or removed.
  • Some cases where error would be emitted through streams or callbacks have been changed to throw immediately in the case of caller error. For example, passing a named query that does not exist will throw immediately to the caller.

Features:

  • Query methods now all support callbacks, Promises, stream writing, and async iterators options.
  • connect and close methods now support Promises
  • All query result options use retry mechanisms; before the stream option did not.

Performance:

  • Streaming functionality has been streamlined; native node streams are now used instead of third-party wrappers, and the number of intermediate streams wrappers have been reduced. You may now use the async iterable options to avoid even more node streaming overhead.

See the migration from 3.x to 4.x to assist your efforts into migrating to version 4.x.

3.1.0

  • Error objects will now return query metadata, including parameters. In production environments, it is recommended that the parameter values be excluded from logs.

3.0.0

Features:

  • localDataCenter is now a required field in cassandra-driver version 4.

2.2.0

Features:

  • Support a localDataCenter config setting to use in the load balancing policy

2.0.0

Features:

  • Updated cassandra-driver to latest version, handle new data type coercion. Breaking Changes:
  • Removed helenus dependency (deprecated in 1.2.0).

1.2.1

  • Added retry module from PR #47.

1.2.0

  • Resolved #44 (issue with USING TIMESTAMP on individual statementes within batch queries).
  • Fixed an issue with subtypes being dropped from collection type hints.
  • Downgrade helenus library to an optional dependency.

1.1.3

  • Fix issue with BOM marks inside of named queries.

1.1.2

  • Update cassandra-driver connection error logging.

1.1.1

  • Add emulated streaming support for helenus driver.

1.1.0

  • Add streaming support with Query.stream() or db.cql() for cassandra-driver.

1.0.0

  • Fix keyspace option when using multiple instances. This is a breaking change if you relied on the undocumented instance.pools.default property being available.

0.9.7

  • Attach cql to error objects generated by query execution.

0.9.6

  • Add support for routingIndexes when using TokenAwarePolicy.

0.9.5

  • Add better error handling for cassandra-driver.

0.9.4

  • Strip schema metadata from result sets over binary protocol v1.

0.9.3

  • Adjust stringify for numeric bigint values.

0.9.2

  • Fix parameterized queries over binary protocol v1.

0.9.1

  • Dependency updates.

0.9.0

  • Removed node-cassandra-cql in favor of cassandra-driver.

0.8.17

  • Batch.execute no longer yields an error when the batch is empty.

0.8.16

  • Simplified result set transformation for node-cassandra-cql drivers.

0.8.15

  • Add isBatch and isQuery methods to base driver.

0.8.14

  • Fix resultTransformer bug when query generates an error.

0.8.13

  • Fix Batch.add() when given empty Batch or Query objects.

0.8.12

  • Remove github dependency via priam-connection-cql module.
  • Added versioning logic around cqlVersion to use the appropriate driver.

0.8.11

  • Coerce timestamp hinted parameters for node-cassandra-cql to Date objects from string or number.

0.8.10

  • Batch.add() can now take an Array argument.

0.8.9

  • Fix usage of Batch.addBatch() in pre-2.0 Cassandra environments that do not support DML-level timestamps.

0.8.8

  • Fixed bug where Query.single() and Query.first() would return empty array instead of null on empty result sets.

0.8.7

  • Fixed bug which caused boolean values to not be returned when their value is false

0.8.6

  • Fixed bug which caused resultTransformers to not execute

0.8.5

  • Changed config to look up consistency level enum if given a string
  • Added resultTransformers to drivers and queries-- synchronous functions that are mapped over query results
  • Query consistency is set to driver's at instantiation, rather than being looked up at execution if not present
  • Added query method to base driver, alias for cql

0.8.4

  • Modified Batch.execute() to send timestamps as parameters instead of CQL strings.

0.8.3

  • Added Query.single(), Query.first(), and Query.all() enhancements.

  • Revert back to Promises v1.

0.7.0

  • Update to latest version of Promises (q.js).
  • Potential breaking change - JSON is no longer auto-deserialized. See the Executing CQL section for more information. Use object data types if auto-deserialization is required on specific fields, or use deserializeJsonStrings option to detect JSON as 0.6.x and prior did.
