| |
| * cqlengine: a major improvement on queryset has been introduced. It |
| is a lot more efficient to iterate large datasets: the rows are |
| now fetched on demand using the driver pagination. |

| now executes a "SELECT COUNT(*)" of the query rather than returning |
| the size of the internal result_cache (loaded rows). On large |
| queryset, you might want to avoid using them due to the performance |
| cost. Note that trying to access objects using list index/slicing |
| with negative indices also requires a count to be |
| executed. |

| 2.1.0b1 |
| ======= |
| July 11, 2014 |
| |
| This release adds support for Cassandra 2.1 features, including version |
| 3 of the native protocol. |
| |
| Features |
| -------- |
| * When using the v3 protocol, only one connection is opened per-host, and |
| throughput is improved due to reduced pooling overhead and lock contention. |
| * Support for user-defined types (Cassandra 2.1+) |
| * Support for tuple type in (limited usage Cassandra 2.0.9, full usage |
| in Cassandra 2.1) |
| * Protocol-level client-side timestamps (see Session.use_client_timestamp) |
| * Overridable type encoding for non-prepared statements (see Session.encoders) |
| * Configurable serial consistency levels for batch statements |
| * Use io.BytesIO for reduced CPU consumption (github #143) |
| * Support Twisted as a reactor. Note that a Twisted-compatible |
| API is not exposed (so no Deferreds), this is just a reactor |
| implementation. (github #135, PYTHON-8) |
| |
| Bug Fixes |
| --------- |
| * Fix references to xrange that do not go through "six" in libevreactor and |
| geventreactor (github #138) |
| * Make BoundStatements inherit fetch_size from their parent |
| PreparedStatement (PYTHON-80) |
| * Clear reactor state in child process after forking to prevent errors with |
| multiprocessing when the parent process has connected a Cluster before |
| forking (github #141) |
| * Don't share prepared statement lock across Cluster instances |
| * Format CompositeType and DynamicCompositeType columns correctly in |
| CREATE TABLE statements. |
| * Fix cassandra.concurrent behavior when dealing with automatic paging |
| (PYTHON-81) |
| * Properly defunct connections after protocol errors |
| * Avoid UnicodeDecodeError when query string is unicode (PYTHON-76) |
| * Correctly capture dclocal_read_repair_chance for tables and |
| use it when generating CREATE TABLE statements (PYTHON-84) |
| * Avoid race condition with AsyncoreConnection that may cause messages |
| to fail to be written until a new message is pushed |
| * Make sure cluster.metadata.partitioner and cluster.metadata.token_map |
| are populated when all nodes in the cluster are included in the |
| contact points (PYTHON-90) |
| * Make Murmur3 hash match Cassandra's hash for all values (PYTHON-89, |
| github #147) |
| * Don't attempt to reconnect to hosts that should be ignored (according |
| to the load balancing policy) when a notification is received that the |
| host is down. |
| * Add CAS WriteType, avoiding KeyError on CAS write timeout (PYTHON-91) |
| |
| 2.0.2 |
| ===== |
| June 10, 2014 |
| |
| Bug Fixes |
| --------- |
| * Add six to requirements.txt |
| * Avoid KeyError during schema refresh when a keyspace is dropped |
| and TokenAwarePolicy is not in use |
| * Avoid registering multiple atexit cleanup functions when the |
| asyncore event loop is restarted multiple times |
| * Delay initialization of reactors in order to avoid problems |
| with shared state when using multiprocessing (PYTHON-60) |
| * Add python-six to debian dependencies, move python-blist to recommends |
| * Fix memory leak when libev connections are created and |
| destroyed (github #93) |
| * Ensure token map is rebuilt when hosts are removed from the cluster |
| |
| 2.0.1 |
| ===== |
| May 28, 2014 |
| |
| Bug Fixes |
| --------- |
| * Fix check for Cluster.is_shutdown in in @run_in_executor |
| decorator |
| |
| 2.0.0 |
| ===== |
| May 28, 2014 |
| |
| Features |
| -------- |
| * Make libev C extension Python3-compatible (PYTHON-70) |
| * Support v2 protocol authentication (PYTHON-73, github #125) |
| |
| Bug Fixes |
| --------- |
| * Fix murmur3 C extension compilation under Python3.4 (github #124) |
| |
| Merged From 1.x |
| --------------- |
| |
| Features |
| ^^^^^^^^ |
| * Add Session.default_consistency_level (PYTHON-14) |
| |
| Bug Fixes |
| ^^^^^^^^^ |
| * Don't strip trailing underscores from column names when using the |
| named_tuple_factory (PYTHON-56) |
| * Ensure replication factors are ints for NetworkTopologyStrategy |
| to avoid TypeErrors (github #120) |
| * Pass WriteType instance to RetryPolicy.on_write_timeout() instead |
| of the string name of the write type. This caused write timeout |
| errors to always be rethrown instead of retrying. (github #123) |
| * Avoid submitting tasks to the ThreadPoolExecutor after shutdown. With |
| retries enabled, this could cause Cluster.shutdown() to hang under |
| some circumstances. |
| * Fix unintended rebuild of token replica map when keyspaces are |
| discovered (on startup), added, or updated and TokenAwarePolicy is not |
| in use. |
| * Avoid rebuilding token metadata when cluster topology has not |
| actually changed |
| * Avoid preparing queries for hosts that should be ignored (such as |
| remote hosts when using the DCAwareRoundRobinPolicy) (PYTHON-75) |
| |
| Other |
| ^^^^^ |
| * Add 1 second timeout to join() call on event loop thread during |
| interpreter shutdown. This can help to prevent the process from |
| hanging during shutdown. |
| |
| 2.0.0b1 |
| ======= |
| May 6, 2014 |
| |
| Upgrading from 1.x |
| ------------------ |
| Cluster.shutdown() should always be called when you are done with a |
| Cluster instance. If it is not called, there are no guarantees that the |
| driver will not hang. However, if you *do* have a reproduceable case |
| where Cluster.shutdown() is not called and the driver hangs, please |
| report it so that we can attempt to fix it. |
| |
| If you're using the 2.0 driver against Cassandra 1.2, you will need |
| to set your protocol version to 1. For example: |
| |
| cluster = Cluster(..., protocol_version=1) |
| |
| Features |
| -------- |
| * Support v2 of Cassandra's native protocol, which includes the following |
| new features: automatic query paging support, protocol-level batch statements, |
| and lightweight transactions |
| * Support for Python 3.3 and 3.4 |
| * Allow a default query timeout to be set per-Session |
| |
| Bug Fixes |
| --------- |
| * Avoid errors during interpreter shutdown (the driver attempts to cleanup |
| daemonized worker threads before interpreter shutdown) |
| |
| Deprecations |
| ------------ |
| The following functions have moved from cassandra.decoder to cassandra.query. |
| The original functions have been left in place with a DeprecationWarning for |
| now: |
| |
| * cassandra.decoder.tuple_factory has moved to cassandra.query.tuple_factory |
| * cassandra.decoder.named_tuple_factory has moved to cassandra.query.named_tuple_factory |
| * cassandra.decoder.dict_factory has moved to cassandra.query.dict_factory |
| * cassandra.decoder.ordered_dict_factory has moved to cassandra.query.ordered_dict_factory |
| |
| Exceptions that were in cassandra.decoder have been moved to cassandra.protocol. If |
| you handle any of these exceptions, you must adjust the code accordingly. |
| |
| 1.1.2 |
| ===== |
| May 8, 2014 |
| |
| Features |
| -------- |
| * Allow a specific compression type to be requested for communications with |
| Cassandra and prefer lz4 if available |
| |
| Bug Fixes |
| --------- |
| * Update token metadata (for TokenAware calculations) when a node is removed |
| from the ring |
| * Fix file handle leak with gevent reactor due to blocking Greenlet kills when |
| closing excess connections |
| * Avoid handling a node coming up multiple times due to a reconnection attempt |
| succeeding close to the same time that an UP notification is pushed |
| * Fix duplicate node-up handling, which could result in multiple reconnectors |
| being started as well as the executor threads becoming deadlocked, preventing |
| future node up or node down handling from being executed. |
| * Handle exhausted ReconnectionPolicy schedule correctly |
| |
| Other |
| ----- |
| * Don't log at ERROR when a connection is closed during the startup |
| communications |
| * Mke scales, blist optional dependencies |
| |
| 1.1.1 |
| ===== |
| April 16, 2014 |
| |
| Bug Fixes |
| --------- |
| * Fix unconditional import of nose in setup.py (github #111) |
| |
| 1.1.0 |
| ===== |
| April 16, 2014 |
| |
| Features |
| -------- |
| * Gevent is now supported through monkey-patching the stdlib (PYTHON-7, |
| github issue #46) |
| * Support static columns in schemas, which are available starting in |
| Cassandra 2.1. (github issue #91) |
| * Add debian packaging (github issue #101) |
| * Add utility methods for easy concurrent execution of statements. See |
| the new cassandra.concurrent module. (github issue #7) |
| |
| Bug Fixes |
| --------- |
| * Correctly supply compaction and compression parameters in CREATE statements |
| for tables when working with Cassandra 2.0+ |
| * Lowercase boolean literals when generating schemas |
| * Ignore SSL_ERROR_WANT_READ and SSL_ERROR_WANT_WRITE socket errors. Previously, |
| these resulted in the connection being defuncted, but they can safely be |
| ignored by the driver. |
| * Don't reconnect the control connection every time Cluster.connect() is |
| called |
| * Avoid race condition that could leave ResponseFuture callbacks uncalled |
| if the callback was added outside of the event loop thread (github issue #95) |
| * Properly escape keyspace name in Session.set_keyspace(). Previously, the |
| keyspace name was quoted, but any quotes in the string were not escaped. |
| * Avoid adding hosts to the load balancing policy before their datacenter |
| and rack information has been set, if possible. |
| * Avoid KeyError when updating metadata after droping a table (github issues |
| #97, #98) |
| * Use tuples instead of sets for DCAwareLoadBalancingPolicy to ensure equal |
| distribution of requests |
| |
| Other |
| ----- |
| * Don't ignore column names when parsing typestrings. This is needed for |
| user-defined type support. (github issue #90) |
| * Better error message when libevwrapper is not found |
| * Only try to import scales when metrics are enabled (github issue #92) |
| * Cut down on the number of queries executing when a new Cluster |
| connects and when the control connection has to reconnect (github issue #104, |
| PYTHON-59) |
| * Issue warning log when schema versions do not match |
| |
| 1.0.2 |
| ===== |
| March 4, 2014 |
| |
| Bug Fixes |
| --------- |
| * With asyncorereactor, correctly handle EAGAIN/EWOULDBLOCK when the message from |
| Cassandra is a multiple of the read buffer size. Previously, if no more data |
| became available to read on the socket, the message would never be processed, |
| resulting in an OperationTimedOut error. |
| * Double quote keyspace, table and column names that require them (those using |
| uppercase characters or keywords) when generating CREATE statements through |
| KeyspaceMetadata and TableMetadata. |
| * Decode TimestampType as DateType. (Cassandra replaced DateType with |
| TimestampType to fix sorting of pre-unix epoch dates in CASSANDRA-5723.) |
| * Handle latest table options when parsing the schema and generating |
| CREATE statements. |
| * Avoid 'Set changed size during iteration' during query plan generation |
| when hosts go up or down |
| |
| Other |
| ----- |
| * Remove ignored ``tracing_enabled`` parameter for ``SimpleStatement``. The |
| correct way to trace a query is by setting the ``trace`` argument to ``True`` |
| in ``Session.execute()`` and ``Session.execute_async()``. |
| * Raise TypeError instead of cassandra.query.InvalidParameterTypeError when |
| a parameter for a prepared statement has the wrong type; remove |
| cassandra.query.InvalidParameterTypeError. |
| * More consistent type checking for query parameters |
| * Add option to a return special object for empty string values for non-string |
| columns |
| |
| 1.0.1 |
| ===== |
| Feb 19, 2014 |
| |
| Bug Fixes |
| --------- |
| * Include table indexes in ``KeyspaceMetadata.export_as_string()`` |
| * Fix broken token awareness on ByteOrderedPartitioner |
| * Always close socket when defuncting error'ed connections to avoid a potential |
| file descriptor leak |
| * Handle "custom" types (such as the replaced DateType) correctly |
| * With libevreactor, correctly handle EAGAIN/EWOULDBLOCK when the message from |
| Cassandra is a multiple of the read buffer size. Previously, if no more data |
| became available to read on the socket, the message would never be processed, |
| resulting in an OperationTimedOut error. |
| * Don't break tracing when a Session's row_factory is not the default |
| namedtuple_factory. |
| * Handle data that is already utf8-encoded for UTF8Type values |
| * Fix token-aware routing for tokens that fall before the first node token in |
| the ring and tokens that exactly match a node's token |
| * Tolerate null source_elapsed values for Trace events. These may not be |
| set when events complete after the main operation has already completed. |
| |
| Other |
| ----- |
| * Skip sending OPTIONS message on connection creation if compression is |
| disabled or not available and a CQL version has not been explicitly |
| set |
| * Add details about errors and the last queried host to ``OperationTimedOut`` |
| |
| 1.0.0 Final |
| =========== |
| Jan 29, 2014 |
| |
| Bug Fixes |
| --------- |
| * Prevent leak of Scheduler thread (even with proper shutdown) |
| * Correctly handle ignored hosts, which are common with the |
| DCAwareRoundRobinPolicy |
| * Hold strong reference to prepared statement while executing it to avoid |
| garbage collection |
| * Add NullHandler logging handler to the cassandra package to avoid |
| warnings about there being no configured logger |
| * Fix bad handling of nodes that have been removed from the cluster |
| * Properly escape string types within cql collections |
| * Handle setting the same keyspace twice in a row |
| * Avoid race condition during schema agreement checks that could result |
| in schema update queries returning before all nodes had seen the change |
| * Preserve millisecond-level precision in datetimes when performing inserts |
| with simple (non-prepared) statements |
| * Properly defunct connections when libev reports an error by setting |
| errno instead of simply logging the error |
| * Fix endless hanging of some requests when using the libev reactor |
| * Always start a reconnection process when we fail to connect to |
| a newly bootstrapped node |
| * Generators map to CQL lists, not key sequences |
| * Always defunct connections when an internal operation fails |
| * Correctly break from handle_write() if nothing was sent (asyncore |
| reactor only) |
| * Avoid potential double-erroring of callbacks when a connection |
| becomes defunct |
| |
| Features |
| -------- |
| * Add default query timeout to ``Session`` |
| * Add timeout parameter to ``Session.execute()`` |
| * Add ``WhiteListRoundRobinPolicy`` as a load balancing policy option |
| * Support for consistency level ``LOCAL_ONE`` |
| * Make the backoff for fetching traces exponentially increasing and |
| configurable |
| |

| * TravisCI integration for running unit tests against Python 2.6, |
| Python 2.7, and PyPy |
| |
| 1.0.0b7 |
| ======= |
| Nov 12, 2013 |
| |
| This release makes many stability improvements, especially around |
| prepared statements and node failure handling. In particular, |
| several cases where a request would never be completed (and as a |
| result, leave the application hanging) have been resolved. |
| |
| Features |
| -------- |
| * Add `timeout` kwarg to ``ResponseFuture.result()`` |
| * Create connection pools to all hosts in parallel when initializing |
| new Sesssions. |
| |
| Bug Fixes |
| --------- |
| * Properly set exception on ResponseFuture when a query fails |
| against all hosts |
| * Improved cleanup and reconnection efforts when reconnection fails |
| on a node that has recently come up |
| * Use correct consistency level when retrying failed operations |
| against a different host. (An invalid consistency level was being |
| used, causing the retry to fail.) |
| * Better error messages for failed ``Session.prepare()`` opertaions |
| * Prepare new statements against all hosts in parallel (formerly |
| sequential) |
| * Fix failure to save the new current keyspace on connections. (This |
| could cause problems for prepared statements and lead to extra |
| operations to continuously re-set the keyspace.) |
| * Avoid sharing ``LoadBalancingPolicies`` across ``Cluster`` instances. (When |
| a second ``Cluster`` was connected, it effectively mark nodes down for the |
| first ``Cluster``.) |
| * Better handling of failures during the re-preparation sequence for |
| unrecognized prepared statements |
| * Throttle trashing of underutilized connections to avoid trashing newly |
| created connections |
| * Fix race condition which could result in trashed connections being closed |
| before the last operations had completed |
| * Avoid preparing statements on the event loop thread (which could lead to |
| deadlock) |
| * Correctly mark up non-contact point nodes discovered by the control |
| connection. (This lead to prepared statements not being prepared |
| against those hosts, generating extra traffic later when the |
| statements were executed and unrecognized.) |
| * Correctly handle large messages through libev |
| * Add timeout to schema agreement check queries |
| * More complete (and less contended) locking around manipulation of the |
| pending message deque for libev connections |
| |
| Other |
| ----- |
| * Prepare statements in batches of 10. (When many prepared statements |
| are in use, this allows the driver to start utilizing nodes that |
| were restarted more quickly.) |
| * Better debug logging around connection management |
| * Don't retain unreferenced prepared statements in the local cache. |
| (If many different prepared statements were created, this would |
| increase memory usage and greatly increase the amount of time |
| required to begin utilizing a node that was added or marked |
| up.) |
| |
| 1.0.0b6 |
| ======= |
| Oct 22, 2013 |
| |
| Bug Fixes |
| --------- |
| * Use lazy string formatting when logging |
| * Avoid several deadlock scenarios, especially when nodes go down |
| * Avoid trashing newly created connections due to insufficient traffic |
| * Gracefully handle un-handled Exceptions when erroring callbacks |
