  • Java editions now bundle: kafka-clients 3.6.1, lz4-java 1.8.0, slf4j-api 1.7.36, snappy-java 1.1.10.5, zstd-jni 1.5.5-1, Jackson 2.13.5 (jackson-annotations, jackson-core, jackson-databind, jackson-datatype-jdk8), jose4j 0.9.3, org.osgi.core 6.0.0
11/29/20238733GeneralChanged
  • The ROUND function doesn't accept the negative precision values anymore.

Changed
  • The returning types of the FDMonth, FDQuarter, FDWeek, LDMonth, LDQuarter, LDWeek functions are changed from Timestamp to Date.
  • The return type of the ABS function will be consistent with the parameter value type.
11/13/20238717Apache KafkaChanged
  • Java editions now bundle: kafka-clients 3.6.0, lz4-java 1.8.0, slf4j-api 1.7.36, snappy-java 1.1.10.4, zstd-jni 1.5.5-1, Jackson 2.13.5 (jackson-annotations, jackson-core, jackson-databind, jackson-datatype-jdk8), jose4j 0.9.3, org.osgi.core 6.0.0
  • .NET editions now reference Confluent.Kafka 2.3.0 and its dependencies (check its NuGet page for a complete list)
10/27/20238700jdbcChanged
  • Added support for Connection.abort() method.
08/22/20238634Apache KafkaAdded
  • Added support for authenticating to Azure Event Hubs with OAuth. AzureAD, AzureServicePrincipal, AzureServicePrincipalCert, and AzureMSI are all supported.
08/03/20238615Apache KafkaChanged
  • ProduceMessage now uses MessageText/MessageBytes to provide the message body, with corresponding inputs for the key.

Removed
  • ProduceMessage no longer accepts input streams for providing raw keys and messages.
06/20/20238571GeneralAdded
  • Added the new sys_lastresultinfo system table.
04/25/20238515GeneralRemoved
  • Removed support for the SELECT INTO CSV statement. The core code doesn't support it anymore.
04/19/20238509Apache KafkaAdded
  • Added ProduceMessage stored procedure for producing messages. It can be used to publish raw messages to topics regardless of the connection TypeDetectionScheme.
  • Added support for binary message keys by setting MessageKeyType=binary.
03/14/20238473Apache KafkaAdded
  • Added support for reading and writing specific partitions. A SELECT that filters on a specific value (or set of values) from the Partition column will subscribe to just those partitions. This increases read performance when many partitions are present. An INSERT can provide a value for the Partition column to write a message to a partition instead of having it auto-assigned.
12/14/20228383GeneralChanged
  • Added the Default column to the sys_procedureparameters table.
11/22/20228361Apache KafkaAdded
  • Added support for detecting the correct serialization format when performing an INSERT. The driver will determine this from either the schema registry or by row scan, depending upon the TypeDetectionScheme propery. This allows connections with SerializationFormat=AUTO to insert data when the serialization format is unknown or different across topics. Other values of SerializationFormat keep their old behavior and skip this format detection.
10/26/20228334Apache KafkaChanged
  • Updated the versions of the Kafka libraries used in both Java and .NET. JDBC now bundles kafka-clients 3.3.1 while ADO.NET is built against Confluent.Kafka 1.9.3. The new version of Confluent.Kafka only supports .NET Framework versions 4.6.2 and up. The supported versions for other .NET variants (.NET Standard and .NET 5+) are unaffected.
09/30/20228308GeneralChanged
  • Added the IsPath column to the sys_procedureparameters table.
08/05/20228252Apache KafkaAdded
  • Added support for CreateTablePartitions and CreateTableReplicationFactor. This allows CREATE TABLE to be used on smaller clusters, and to be tuned for better read throughput or higher failover redundancy.
07/18/20228234Apache KafkaAdded
  • Added support for ConsumerProperties and ProducerProperties options. These allow for direct configuration of the underlying Kafka client libraries, in cases where the driver doesn't expose its own version of a property.
06/11/20228197jdbcChanged
  • The method GetJDBCMinorVersion() and GetJDBCMajorVersion() return 4.2 as the supported JDBC major / minor version.
05/03/20228158Apache KafkaAdded
  • RegistryClientCert and related properties, as well as RegistryServerCert. These properties are used for the schema registry specifically and support the same SSL options as other providers. They are added to avoid confusion between what SSL properties apply to the schema registry vs. the Kafka broker.

Deprecated
  • The SSLKey, SSLCert and SSLCertPassword properties as well as TrustStorePassword and TrustStorePath. These hidden properties were required to connect to brokers via SSL, but they were specific to each edition and did not expose all of the certificate formats that the Kafka client libraries could accept.

Replacements
  • SSLClientCert and related properties, as well as SSLServerCert and related properties. Internally these configure the same Kafka client properties, but the names and values of these options more consistent with the registry SSL options. Only a subset of certificate types are supported due to limitations of the Kafka client libraries.
04/28/20228153jdbcChanged
  • Removed support for JRE 1.6. JRE 1.8 and above is now required.
04/20/20228145Apache KafkaAdded
  • Added support for Confluent-compatible Avro encoding with the UseConfluentAvroFormat option. The default format is still the Avro file block format, but setting this option allows the provider to produce messages which can be read and validated by Confluent tools and libraries.
04/07/20228132Apache KafkaChanged
  • Updated the versions of the Kafka libraries used in both Java and .NET. .NET now requires the following assemblies to be present at runtime: Confluent.Kafka (and librdkafka.redist) : 1.8.2.0 System.Memory: 4.5.2 System.Buffers: 4.5.1 System.Runtime.CompilerServices.Unsafe: 4.5.3
03/30/20228124Apache KafkaAdded
  • Added support for authenticating using SCRAM-SHA-512.
02/25/20228091jdbcChanged
  • The method DatabaseMetaData.getTypeInfo() now returns all of the data types that the driver supports. Previously, it was returning only a portion of the data types. The types include: tinyint, smallint, int, bigint, float, double, numeric, decimal, bit, date, datetime, time, varchar, binary, uuid.
02/24/20228090jdbcChanged
  • Corrected the return value of method DatabaseMetaData.supportsOuterJoins(), which used to return an incorrect value.
12/13/20218017Apache KafkaRemoved
  • Removed unnecesary dependencies relating to embedded Kafka servers. This also removes the log4j component which was affected by the recent CVE reports.
10/27/20217970jdbcChanged
  • Added support for JDK 17
09/23/20217936Apache KafkaAdded
  • Added support for Authenticating with Kerberos on both JDBC and ADO editions.
09/12/20217925jdbcRemoved
  • Removed the IS_READONLY, IS_KEY, NUMERIC_PRECISION, and DECIMAL_DIGITS columns from DatabaseMetadata.GetColumns(), as they are not part of the JDBC Specification. This information is still available via other metadata calls.
09/02/20217915GeneralAdded
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
08/26/20217908Apache KafkaAdded
  • Added support for AWS Glue Schema Registry service. Now we support Confluent and AWS Glue Schema Registry types.
08/07/20217889GeneralChanged
  • Added the KeySeq column to the sys_foreignkeys table.
08/06/20217888GeneralChanged
  • Added the new sys_primarykeys system table.
07/23/20217874GeneralChanged
  • Updated the Literal Function Names for relative date/datetime functions. Previously, relative date/datetime functions resolved to a different value when used in the projection as opposed to the predicate. For example: SELECT LAST_MONTH() AS lm, Col FROM Table WHERE Col > LAST_MONTH(). Formerly, the two LAST_MONTH() methods would resolve to different datetimes. Now, they will match.
  • As a replacement for the previous behavior, the relative date/datetime functions in the criteria may have an 'L' appended to them. For example: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that were previously calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
07/12/20217863Apache KafkaRemoved
  • Removed the Topic static table. Previously it was used only to retrieve some static columns. Now it's no longer needed.
06/23/20217844Apache KafkaAdded
  • Added support for JSON Scheme type on SchemaRegistry mode. Now we support AVRO and JSON schema types.
04/23/20217783GeneralChanged
  • Updated how display sizes are determined for varchar primary key and foreign key columns so they will match the reported length of the column.
04/16/20217776GeneralChanged
  • Reduced the length to 255 for varchar primary key and foreign key columns.

Changed
  • Updated index naming convention to avoid duplicates.
04/16/20217776GeneralChanged
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you need to generate new metadata caches if you are currently using CacheMetadata.
