# Data Transfer release notes

## 2026 {#2026}

### May {#may26}

#### New features and improvements {#new-features-may26}

* Added support for a new [Apache Iceberg™ target endpoint](../operations/endpoint/target/iceberg.md).

* In ![greenplum](../../_assets/data-transfer/icons/greenplum-icon.svg) Greenplum® endpoints, added support for [Apache Cloudberry™](https://cloudberry.apache.org/).

### April {#apr26}

#### New features and improvements {#new-features-apr26}

* Added support for transfer of non-table [Greenplum®](../operations/endpoint/source/greenplum.md) objects (functions, sequences, indexes).

* Added support for compression at the data format level for Parquet when writing to an [Object Storage](../operations/endpoint/target/object-storage.md) target.


* Added support for writing from [Data Streams](../operations/endpoint/source/data-streams.md) to [OpenSearch](../operations/endpoint/target/opensearch.md).


### March {#mar26}

#### New features and improvements {#new-features-mar26}

* Supported the nginx data format for the [Object Storage](../operations/endpoint/source/object-storage.md) data source.

* Revised the name format for objects created in a [Object Storage](../operations/endpoint/target/object-storage.md) target: part-<timestamp>-<hash(partID)>.<counter>.<file_type>.

  * <timestamp>: `timestamp` by operation ID.
  * <hash(partID)>: `UUID` generated based on `partID`.
  * <counter>: Incrementing counter.
  * <file_type>: File extension (`csv`, `parquet`, `json`, `proto`, or `nginx`).

* For **Snapshot** transfers from [PostgreSQL sources](../operations/endpoint/source/postgresql.md), supported permanent data reads from a parent table provided it is included in the endpoint or transfer table list.

* For YDB, Apache Kafka®, and YDS sources, supported a new data conversion type, `Raw-to-table`, which allows delivering raw data from a message queue.


### February {#feb26}

#### New features {#new-features-feb26}

* Significantly improved the speed of [PostgreSQL](../operations/endpoint/source/postgresql.md)-to-[PostgreSQL](../operations/endpoint/target/postgresql.md) data transfers.
* Improved database schema migration for [PostgreSQL](../operations/endpoint/source/postgresql.md)-to-[PostgreSQL](../operations/endpoint/target/postgresql.md) transfers. Entities are now migrated sequentially based on dependencies between them.


* Number of VMs allocated for the copy stage will be limited to 64.


#### Fixed issues {#problems-solved-feb26}

* Improved transfer stability for [Apache Kafka® sources](../operations/endpoint/source/kafka.md).
* Fixed sending metric to Monitoring from the [Oracle source](../operations/endpoint/source/oracle.md).
* Fixed the issue with [PostgreSQL](../operations/endpoint/source/postgresql.md)-to-[PostgreSQL](../operations/endpoint/target/postgresql.md) data transfers, where defining the table list at the transfer level (rather than the endpoint) caused the transfer of the entire schema.
* Fixed an issue where simultaneous updates to endpoint and transfer settings via the API and Terraform triggered multiple transfer restarts.
* Fixed the table vacuuming issue for the [Managed Service for YDB target](../operations/endpoint/target/yandex-database.md).
* Fixed freezes and duplicate delivery of large data volumes during replications from [Managed Service for YDB](../operations/endpoint/source/ydb.md).
* Fixed an issue where deletions failed to propagate to ClickHouse® if columns contained certain types, e.g., UUID.



### January {#jan26}

 You can now configure [Apache Kafka® connections](../operations/endpoint/source/kafka.md) and [Data Streams](../operations/endpoint/source/data-streams.md) in the [Schema Registry](../../metadata-hub/concepts/schema-registry.md) data source settings.
