Replication Server 7.0.0 release notes v7
Released: 01 Dec 2021
Note
The 7.0 version is backward compatible with 6.2.x and provides a non-breaking upgrade path for the existing cluster deployments. However, it is strongly recommended to verify it in a staging or nonproduction environment before applying the upgrade in a production environment.
New features, enhancements, bug fixes, and other changes in Replication Server 7.0 include the following:
| Type | Description |
|---|---|
| New feature | The Publication and Subscription Server configuration options can be modified and applied without requiring a server restart. The CLI now exposes a new command reloadconf to reload the updated configuration values at runtime. |
| New feature | Replication Server is enhanced to support replication from EDB Postgres Advanced Server (non-redwood mode) and PostgreSQL to Oracle. |
| Enhancement | Replication Server is certified to support PostgreSQL v14 and EDB Postgres Advanced Server v14. |
| Enhancement | Table-level parallel data loading significantly improves initial Snapshot data replication time for large size Publication tables. The benchmarks reveal 3X to 30X performance improvement for a given workload and related options. |
| Enhancement | Row-level Filtering capability is enhanced to allow inclusion/exclusion of data based on a sub-query [1284035]. |
| Enhancement | The CLI command addtablesintopub is enhanced to expose an option to enable row-level filter for the target Subscription (SMR)/Master (MMR) nodes [1321993]. |
| Enhancement | The CLI commands createpub and addtablesintopub now support a new option to allow the users to add all the tables to a Publication without requiring individual table identification [1273701]. |
| Enhancement | The CLI commands createpub and addtablesintopub are enhanced to allow the user specify a single custom conflict resolution option applicable for multiple tables [731271]. |
| Enhancement | Table(s) can be added into an existing Publication by skipping schema replication [926058]. |
| Enhancement | The Replication GUI displays additional replication stats on the Real-time Monitor tab to monitor the status of the cluster [795247]. |
| Enhancement | Replication of the HASH partition table is now supported from Oracle to EDB Postgres Advanced Server. |
| Enhancement | Incremental replication of CLOB, BLOB, and XMLType is now supported from Oracle to EDB Postgres Advanced Server. |
| Enhancement | Support added for replication of JSON data type from PostgreSQL and EDB Postgres Advanced Server to Oracle. |
| Bug fix | Fixed an issue where replication from EDB Postgres Advanced Server to SQL Server fails for UUID data type [73835]. |
| Bug fix | The CLI reports an error on Publication removal if one or more Subscriptions are associated with the Publication [72194]. |
| Big fix | Fixed an issue where replication history cleanup job fails when Oracle is the active Controller database [72626]. |
| Big fix | Fixed an issue where the filter clause fails when applied for a table list with more than 10 tables. |
| Bug fix | Fixed an issue where the add filter command picked the incorrect table index for the filter clause in the WAL mode replication. |
| Bug fix | In a hybrid replication cluster, the cleanup shadow table routine is subject to remove unprocessed changes. |
| Bug fix | Fixed an issue where synchronize failed for an SMR cluster during replication from PostgreSQL to Oracle 12.1 when using the JSON datatype. |
| Bug fix | Fixed an issue where the initial Snapshot fails in a WAL-based MMR cluster while adding the third database. |
| Bug fix | Fixed an issue where running yum install ppas-xdb skips ppas-xdb-libs dependency. |
| Bug fix | Fixed an issue where the Synchronize operation failed to replicate NULL for a BLOB type for EPAS to Oracle. |
| Bug fix | Fixed an issue where the Synchronize operation fails for one of the target Subscriptions for EPAS to Oracle replication cluster. |
