New features

Automatic storage scale-out

You can configure rules for automatic storage scale-out and specify the upper limit for automatic scale-out. After the automatic storage scale-out feature is enabled, when the storage space of a cluster is about to be exhausted, the storage space can be automatically scaled out to ensure the stability of online business. This feature applies to scenarios with a large business data volume or frequent and drastic fluctuations in the business volume.

Automatic storage scale-out

Access address optimization

You can add two access addresses for the multi-IDC deployment solution. If you want to add two access addresses, they must be read-only addresses. If you want to add only one access address, it can be a read-only or read/write address.

Add an access address

Change of the minimum tenant specifications

In OceanBase Database V3.x and later, the minimum specifications for tenants in a cluster instance are changed from 2C5G (2 CPU cores and 5 GB of memory) to 1C4G (1 CPU core and 4 GB of memory). This way, a cluster can support more tenants with the same resources, thereby reducing the costs.

Create a tenant

Backup and restore enhancement

  • Restore based on backup sets is supported. You can perform restore based on an existing backup set at a specific point in time.

  • Remote archive backup is supported. If long-term retention of backup files is required, you can store backup files locally or remotely to implement geo-disaster recovery. Remote archive backup files are retained for 60 to 7,200 days. In other words, archive backup files are stored for at least 60 days. Those stored for less than 60 days are charged by 60 days.

Standard edition (key-value)

Key-value is the NoSQL model of OceanBase Database that bypasses the SQL engine and directly reads data from the storage engine. The key-value model of OceanBase Database takes full advantage of a new database architecture that integrates both NoSQL and SQL features and provides a variety of non-relational APIs that are simpler and more efficient to meet your requirements in different scenarios. At present, the key-value model supports only specifications of 32 and 64 CPU cores.

ODC user guide

ODC supports static data desensitization and allows you to enable data desensitization strategies in operations such as data export and result set export.

For example, ODC supports built-in desensitization rules for data such as email addresses, bank card numbers, phone numbers, ID card numbers, and names. You can configure desensitization strategies based on the valid range of database name.table name.field name specified by the desensitization rules.

ODC also allows you to configure custom desensitization rules by using desensitization algorithms such as masking, character replacement, format retaining, hashing, rounding, and null value assignment.

Data desensitization management

The shadow table synchronization feature is added, which automatically creates shadow table schemas in the same database based on the schemas of source tables and automatically synchronizes the schemas to the destination.

Synchronization of shadow tables

Shadow table synchronization tasks

The partitioning plan feature is added, which supports automatic precreation and deletion of expired RANGE partitions and RANGE COLUMNS partitions.

Partitioning plans

Partitioning plan task

SQL plan tasks are supported. ODC can periodically execute SQL scripts created by users to complete database development and O&M tasks as required by the users.

SQL plans

SQL plan task

Automatic authorization rules are added. The administrator of the public resource console can automatically assign specific roles or permissions to users that meet specified conditions when they log on to the console for the first time or when they are created, which avoids redundant authorization. For example, the administrator can authorize users whose name, organization, department, or logon method meets specified judgment conditions.

Automatic authorization rules

SQL window optimization:

  • Before you execute an SQL statement, you can specify whether to enable Obtain Column Information of Result Set. If the table contains a large number of columns, we recommend that you disable this option. After you disable this option, column comments and editable columns are not queried, which shortens the SQL execution time.

  • The maximum size of a CLOB field in the result set is changed to 2 MB for texts, 200 KB for hexadecimals, and 20 MB for images.

  • When you edit a result set, you can export specified rows to the clipboard.

  • You can view the information of a field, such as its type and remarks, in the status bar of the result set.

  • SQL specification check is supported when you edit SQL statements in the SQL window, create database change tasks, or create tables.

SQL window

Import and export:

  • When you import a single CSV table, you can skip the first row.

  • You can merge DDL statements into one SQL file and sort them by foreign keys when you export only the schema.

  • When you export data, you can set the maximum size of a single file. The size can be 64 MB, 512 MB, 1,024 MB, 2,048 MB, or not limited.

  • You must call the TO_DATE or TO_TIMESTAMP function to export SQL statements of date and time data types.

Backup and restore

Remote backup files of a cluster can be used to restore the cluster to the region where the remote backup files are located. In other words, assuming that the remote backup files of cluster A are stored in the region in which cluster B is located, tenants of cluster A can be restored to cluster B by using the remote backup files of cluster A. In this case, the restore is initiated from cluster B, namely the destination cluster.

Logical backup supports incremental data backup, which ensures data consistency for tables without downtime.
