• The Latin1 character set is supported.

• Connection attributes with special prefixes can be transparently transmitted.

• Distributed transaction routing is supported.

• MySQL binlogs are supported.

• Read/Write splitting and transaction splitting are supported.

• Mappings between VIPs and clusters/tenants can be configured without using MetaDB.

• Global parameters are supported for weak-consistency read and read-only operations.

• The geographic information system (GIS) and JSON data types are supported.

• IPv6 is supported.

• Accurate routing is supported for access to the sys tenant in QA mode.

• ROWID routing is supported in PS mode.

• Multi-partitioning key routing is supported.

• Routing is supported in obtaining the default values of columns.

• Expression-based calculation is supported for nvl, sysdate, mod, to_char, and substr.

• Routing is supported for IS NULL and IS NOT NULL.

Feature updates

• The recovery time objective (RTO) is reduced to a value less than 8s.

• The OceanBase 2.0 protocol is optimized to reduce the statements for synchronization.

• An error packet will be sent to the client if ODP actively disconnects from the client.

• Global-level PS cache is supported.

• The default value of client_sock_option_flag_out is changed from 2 to 3.

• Trace IDs of OBServer nodes will be recorded in the obproxy_error.log file.

• The connection memory and PS memory are optimized.

• The RTO in keepalive detection is optimized. ODP considers that the client is normal if it receives a handshake packet from the client.

• The default character set for handshake packets is changed to 46.

• The enable_binlog_service parameter is added for enabling or disabling the binlog service. The default value is False.

Bug fixes

• Fixed the issue that a core dump occurs when you access a partitioned table by carrying the row ID.

• Fixed the issue where no information is returned after a prepared statement is deleted when the OceanBase 2.0 protocol is enabled between the client and ODP.

• Fixed the issue where the error "requestId mismatch" is returned if an SQL statement is executed after a PREPARE statement is executed in the case of an exception, when the OceanBase 2.0 protocol is enabled between the client and ODP.

• Fixed the issue that the client is hung because the error packet returned for an internal SQL statement is in an incorrect format.

• Fixed the issue where disconnection occurs if the error 4016 is returned when the OceanBase 2.0 protocol is enabled.

• Fixed the issue where disconnection occurs during SQL rerouting when enable_ob_protocol_v2_with_client is set to True.

• Fixed the issue that ODP is disconnected due to connection ID mismatch.

• Fixed the issue that disconnection occurs after the compression protocol is enabled.

• Fixed the issue that if the username in the COM_CAHNGE_USER command is not in the user_name@tenant_name format, the command cannot be used.

• Fixed the issue of inaccurate routing for the DATE type in some scenarios.

• Fixed the issue of core dump caused by the abnormal to_timestamp parameter.

• Fixed the issue where a core dump occurs when an anonymous block is executed in OceanBase Developer Center (ODC).

• Fixed the issue of remote routing for the to_date() function.

• Fixed the issue of inaccurate routing for LIST partitions of the timestamp with local time zone type.

• Fixed the issue where a core dump occurs if no pointer is specified for some keywords.

• Fixed the issue where an OBServer node cannot be removed from the blocklist after being added to the blocklist by the detection optimization feature.

• Fixed the issue of SSL configuration acquisition failure.

• Fixed the issue that the cluster cannot be connected after CPU resource isolation is enabled in the public cloud.

• Fixed the issue where the vid configuration that uses the INT form does not take effect.

• Fixed the issue that the subscript of the substr() function is out of range.

• Fixed the issue that calculation errors occur for RANGE partitions under the condition where c1 >20.

• Fixed the issue where routing fails due to a type conversion failure that occurs when a LIST- or LIST COLUMNS-partitioned table contains NULL values.

• Fixed the issue of core dump caused by global PS.

• Fixed the issue where the autocommit value in the OK packet is still 1 after the SET autocommit=0 command is executed.

• Fixed the issue where disconnection occurs when some fields of RespResult are not initialized in constructor functions.

• Fixed the issue of supported complex parameter types in XA_START hold & sync after the PreparedStatement and PrepareExecute protocols are enabled.

• Fixed the issue that multiple OceanBase 2.0 packets are not accepted during XA_START hold & sync.
