| Availability | The documentation says OceanBase supports high availability and disaster recovery at node, data center, and region levels. | TiCDC has no single point of failure and supports dynamically adding and deleting TiCDC nodes. |
| Company founding | OceanBase states that its database operation began in 2010. | LinkedIn states that the TiDB organization was founded in 2015 by three software engineers. |
| Deployment | OceanBase Community Edition is open source, OceanBase Enterprise is self-hosted, and OceanBase Cloud is fully managed across cloud providers. | TiCDC can be deployed with a new TiDB cluster or added to an existing cluster using TiUP. |
| Documentation | Official documentation covers deployment, migration, MySQL and Oracle compatibility, application development, drivers, ORMs, security, backup, monitoring and troubleshooting. | The TiCDC documentation includes deployment, changefeeds, monitoring, alerting, troubleshooting, performance tuning, integration scenarios, APIs, compatibility, FAQs, and a glossary. |
| Founded | 2010 | 2015 |
| High availability | OceanBase documents multi-replica availability and disaster recovery from node level through five data centers across three regions. | TiCDC has no single point of failure and supports dynamically adding or deleting TiCDC nodes. |
| Purpose | OceanBase Database is a distributed database for transactional, analytical, and AI workloads. | TiCDC replicates incremental data from TiDB by capturing TiKV change logs, sorting the changes, and exporting row-based data to downstream systems. |
| Security | The Trust Center lists role and permission management, network whitelists, encrypted communication, transparent data encryption, and SQL auditing. | The deployment guide documents enabling TLS between TiDB components, including TiCDC. |
| Support | The Trust Center describes an L1–L2–L3 after-sales service system providing 24/7 service. | PingCAP directs paid-plan users to support tickets and all users to community Slack support. |
| System requirements | Production guidance calls for at least three servers, four CPU cores and 16 GB RAM per server, with SSD storage, at least 20 GB disk and gigabit networking. | Production guidance recommends at least 16 CPU cores, 64 GB memory, a 500 GB SSD, a 10-Gigabit network card, and two TiCDC instances. |
| What it does | OceanBase is a distributed relational database designed for transactional, analytical and AI workloads. | TiCDC captures TiKV change logs, orders them, and exports row-level incremental changes from TiDB to downstream systems. |

In their own words
OceanBase Database
OceanBase Database is a distributed database for transactional, analytical, and AI workloads in one system. Built-in compatibility with Oracle and MySQL is intended to simplify migration. Deployment choices include the open-source Community Edition, self-hosted Enterprise, and fully managed OceanBase Cloud across cloud providers. Documentation describes high availability and disaster recovery at node, data-center, and region levels. Linux installation packages are listed for Alibaba Cloud Linux, CentOS, Red Hat, Ubuntu, Debian, and Anolis OS. Docker deployment can be used on Windows and macOS, though the documentation cautions that this method has not been validated at scale. A standalone instance can be used for learning; production environments require at least three servers. Community Edition is free and includes full kernel capabilities. Enterprise pricing is available on request. Security features include role and permission management, network whitelists, encrypted communication, transparent data encryption, and SQL auditing, but Community Edition does not support security audit.
TiCDC
TiCDC is a free, open-source, self-hosted tool for replicating incremental data changes from TiDB. It captures TiKV change logs, sorts the changes, and exports row-based data to systems including TiDB, MySQL-compatible databases, Kafka, Amazon S3, GCS, Azure Blob Storage, and NFS. Recommended Kafka formats include Canal-JSON, Avro, and Debezium. Filters can select databases, tables, DMLs, and DDLs, while the Open API can check task status, change task configuration, and create or delete tasks. TiCDC supports replication between TiDB clusters for disaster recovery, with second-level RPO and minute-level RTO, as well as bidirectional replication for multi-active deployments. It can be deployed with a new cluster or added to an existing one; production guidance recommends at least two instances. The system has no single point of failure and allows nodes to be added or removed dynamically. Delivery is at least once, so failures can lead to repeated statements or Kafka messages.
