努力了一个多月吧算是，成绩算不上多好。最后决赛第二十，勉强进入答辩。

怀抱着半吊子的心态也只能得到半吊子的成绩，也是活该。

对自己预期过高了，觉得稍微搞搞就能获得还好的排名，但是过于低估oceanbase赛的竞争激烈程度了。

如果一开始就准备一番苦战，中期明确好优化方案的话，多读几篇HNSW相关的论文，写完回表优化，写完in-filter优化的话，也许还能竞争一下三等奖。

总结：真的一个充满妥协的一次比赛。

好消息是以后再也不用参加oceanbase赛了。

坏消息是以后再也不能参加oceanbase赛了。

今年也算是把数据库相关的比赛给参加一遍了，以后可能就很少参加比赛了。

具体代码在faiss分支。

OceanBase Database is a distributed relational database. It is developed entirely by Ant Group. The OceanBase Database is built on a common server cluster. Based on the Paxos protocol and its distributed structure, the OceanBase Database provides high availability and linear scalability. The OceanBase Database is not dependent on specific hardware architectures.

Key features

• Transparent Scalability: 1,500 nodes, PB data and a trillion rows of records in one cluster.
• Ultra-fast Performance: TPC-C 707 million tmpC and TPC-H 15.26 million QphH @30000GB.
• Cost Efficiency: saves 70%–90% of storage costs.
• Real-time Analytics: supports HTAP without additional cost.
• Continuous Availability: RPO = 0(zero data loss) and RTO < 8s(recovery time)
• MySQL Compatible: easily migrated from MySQL database.

Quick start

See also Quick experience or Quick Start (Simplified Chinese) for more details.

🔥 Start with all-in-one

You can quickly deploy a stand-alone OceanBase Database to experience with the following commands:

Note: Linux Only

# download and install all-in-one package (internet connection is required)
bash -c "$(curl -s https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/oceanbase-all-in-one/installer.sh)"
source ~/.oceanbase-all-in-one/bin/env.sh

# quickly deploy OceanBase database
obd demo

🐳 Start with docker

Note: We provide images on dockerhub, quay.io and ghcr.io. If you have problems pulling images from dockerhub, please try the other two registries.

1. Start an OceanBase Database instance:

   # Deploy a mini standalone instance.
   docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d oceanbase/oceanbase-ce
   
   # Deploy a mini standalone instance using image from quay.io.
   # docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d quay.io/oceanbase/oceanbase-ce
   
   # Deploy a mini standalone instance using image from ghcr.io.
   # docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d ghcr.io/oceanbase/oceanbase-ce

2. Connect to the OceanBase Database instance:

   docker exec -it oceanbase-ce obclient -h127.0.0.1 -P2881 -uroot # Connect to the root user of the sys tenant.
