在 OceanBase 数据库中，创建索引是一个多阶段的过程。了解索引创建的不同阶段以及如何观察每个阶段的进度对于数据库管理和性能优化至关重要。本文介绍如何观察 OceanBase 数据库创建索引的进度。
索引创建的阶段
OceanBase 数据库创建索引的过程主要可以分为以下几个阶段：
准备阶段：生成索引表的元数据信息，索引表设置为只写状态；等待之前未向索引表插入数据的事务结束，获取构建快照点。
构建阶段：基于获取的快照点扫描主表数据，并将数据写入索引表基线 SSTable 中，同时将增量事务产生的数据写入到 MemTable 中，并完成基线补全，即将快照点后的 DML 操作同步到索引中。
拷贝阶段：索引构建在单副本上完成后，会通过一致性算法将数据同步到索引表的多个副本中。
收尾阶段：进行数据校验，对于唯一索引还需要进行唯一性校验。完成后索引表设置成可读写状态，否则设置为不可用状态。
观察全局索引创建过程
全局索引主要依靠观察 __all_index_build_stat 信息表定位创建到哪个阶段。
该表的 status 列值对应如下：
0 = invalid，创建本地索引时观察该值为 0 1 = 单副本构建 2 = 多副本拷贝 3 = 校验唯一性 4 = 校验和比对 5 = 设置索引生效 6 = 构建索引失败 7 = 构建索引完成
以下示例基于 OceanBase 数据库 V2.2.77 版本，MySQL 租户。
准备阶段。
a. 查看建表语句。

观察本地索引创建过程
本地索引创建过程不能依靠 __all_index_build_stat 信息表定位创建到哪个阶段。
以下示例基于 OceanBase 数据库 V2.2.77 版本，MySQL 租户。
准备阶段。
a. 模拟未提交事务。
mysql> begin;replace into t1 select * from t1 limit 1; Query OK, 0 rows affected (0.01 sec)b. 执行建索引语句。
mysql> create index idx_pad on t1(pad) local;c. 观察信息表，__all_index_build_stat 的 status 为 0，__all_index_wait_transaction_status 为空。
mysql> select * from __all_index_build_stat;输出结果如下：

mysql> select * from __all_index_wait_transaction_status where gmt_create>'2022-04-05 23:47:00' and tenant_id=1014; Empty set (0.01 sec)e. rollback 事务后，继续观察信息表，__all_index_wait_transaction_status 出现 partition_id 为 -1 的记录。
mysql> select * from __all_index_wait_transaction_status where gmt_create>'2022-04-05 23:47:00' and tenant_id=1014;输出结果如下：

mysql> select * from __all_virtual_rebalance_task_stat; Empty set (0.00 sec)综上__all_virtual_table_mgr 副本已全部补齐，__all_virtual_long_ops_status进度全部为100
补充：查询 select index_status from __all_virtual_table where table_id= 索引表 id，为 2 说明索引表构建成功。
观察历史任务表，可供参考。

总结
诊断任务与事件状态的内部虚拟表。
通过查询内部虚拟表，如 __all_index_build_stat、__all_index_wait_transaction_status、__all_virtual_sys_task_status 等，可以实时监控索引构建的进度和状态。
检查展示正在执行的任务和记录当前正在进行的负载均衡任务的常用的任务与事件诊断用的虚拟表和视图，如 __all_virtual_sys_task_status 和__all_virtual_rebalance_task_stat，以获取相关分区的索引创建任务和分布式任务信息。
通过 __all_virtual_table_mgr 表，可以观察到 MemTable 的创建和 SSTable 的拷贝情况。
历史事件记录表。
- 通过查询历史事件记录表 __all_rootservice_event_history 和__all_server_event_history 内部虚拟表获取的详细信息，包括快照、任务开始/完成、SSTable 复制等事件的记录。
注意
观察索引创建进度是一个动态的过程，需要定期查询系统表以获取最新的状态信息。索引创建的时间取决于多种因素，如表的大小、系统的负载、副本的数量等，当创建索引可能会影响数据库的性能，建议在低峰时间段进行。
适用版本
OceanBase 数据库 V2.x 和 V3.x 版本。
