全量表与直写表的数据更新问题

1. 对于全量表，看文档首次create后用swift写新数据，假如增量数据较多想重新用bs完整构建索引，然后应该用什么命令才能更新这个新的全量索引？还是说只能删除旧表然后新建一张表？或者是像ES一样有别名机制可以无缝切换不影响线上查询？
2. 对于直写表，用sql insert写入数据，是否还支持update / delete等sql？
3. 全量表与直写表线上查询时性能是否有差异？

Start with Havenask's documentation for full-build tables, direct-write tables, indexing, and SQL operations. Trace the documented commands and supported table operations, then compare the query-performance guidance for both table types. Done means updating the documentation with clear answers to all three questions, including any limitations or replacement workflow.
