我的 DEV 服务器上运行良好的 stargate 1.0.38。我可以使用 stargate rest api 来获取 auth_token 并运行插入、选择查询。

昨天，我在 Cassandra DSE 6.8 中为表创建了索引 Cql3SolrSecondaryIndex。然后我在星门日志中看到以下错误。之后，我删除了该索引。但即使删除索引后，我仍然在星门日志中看到以下错误。我也尝试停止/启动星际之门，但仍然看到相同的错误。

由于这个错误，我仍然能够得到 auth_token 但所有的选择查询都会得到这个错误

{
    "description": "Resource not found: keyspace 'test' not found",
    "code": 404
}

请帮我解决这个问题。

Stargate 目前不支持搜索和图形等高级工作负载。我认为您可能必须在没有 Solr 索引的情况下删除并重新创建该键空间才能使其再次工作，因为该模式仍然存在于其他节点上。

此问题已在此处记录。这里也有支持 Solr 的请求。

@David，我能够删除 DSE 搜索索引，对我的 DSE 节点和 Stargate 节点执行滚动重启，它启动得很好，没有任何错误。我确保我之前的所有数据都正常存在，并且能够使用 Stargate REST、GraphQL 和文档 API 验证运行基本 CRUD 操作，而不会出现任何问题。
