添加自定义 Cql3SolrSecondaryIndex 后无法使用 Stargate 进行查询

Question

我的 DEV 服务器中有 stargate 1.0.38 运行。我可以使用 stargate rest api 来获取 auth_token 和运行插入，select 查询。

昨天，我在我的 Cassandra DSE 6.8 中为 table 创建了一个索引 Cql3SolrSecondaryIndex。然后我在 stargate 日志中看到以下错误。在那之后，我删除了那个索引。但即使在删除索引之后，我仍然在星际之门日志中看到以下错误。我也尝试 stop/start 星门，但仍然看到同样的错误。

由于这个错误，我仍然能够得到 auth_token 但所有 select 查询都得到这个错误

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

请帮我解决这个问题。

Answer 1

Stargate 目前不支持搜索和图形等高级工作负载。我认为您可能必须删除并重新创建没有 Solr 索引的键空间才能再次工作，因为模式仍然存在于其他节点上。

此问题已记录在案 here. There has also been a request made to support Solr here。

Answer 2

@David，我能够删除 DSE 搜索索引，执行我的 DSE 节点和 Stargate 节点的滚动重启，它启动得很好，没有任何错误。我确保我之前的所有数据都很好，并且能够使用 Stargate REST、GraphQL 和文档 API 验证运行基本 CRUD 操作，没有任何问题 post 那。
