Question

我正在使用PrestoSQL（334/338）从托管 MongoDB（Atlas）中读取数据。

Presto成功连接到Mongo目录，但是每个查询（针对各种方案，表，集合）均失败，并显示错误

Query 20200719_060423_00001_xcbmw failed: org.bson.BsonInvalidOperationException: Document does not contain key clusterTime

（我的收藏集中都没有定义 clusterTime 字段）

以下是我的mongodb目录文件：

connector.name=mongodb
mongodb.seeds=XXX-shard-00-00-6owtm.gcp.mongodb.net:27017,XXX-shard-00-01-6owtm.gcp.mongodb.net:27017,XXX-shard-00-02-6owtm.gcp.mongodb.net:27017
mongodb.credentials=xxx:xxx@reader
mongodb.ssl.enabled=true
mongodb.write-concern=MAJORITY
mongodb.required-replica-set=XXX-shard-0

完整堆栈跟踪：

此问题已在PrestoSQL 339

上修复。

Presto为每个MongoDB查询抛出“文档不包含键clusterTime”
