Abstract: In an embodiment, a method comprises receiving, at an analytics engine, from a separate analytics application, an analytics query for data that is potentially available in data streams of networked computing devices; sending, to a distributed network analytics controller, sub-queries based on the analytics query; determining distributed network analytics agents capable of executing each of the sub-queries; sending instructions to the agents to initiate the sub-queries for the data at specified locations; initiating execution of the sub-queries on data streams that are locally available at one of the networked computing devices at which the agents are running; forming summarized data streams and zero or more raw data streams at the networked computing devices having the analytics agents; sending the summarized data streams and the zero or more raw data streams to the analytics engine; wherein the method is performed by computing device(s).

Abstract: In an embodiment, a method comprises receiving a plurality of source data records from one or more source computers, wherein one or more first source data records are associated with a first source transaction and one or more second source data records are associated with a second source transaction; generating a first derived transaction comprising one or more first derived records based on the plurality of source data records; generating a first transaction mapping between the first derived transaction and the first source transaction; generating a second transaction mapping between the first derived transaction and the second source transaction; determining that the first derived transaction has ended, and in response, committing first derived transaction including the one or more first derived records to a persistent storage; receiving a first ending punctuation associated with the first source transaction, and in response, committing the first source transaction including the one or more first source data records associated with the first source transaction to the persistent storage; after committing the first derived transaction, determining that the second source transaction failed, and in response: determining that the first derived transaction should be regenerated based on the second transaction mapping, and in response, regenerating the first derived transaction.

Abstract translation: 在一个实施例中，一种方法包括从一个或多个源计算机接收多个源数据记录，其中一个或多个第一源数据记录与第一源事务相关联，并且一个或多个第二源数据记录与第二源 交易; 基于所述多个源数据记录，生成包括一个或多个第一导出记录的第一导出事务; 在所述第一派生事务和所述第一源事务之间生成第一事务映射; 在所述第一派生事务和所述第二源事务之间生成第二事务映射; 确定第一派生交易已经结束，并且作为响应，将包括一个或多个第一派生记录的第一派生交易提交给持久存储器; 接收与所述第一源事务相关联的第一结束标点符号，并且作为响应，将包括与所述第一源事务相关联的所述一个或多个第一源数据记录的所述第一源事务提交给所述持久存储器; 在提交第一派生事务之后，确定第二源事务失败，并作为响应：确定基于第二事务映射来重新生成第一派生事务，并作为响应，重新生成第一派生事务。
