US Patent 10241893 Streams analysis tool and method

A streams analysis tool allows a user to define one or more buckets according to a specified tuple collection criteria for each bucket. The specified tuple collection criteria for each bucket defines some way to distinguish one data tuple from another. The specified tuple collection criteria for each bucket is therefore used to distinguish data tuples that satisfy the specified tuple collection criteria from data tuples that do not satisfy the specified tuple collection criteria. When a data tuple satisfies the specified tuple collection criteria for a bucket, the data tuple is stored in the bucket. In addition, data tuples preceding or succeeding the data tuple may also be stored in the bucket, as determined by the specified tuple collection criteria. The data tuples in each bucket are analyzed, and based on the analysis a streams manager can change how future data tuples are processed by the streaming application.
