+==== {dataframes-cap}: transform and pivot your streaming data
+
+beta[] {stack-ov}/ml-dataframes.html[{dataframe-transforms-cap}] are a core new
+feature in {es} that enable you to transform an existing index to a secondary,
+summarized index. {dataframe-transforms-cap} enable you to pivot your data and
+create entity-centric indices that can summarize the behavior of an entity. This
+organizes the data into an analysis-friendly format.
+
+{dataframe-transforms-cap} were originally available in 7.2. With 7.3 they can
+now run either as a single batch transform or continuously incorporating new
+data as it is ingested. 
+
+{dataframes-cap} enable new possibilities for {ml} analysis (such as
+_outlier detection_), but they can also be useful for other types of
+visualizations and custom types of analysis.
