Today, we announced @dataArtisans Streaming Ledger: Serializable ACID transactions across multiple tables, keys, and streams, in pure stream processing. We are removing the long standing limitation that streaming applications can only operate consistently on one key at a time. Many applications need to guarantee integrity of data, with constraints across many tables, rows, entries, or keys. Examples are plentiful anywhere you deal with financial data, in master data management, in logistics, etc.
All these applications now become streamable.
