                                            Ignite scales up and out across memory and disk. By default, Ignite operates
                                            in a pure in-memory mode. But, by toggling a single configuration setting,
                                            you can turn a cluster into a database that can grow beyond
                                            the cluster's memory capacity:

                                            Ignite machine learning uses built-in algorithms and tools, as well as
                                            TensorFlow integration, to enable the building of scalable machine learning

                                            your ML and DL models continuously and at scale:

                                            the database and application side:

                        Accelerate your existing applications by 100x using Ignite as an in-memory cache or in-memory
                        data grid that is deployed over one or more external databases. Think of a cache that you can
                        query with SQL, transact, and compute on.

                    <p>
                        Build modern applications that support transactional and analytical workloads by using Ignite as
                        a database that scales beyond the available memory capacity. Ignite allocates memory for your hot
                        data and goes to disk whenever applications query cold records.
