As of October 23, 2020, Apache Ignite 2.9 is available. Like every other Ignite release, release 2.9 includes many changes. Let's take a look at the major features of release 2.9.

Cluster Snapshots

Ignite 2.9 provides the ability to create full cluster snapshots for deployments that use Ignite Persistence. Snapshots can be taken online, when the cluster is active and accessible to users. An Ignite snapshot includes a cluster-wide copy of all data records that exist at the moment the snapshot is started. All snapshots are consistent — in terms of concurrent, cluster-wide operations as well as in terms of ongoing changes in Ignite Persistence data, index, schema, binary metadata, marshaller, and other files on nodes. See Ignite documentation to learn about this feature.

Deep Learning With TensorFlow

Even though it was natural to provide machine learning algorithms in Ignite out of the box, another direction was taken for deep learning capabilities. Primarily because machine learning approaches have already been adopted in businesses from big to small -- while deep learning is still being used for narrow and specific use cases.

Thus, Ignite 2.7 can boast about an official integration with TensorFlow deep learning framework that gives a way to use Ignite as a distributed storage for TensorFlow calculations. With Ignite, data scientists can store unlimited data sets across a cluster, gain performance improvements and rely on fault-tolerance of both products if an algorithm fails in the middle of an execution.
