Hazelcast Jet

Hazelcast Jet is a high performance stream processing engine designed for building applications with extremely high throughput and low latency requirements. It supports both stream and batch processing through a pipeline API that models each job as directed acyclic graph (DAG), which lay out the tasks of a job and how they interact. It then optimizes the DAG to leverage parallelism for performance and efficiency of jobs based on the available resources in the cluster. Hazelcast Jet can be used in conjunction with Hazelcast IMDG, in which IMDG acts as a high speed data store to enable lookups that enrich the streamed data.

Simple and Powerful Stream Processing Engine

What do you like best?

Performance and how it is easy to start implementation. In-memory processing is great adventage, because of high availability.

What do you dislike?

Documentation is not as good as for Hazelcast IMDG and sometimes I do not know where I can find some information I am looking for.

What problems are you solving with the product? What benefits have you realized?

We needed Stream processing platform which allow to connect to Kafka and generate some output based on Python scripts provided by business analitycs. Jet allowed us to get messages from Kafka, translate them, enrich with data from software based on another Hazelcast IMDG, execute Python scripts and generate expected output.
