"Memory saver"

5/5

What do you like best about Hazelcast Platform?

I love the small memory of the library I embedded (since I have many issues with the memory of my pc).

It is also very fast and not complex at all and it saved my all my problems in the distributed systems for sure! Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

Nothing to share about this...I would say as a con that it takes a bit more time in order ro coordinate yourself where and what is located Review collected by and hosted on G2.com.

"Hazelcast is the one of the best tools for every day`s life"

5/5

What do you like best about Hazelcast Platform?

Hazelcast first of all is a really great distributed data grid. You can use distributed collections out of the box like Map, Set, Queue for microservices replicas to share data or for caching purposes. Also, it is possible to take distributed locks to prevent doing the same work simultaneously. The Streaming framework Hazelcast Jet has many needful features and is very fast. Can be run separately from services or as a library. Supports automatic rebalancing and replication. Multiple network options to make a cluster such as multicasting or kubernetes support. Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

It`s a little bit tricky to set up cluster in Kubernetes but it`s a matter of reading the documentation carefully. You should write serializers for objects yourself but it`s your payment for the size of the memory footprint of your cache. Poor search options in in-memory data structures.

"Simple and Powerful Stream Processing Engine"

4.5/5

What do you like best about Hazelcast Platform?

Performance and how it is easy to start implementation. In-memory processing is great adventage, because of high availability. Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

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. Review collected by and hosted on G2.com.

What problems is Hazelcast Platform solving and how is that benefiting you?

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.

"Hazlecast IMDG helped us to reduce service transaction response times by an order of magnitude."

5/5

What do you like best about Hazelcast Platform?

Hazlecast is great because it's distributed data-structures are extensions of commonly used java interfaces. Due to this our team was able to quickly grasp the framework, and implement our solution. Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

At the time I was using this (2017), there weren't much documentation explaining the internal behavior, so we had to dig in to the source code. Review collected by and hosted on G2.com.

Recommendations to others considering Hazelcast Platform:

May be the stateful architectures that Hazelcast presents are not for every situation, as they are hard to manage (talking about DevOps). Use it when there is a dying need for performance. Review collected by and hosted on G2.com.

What problems is Hazelcast Platform solving and how is that benefiting you?

Hazlecast IMDG helped us to reduce service transaction response times by an order of magnitude, by allowing us to process at the data nodes, in memory. This is a huge cut down in network and disk I/O, when comparing to traditional architectures, where all the data is loaded to the service nodes. It also helped us increasing the number of CPUs available for a single transaction, thanks to it's distributed executor service.

"Efficient in-memory database, best when used next to a relation database"

4.5/5

What do you like best about Hazelcast Platform?

I like Hazelcast being configurable to auto back-up features of it. When one of your hazelcast instance is down, remaining instances in the cluster recovers those data from backup and continue working where it left. Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

I can't think of anything I don't like about Hazelcast IMDG, maybe the pricing would be the worst side of it. Review collected by and hosted on G2.com.

Recommendations to others considering Hazelcast Platform:

I used Hazelcast embedded to the services. However, stand-alone usage of Hazelcast might provide a better/more sustainable cluster. Review collected by and hosted on G2.com.

What problems is Hazelcast Platform solving and how is that benefiting you?

Hazelcast is solving our caching problem and fastens the data access time. It also makes it possible to spend less time on managing instances of cache. The instances can discover each other and communicate as default. Review collected by and hosted on G2.com.

We enjoyed using hazel cast cluster for one of the highly scalable SaaS applications serving 2 million transactions every minute

Hazel cast was very stable and we loved it Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

We used Hazel cast back in 2013-2015 and those days I felt there were multiple opportunities to improve further. Some of those improvements which we had suggested didn't get implemented even after a a couple of years. Review collected by and hosted on G2.com.

Performance, ease-of-use, and JVM friendliness Review collected by and hosted on G2.com.

What do you dislike about Hazelcast Platform?

Hazelcast implementation requires application changes. However, solutions like the Heimdall Proxy can manage Hazelcast clusters by providing the caching and invalidation logic for Hazelcast. Review collected by and hosted on G2.com.

The Heimdall Database Proxy provides the caching and invalidation for Hazelcast. You can create a SQL cache subsystem in minutes without any code changes. Review collected by and hosted on G2.com.
