Difference Between Hazelcast vs Ignite
Hazelcast is defined as an in-memory distributed caching mechanism that is a data grid and written in Java which is used to access data faster directly from memory instead of a database. It stores data in memory in key-value based on having its own map key-value space, it also stored the data in a distributed architecture. It also multicasting to identify the cluster whenever new nodes join if you don’t want multicasting you can connect using TCP/IP and hazelcast also can be integrated into the spring framework. Whereas, Ignite is a memory-centric platform to combining in-memory key-value data grid with a distributed SQL database that can be extracted conveniently between a users’ application layer and data layer for high performance, by using ACID transactions and also it is highly available and horizontally scalable.

Key Differences of Hazelcast vs Ignite
Below provided are the major key differences between these two.
Scalable
Haselcast is a highly scalable data distribution environment whereas ignite is an open-source distributed, caching, and processing platform. Hazelcast having its various distributed data structures, distributed caching capabilities, elastic nature, Memcache support, integration on the other hand ignite have transactional, analytical, and streaming workloads. Ignite has different APIs to interact with the database whereas hazelcast is an auto database tool that allows connecting with an existing database. Haselcast replicates data across the cluster, as it is scalable we can join hundreds of nodes in a cluster, and ignite replication is very weak with the support of JV107.
Memory-Centric
Hazelcast is distributed in-memory data grid platform for java and ignite is memory-centric which is distributed in a database platform. Ignite having memory components and RAM for storage as hazelcast does not have memory components so that ignite is the alternate for hazelcast. Ignite has off-heap memory to the allocation of memory region outside of the java heap, in hazelcast, there is a huge density of memory storage, and allocation of memory is inside the java heap.
SQL support
Hazelcast is not joined compatible on the other hand ignite has distributed joins across the caches. Hazelcast supports key constraints whereas ignite does not support key constraints. Hazelcast have its own key-value space and data stored in nodes based, whereas ignite store data in memory in key-value based indexes. Ignite can interact with the database by JDBC or ODBC.
Comparison Table of Hazelcast and Ignite
| S. No | Hazelcast | Ignite |
| 1 | Hazelcast replication strategy supports JCache(JSR107), the main purpose of JSR107 is to partition the caches with a strong consistency of replicating caches so hazelcast having Strong consistency. | Whereas ignite strategies also support JCache(JSR107), portioned caches, and data replication but ignite having weak consistency. |
| 2 | Hazelcast is having a very high density of memory store which allocates the memory into the same process inside of java heap. Hazelcast does not have Join or we can say hazelcast does not have Join capability. | Ignite uses off-heap memory to allocate the memory region outside of the java heap. Whereas ignite has distributed Joins across the caches. |
| 3 | Hazelcast’s cache queries have only on-heap indexes. Hazelcast was Implemented in Java and run on JVM.
|
Ignite’s cache queries have on-heap and off-heap indexes both. Ignite Implemented in C++, Java, Dot Net and run on Linux, OS X, Solaris, Windows, etc server operating systems. |
| 4 | Hazelcast is used by some of the companies that are Yammer, Seat Pagine Gialle, and Stormpath. Hazelcast runs only AND/IN/LIKE/BETWEEN SQL queries. | Whereas, Ignite is used by LabNetwork, Element Analytics, and Leads Software companies. Ignite runs full SQL-99 queries
compliance. |
| 5 | Hazelcast supported the programming languages are, .Net, C#, C++, Clojure, Go, Java, JavaScript(Node js), python, Scala | Ignite supported to the programming languages are, C#, Java, PHP, Python, Ruby, Scala. |
| 6 | Hazelcast you can download at ‘hazelcast.org’, also provides a new version that adds advanced levels of capabilities around business continuity, security, and scalability. Hazelcast having 3.25K GitHub starsand 1.18K forks on GitHub. | Ignite can download free with a white paper entitled “Introduction to Apache Ignite” and an in-depth of Ignite architecture, APIs features, and use cases are given. Ignite having 2.67K GitHub stars and 1.3K GitHub forks. |
| 7 | Hazelcast gives central, predictable scaling of applications through in-memory access to frequently used data and these techniques can decrease the query load on databases and speed can be improved. | Whereas ignite provides a distributed in-memory data store that delivers in-memory speed and unlimited read and write scalability to applicants.
|
| 8 | A Data Grid is a system that collected multiple servers that work together to manage information and related operations as computations. | Ignite is an in-memory computing platform that can be placed perfectly between a user’s application layer and the data layer. |
| 9 | Hazelcast is horizontally scalable, so you can join with more than one node in a bunch to aggregate terabytes of RAM to keep all your data in memory. Hazelcast copying data across the cluster, so it has no single point of failure. | Apache Ignite loads data from the existing disk-based storage layer into RAM, improving performance by as much as six orders of magnitude (1 million-fold).
|
| 10 | Hazelcast is high throughput and low latency requirements in memory that compute on the platform that runs applications. Hazelcast has a big acceptance, which is
stated in 35 company stacks & 81 developers stacks.
|
Ignite can run on-premises, on cloud platforms such as AWS and Microsoft Azure, or in a hybrid environment. Ignite is listed in 4 company
stacks and 4 developer stacks. |
Conclusion – Hazelcast vs Ignite
In this article, we conclude that Hazelcast and Ignite both are open source database tools. We also see that Ignite is widely used and it is in progress all time and the most important thing is that ignite indexing is more knowledgeable than hazelcast and ignite having so many features and functionality and is very simple to use. Hazelcast is the alternative for Ignite.
