Aerospike vs Elasticsearch: What are the differences?
Introduction
Aerospike and Elasticsearch are two popular database systems used for different purposes. While Aerospike is a high-performance NoSQL database, Elasticsearch is a distributed search and analytics engine. Here are the key differences between these two technologies:
1. Data Model:
Aerospike follows a key-value data model, where data is stored and retrieved based on a primary key. On the other hand, Elasticsearch utilizes a document-oriented data model, where data is stored in JSON-like documents and can be queried using full-text search.
2. Search Capabilities:
While both Aerospike and Elasticsearch offer search capabilities, Elasticsearch is designed specifically for searching and achieving high speeds in searching large volumes of data. It supports advanced search features like fuzzy search, autocomplete, and search across multiple fields. Aerospike, on the other hand, focuses more on high-performance data processing rather than search functionalities.
3. Scalability:
Both Aerospike and Elasticsearch are designed to be scalable, but they handle scalability in different ways. Aerospike uses a shared-nothing architecture, where data is distributed and replicated across multiple nodes. It offers automatic data partitioning and replication, making it horizontally scalable. Elasticsearch, on the other hand, uses a distributed architecture with a cluster of nodes. It allows for horizontal scaling by adding more nodes to the cluster and automatically redistributes data across the nodes.
4. Consistency and Durability:
Aerospike guarantees strong consistency and durability by default. It ensures that all nodes in the cluster agree on the state of data and provides various options for durability, including synchronous replication. Elasticsearch, on the other hand, focuses more on availability and eventual consistency. It allows for distributed system failures by providing configurable consistency levels and relies on eventual consistency for performance optimization.
5. Data Replication and Backup:
Aerospike offers multi-node data replication and automatic data backup, ensuring data availability and recovery in case of node failures. Elasticsearch also supports data replication and backup, but it provides additional features like snapshot and restore, which allow taking incremental backups and restoring data even across different clusters.
6. Use Cases:
Aerospike is commonly used in applications requiring low-latency or real-time data processing, such as real-time bidding, fraud detection, and recommendation systems. Elasticsearch, on the other hand, is widely used for full-text search, log analysis, and data analytics, especially in applications dealing with large volumes of textual data.
In summary, Aerospike is a high-performance NoSQL database with a key-value data model, while Elasticsearch is a distributed search and analytics engine with a document-oriented data model. Aerospike focuses more on data processing performance, strong consistency, and durability, while Elasticsearch excels in search capabilities, scalability, and handling large volumes of textual data.
Hey everybody! (1) I am developing an android application. I have data of around 3 million record (less than a TB). I want to save that data in the cloud. Which company provides the best cloud database services that would suit my scenario? It should be secured, long term useable, and provide better services. I decided to use Firebase Realtime database. Should I stick with Firebase or are there any other companies that provide a better service?
(2) I have the functionality of searching data in my app. Same data (less than a TB). Which search solution should I use in this case? I found Elasticsearch and Algolia search. It should be secure and fast. If any other company provides better services than these, please feel free to suggest them.
Thank you!
Hi Rana, good question! From my Firebase experience, 3 million records is not too big at all, as long as the cost is within reason for you. With Firebase you will be able to access the data from anywhere, including an android app, and implement fine-grained security with JSON rules. The real-time-ness works perfectly. As a fully managed database, Firebase really takes care of everything. The only thing to watch out for is if you need complex query patterns - Firestore (also in the Firebase family) can be a better fit there.
To answer question 2: the right answer will depend on what's most important to you. Algolia is like Firebase is that it is fully-managed, very easy to set up, and has great SDKs for Android. Algolia is really a full-stack search solution in this case, and it is easy to connect with your Firebase data. Bear in mind that Algolia does cost money, so you'll want to make sure the cost is okay for you, but you will save a lot of engineering time and never have to worry about scale. The search-as-you-type performance with Algolia is flawless, as that is a primary aspect of its design. Elasticsearch can store tons of data and has all the flexibility, is hosted for cheap by many cloud services, and has many users. If you haven't done a lot with search before, the learning curve is higher than Algolia for getting the results ranked properly, and there is another learning curve if you want to do the DevOps part yourself. Both are very good platforms for search, Algolia shines when buliding your app is the most important and you don't want to spend many engineering hours, Elasticsearch shines when you have a lot of data and don't mind learning how to run and optimize it.
Rana - we use Cloud Firestore at our startup. It handles many million records without any issues. It provides you the same set of features that the Firebase Realtime Database provides on top of the indexing and security trims. The only thing to watch out for is to make sure your Cloud Functions have proper exception handling and there are no infinite loop in the code. This will be too costly if not caught quickly.
For search; Algolia is a great option, but cost is a real consideration. Indexing large number of records can be cost prohibitive for most projects. Elasticsearch is a solid alternative, but requires a little additional work to configure and maintain if you want to self-host.
Hope this helps.
