Product Features

#1) IMDB (In-memory Database)

Altibase is an in-memory database with a highspeed and user-friendly architecture. Particularly, it is very helpful to the use cases that demand high throughput and extremely low latency.

#2) Sharding

Sharding is a kind of database portioning that splits huge databases into smaller, faster and more easily managed parts, known as shards.

Altibase offers unique and cutting edge sharding in a manner which permits linear performance enhancement without coordinator related bottlenecks. Thus, while scaling up, there is no performance degradation, regardless of the number of servers being added.

Altibase supports Server-side and Client-side sharding simultaneously to improve performance and compatibility.

#3) Deployment Flexibility

Its flexible deployment mode offers three types i.e. In-memory only, On-disk and Hybrid mode (memory & disk).

#4) Highly Available

Altibase supports highly partitioned tables that can transfer data from disk to memory tablespace and vice versa. It also has properties for specifying the size of character data.

Altibase also provides remote functions for batch processing. These functions can be used only within the stored procedures. Another good feature which ensures high availability is snapshot backup.

It also has a utility called JDBC adapter through which any changed data in Altibase can be applied to other JDBC supported databases. It also offers a support buffer in which a certain amount of x-log is stored. This helps in minimizing the replication of data loss.

#5) Tools and Utilities

Altibase is function and feature-rich by having all the tools and relational capabilities that are required by the enterprise-grade applications. These tools and utilities comprise of the major heads like Productivity & Administration, Interoperability & Migration, and others.

It supports all the functions like Multi-thread Process, LOB, Data Replication, Row-level Locking, Consistent View, DB Recovery, Table, Multi-key Index, Stored Procedure, Stored Function, Sequence, Queue Table, DB Audit, DB Link, Synonym, Table Portioning, User-defined Backup, Online Backup, and Monitoring View.
