Altibase Open Source Database Overview

Altibase Database


Altibase is the only hybrid database in the industry that flawlessly combines an in-memory database along with an on-disk database into a single database product using a uniform interface that streamlines data processing for utmost efficiency.

Thus, it eliminates the need to buy an in-memory DB and on-disk DB separately.

Product Features

#1) IMDB (In-memory Database)

Altibase is an in-memory database with a high speed 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 that 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

The 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 only be used within the stored procedures. Another good feature that 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 number of x-logs are stored. This helps in minimizing the replication of data loss.

#5) Tools and Utilities

Altibase is functional and feature-rich by having all the tools and relational capabilities that are required by enterprise-grade applications. These tools and utilities comprise 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, Monitoring View.

#6) Platforms Supported

Altibase is a multi-platform and can be executed on nearly all enterprise OS and platforms.

#7) Interfaces

Supports ANSI SQL-92 and other SQL offered by the other DBMS as well. It is highly compatible with the standard interface.

#8) Programming Languages

In Altibase, multiple programming languages, like C, C+, Java, and all the languages that support ODBC and JDBC are supported.
