Introduction Of altibase In-Memory Database

  • Altibase is an open source , high performance and relational DBMS but is enterprise grade. Altibase has 18 years of experience in serving over 600 enterprise customers including 8  Fortune Global 500 companies.
  • ACID compliant database.
What is an In-Memory Database? An in-memory database (IMDBMS or MMDB) is a database management system (DBMS) that solely utilizes main memory (RAM) to store and manipulate data. The purpose of an in-memory database is to provide blazing fast data processing speeds for online transactional processing and online analytical processing (OLTP/OLAP). For example, Altibase can process over 1.4 million transactions per second (TPS). 

Altibase is an in-memory and hybrid DBMS. Altibase can be adopted and utilized in a hybrid, in-memory only or disk only mode. When your use case demands hundreds of thousands of transactions per second with response rates measured in microseconds, in-memory databases are the only answer. 

Full ACID support:
  • Commits/Rollbacks for transactions
  • The main advantage of using the MVCC model of concurrency control rather than locking is that in MVCC locks acquired for querying (reading) data do not conflict with locks acquired for writing data, and so reading never blocks writing and writing never blocks reading. 
Hardware Costs
  • Altibase outperforms disk-resident databases on identical hardware, potentially mitigating the need to add or upgrade server infrastructure.
  • Altibase has less CPU utilization than most legacy databases, freeing up additional resources for other “useful” works.

Flexible Deployment Mode

  1. In-memory only
  2. On-disk only
  3. Hybrid (memory and disk tables)
