Oracle Coherence is the industry leading in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data

Basics of Coherence

TURKCELL DAHİLİ

Types of Usage

Data Transfer

Active-Passive Process of multiple applications

Storage-Enrichment

Assurance of dataflow

Coherence Usage in RBM

TURKCELL DAHİLİ

Data Transfer

Each application has a CQC(Continuous Query Cache)

Each application has an input queue(Blocking Queue)

Each application redirects/deletes Cache Item

Coherence Usage in RBM

TURKCELL DAHİLİCoherence Usage in RBM

Data Transfer

Application reads items from DB

Each application adds its identity into «Application Registry» cache

Application sets their «next dest» area by Round Robin(load balancing) and inserts into the cache

Storage-Enrichment

Storage cache , we use, are for preventing unnecessary outer systemcalls

TURKCELL DAHİLİCoherence Usage in RBM

Storage-Enrichment

Enrichment cache includes 35M items which are consist of outer system data(54 GB memory usage in 9 nodes over 3 machines)

In order to prevent unnecessary system calls, events are enriched with outer system data

TURKCELL DAHİLİCoherence Usage in RBM

Assurance of Data Flow

In order to prevent data loss and functually operate replays/retrys of data, events are being stored temporarily

Each application is responsible to remove the item which is being processed by itself

A filter operates over cache periodicly to get the items which have not been processed

Result of the filter , items which have not been processed yet, are sent into the process again

TURKCELL DAHİLİConclusion

RBM is a very important project for Turkcell

The expectation from RBM is getting higher each day

Coherence Cache has a major role in this state of RBM

We used Coherence in a lot of place of the project for different purposes

In order to increase performance, more usage of Coherence will be needed in the future
