Hi all,
WSO2MB currently maintains two types of storage modes for slot management
from which the user can configure the broker to run in.
The configuration in broker.xml is as follows:
<slotManagement>
<!--Set slot storage mode (RDBMS/HazelCast)-->
<storage>HazelCast</storage>
</slotManagement>
The idea is to make 'RDBMS' the default storage mode for slot management.
The reasons which triggered the decision are as follows.
- Whenever something goes wrong, we could identify the problem by
looking at the database if we use RDBMS since it is persistent
- There is a risk of Hazelcast maps leading to an inconsistency in the
scenario of a network partition
- Memory being filled due to serialized objects created by Hazelcast
Therefore we have decided to perform slot management using RDBMS by
default. Any comments and suggestions are highly appreciated.
Thank you
