Learning about data stores
Learn about many aspects of a
data store.
Subtopics
Data stores A data store is
a message store that contains a
set of tables that are in the same database schema. A messaging engine uses
a data store to store operating
information in the database, as well as to preserve essential objects that
the messaging engine needs for recovery
in the event of a failure.
Data store life cycle
Starting and deleting a messaging engine affects the life
cycle of its data store. Appropriate actions must be carried out on
the data store.
Data store high availability considerations When running a messaging engine in
a cluster such that the messaging engine can
failover from one server to another, note a number of considerations.
Data store exclusive access A
messaging engine establishes a lock on its data store so that it has exclusive
access to the data stored within. This ensures integrity of the data within
the data store. Note that several factors can affect exclusive access locking
in practice.
Data store performance Several factors can affect the performance of a data store,
when data store is chosen as
the message store for a messaging engine.
For example, operations on databases.
