1) My testing shows that CassandraCacheStoreFactory is read from xml config
once if the cache name does not exist in Ignite Persistence. It appears that
CassandraCacheStoreFactory bean is persisted along with cache name in Ignite
Persistence Store, CassandraCacheStoreFactory will not be re-instantiated.
So I need to pre-decide dynamicConfigurationReload value. Modifying
dynamicConfigurationReload value later won't take effect at dynamically.
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<property name="name" value="Uom"/>
<property name="atomicityMode" value="TRANSACTIONAL"/>
<property name="cacheMode" value="REPLICATED"/>
<property name="readThrough" value="true"/>
<property name="writeThrough" value="false"/>
<property name="sqlSchema" value="catalog"/>
<property name="cacheStoreFactory">
<bean
class="org.apache.ignite.cache.store.cassandra.CassandraCacheStoreFactory">
<property name="dynamicConfigurationReload"
value ="true" />
<property name="dataSource"
ref="cassandra"/>
<property name="persistenceSettingsBean"
value="catalog_uom_persistence_settings"></property>
</bean>
</property>
</bean>
2) Yes, the similar implementation is applied to data source. Thanks for
remaindering.
3) given dynamicConfigurationReload is only loaded once at very first time
of creating cache, I'm thinking we don't use dynamicConfigurationReload,
instead implement the following
3.1) read data source from the xml config file each time an Ignite server
starts, if data source is not null, use the latest one, else use the
existing one.
3.2) read persistenceSettingsBean from xml config file each time an Ignite
server starts, if persistence settings are not null, use the latest one,
else using the existing one.
3.3) obviously, this is aggressive. But how many times do we start/restart
an Ignite instance. The performance impacts are minimal.
if you think it's okay, I start implementing and testing.
Let me know if you have any other suggestions/recommendations.
Appreciated your help.
