Ignite SqlQuery for two clients - sql

Question

I use next process for my Ignite cache with third party persistence:
empty database
start two instances in server mode
start first instance in client mode.
The client in cycle
creates entities
reads entities by a simple SqlQuery
So far all right. All the code works properly.
Then I start second instance in client mode. The code is the same.
The second client also in cycle
creates entities
reads entities by the SqlQuery
And the second client gets empty ResultSet. While the first client still reads the data properly. BTW. Both clients can get entities by keys.
Off course all the data in memory.
So why the second client can't read by SqlQuery?
Three options of code are below. All of them work identically: The first started client always gets correct result. The second started client always gets empty ResultSet.
SqlQuery<EntryKey, Entry> sql = new SqlQuery<>(Entry.class, "accNumber = ?");
sql.setArgs(number);
List<Cache.Entry<EntryKey, Entry>> res = entryCache.query(sql).getAll();
...
SqlFieldsQuery sql = new SqlFieldsQuery("select d_c, summa from Entry where accNumber = ?");
sql.setArgs(number);
List<List<?>> res = entryCache.query(sql).getAll();
...
SqlQuery<BinaryObject, BinaryObject> query = new SqlQuery<>(Entry.class, "accNumber = ?");
QueryCursor<Cache.Entry<BinaryObject, BinaryObject>> entryCursor = binaryEntry
.query(query.setArgs(number));
List<javax.cache.Cache.Entry<BinaryObject, BinaryObject>> res = entryCursor.getAll();
XML configuration is below:
<bean class="org.apache.ignite.configuration.CacheConfiguration">
<!-- Set a cache name. -->
<property name="name" value="entryCache" />
<!-- Set cache mode. -->
<property name="cacheMode" value="PARTITIONED" />

Answer 1

In case of a Third party store, readThrough works only for key-value API, for SQL you need to run loadCache method before performing queries on Ignite.
If you want to use read from disk with persistence, I would recommend using Ignite native persistence store: https://apacheignite.readme.io/docs/distributed-persistent-store
Also, I see in you configuration:
<property name="indexedTypes" value="true" />
It's definitely a mistake, it should be configured like:
<property name="indexedTypes">
<list>
<value>java.lang.Integer</value>
<value>java.lang.Long</value>
</list>
</property>
IndexedTypes and QueryEntity configure the same things, actually, internally, IndexedTypes will create a configuration of QueryEntity. So, it's redundantly to configure both.

Answer 2

Thanks to everyone for suggestions.
I achieved an option which gives a stable and correct result.
Actually I moved the field accNumber from the key class to the value class. So now select is filtered against a primitive field of the value class.
Query configuration:
<bean class="org.apache.ignite.cache.QueryEntity">
<!-- Setting indexed type's key class -->
<property name="keyType"
value="ru.raiffeisen.cache.repository.EntryKey" />
<!-- Setting indexed type's value class -->
<property name="valueType" value="ru.raiffeisen.cache.repository.Entry" />
<!-- Defining fields that will be either indexed or queryable. Indexed
fields are added to 'indexes' list below. -->
<property name="fields">
<map>
<entry key="accNumber" value="java.lang.String" />
<entry key="key.d_c" value="ru.raiffeisen.cache.repository.EntryKey.DEB_CRE" />
<entry key="key.valuedate" value="java.util.Date" />
<entry key="summa" value="java.lang.Integer " />
</map>
</property>
<!-- Defining indexed fields. -->
<property name="indexes">
<list>
<!-- Single field (aka. column) index -->
<bean class="org.apache.ignite.cache.QueryIndex">
<constructor-arg value="accNumber" />
</bean>
</list>
</property>
</bean>
