Thanks Denis…
I understand that the example mentioned in the link is querying on the entity
named Person
CacheConfiguration<Long, Person> cacheCfg = new CacheConfiguration<>();
...
cacheCfg.setName("mycache");
// Setting up query entity.
QueryEntity queryEntity = new QueryEntity();
queryEntity.setKeyType(Long.class.getName());
queryEntity.setValueType(Person.class.getName());
But we are using Binary Objects and we will not have a definite entity unlike
Person.
And our exact use case is to perform cross joins on mongo collections.
As we couldn’t perform complex joins using mongo, we are planning to load all
the mongo collections to ignite and perform joins inmemory.
The only option to load mongo collections to inmemory is to create binary
object. But we are now stuck with the querying part.
Please help.

Sriveena,
You should configure corresponding query entities to be able to query data in
cache.
Annotation driven configuration is also available.

Hi Denis,
I am trying to use the below code to query the binary object
IgniteCache<Integer, BinaryObject> cache =
start.getOrCreateCache(cfg).withKeepBinary();
BinaryObjectBuilder builder = start.binary().builder("BinaryTest");
builder.setField("name", "Test");
cache.put(1, builder.build());
QueryCursor<List<?>> query = cache.query(new SqlFieldsQuery("select name
from BinaryTest"));
But it is failing in latest 2.5 version saying BinaryTest Table does not exist.
How do we query the binary objects in the above example?
Please help.

Sriveena,
You can have objects of different types in one cache, but querying it will be
tricky.
You will have to configure
QueryEntities<https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapacheignite-sql.readme.io%2Fdocs%2Fschema-and-indexes%23section-queryentity-based-configuration&data=02%7C01%7CSriveena.Mattaparthi%40ekaplus.com%7C6e1e06d9d5c0452da8da08d5dc2ee46a%7C2a5b4e9716be4be4b2d40f3fcb3d373c%7C1%7C0%7C636657016326903455&sdata=Z093el7e%2Fj%2BngjoDdJjUwWNUWfPu4Yb0OZgKv3ZEiis%3D&reserved=0>
for your data, that will describe, which fields are available for querying.
Annotation based
configuration<https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapacheignite-sql.readme.io%2Fdocs%2Fschema-and-indexes%23section-queryentity-based-configuration&data=02%7C01%7CSriveena.Mattaparthi%40ekaplus.com%7C6e1e06d9d5c0452da8da08d5dc2ee46a%7C2a5b4e9716be4be4b2d40f3fcb3d373c%7C1%7C0%7C636657016326903455&sdata=Z093el7e%2Fj%2BngjoDdJjUwWNUWfPu4Yb0OZgKv3ZEiis%3D&reserved=0>
is also available.
Querying nested object is also possible, if you configure the query entities
properly:
https://apacheignite-sql.readme.io/docs/schema-and-indexes#section-indexing-nested-objects<https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fapacheignite-sql.readme.io%2Fdocs%2Fschema-and-indexes%23section-indexing-nested-objects&data=02%7C01%7CSriveena.Mattaparthi%40ekaplus.com%7C6e1e06d9d5c0452da8da08d5dc2ee46a%7C2a5b4e9716be4be4b2d40f3fcb3d373c%7C1%7C0%7C636657016326903455&sdata=1amkW4husY1fLSN%2FKtEBx8app5u%2FkUJhqiA4JCYgQ0o%3D&reserved=0>
So, if you want to run SQL queries over your data, it should have some concrete
schema.

Thank you so much for the quicker responses unlike any other forums..I really
appreciate that.
One last question Denis, we have plan to load all the mongodb collections to
ignite cache and perform complex aggregations and join in memory.
But Unlike any RDBMS data stores we cannot have fixed model objects for each
collections as each document in the collection may have its own columns and
datatypes.
Could you please suggest, if ignite is the choice for this kind of scenario
where same mongo collection have different type of data.
Please note that we have tried using BinaryObject, but we are stuck that ignite
doesn’t support querying on the inner binaryobject.( binaryobject inside a
binaryobject – sub documents, array inside a mongo document)

It works the same way with MySQL or any other relational DB.
So, CacheStore gives you a possibility to implement synchronization with any
external data source. You can do it for MongoDB, if you need.

Subject: Re: Information regarding Ignite Web Console
Sriveena,
Web Console can generate schema in Ignite based on an existing schema in a
relational database.
But you can do it yourself, without use of Web Console.
Web Console only makes it easier to wire-up stuff, i.e. generate required data
classes and configuration.
Unfortunately, this feature is not available for NoSQL databases. But you still
can configure everything yourself.
You will need to implement a
CacheStore<https://apac01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fignite.apache.org%2Freleases%2Flatest%2Fjavadoc%2Forg%2Fapache%2Fignite%2Fcache%2Fstore%2FCacheStore.html&data=02%7C01%7CSriveena.Mattaparthi%40ekaplus.com%7Cf4918a96e28644d507b908d5dc1491ba%7C2a5b4e9716be4be4b2d40f3fcb3d373c%7C1%7C0%7C636656903279754570&sdata=V09AYASdhDUexLS4ZNs44zvEWjJ1lmZFqjVRwQft2xs%3D&reserved=0>,
