Hi,
Annotations and QueryEntities are just different ways of specifying the
config.
There should be no differences in how that config is being deployed
inside Ignite.
Currently there is no way to set a table name via annotations. It
defaults to the name of the class.
see:
Hi.
Can you share both xml configuration and class with entities?
>The difference is the second one will create H2 database table. Then H2
will keep another copy so that it is using double size of memory ?
No, h2 doesn't store a copy of data. Moreover, annotations are used to
prepare
Hello, trying to load 17m record size of data, size is 3.4G. if pojo
class field defined with QuerySqlField annotation, Ignite will use
roughly 9G memory. If we create ignite cache as database table with
QueryEntity / QueryField, it will use total 20G memory.
The difference is the second one
Hi Angel,
Thanks for sharing your plugin with the community! It's highly likely that
there some folks on the user list who will be glad to know the plugin is
available.
We also supported you by sharing the integration via Ignite twitter handle:
Hi,
When running your code I created the cache as follows:
IgniteCache employeeCache =
ignite.getOrCreateCache("employeeCache").withKeepBinary();
With the ".WithKeepBinary()" flag set code works, otherwise there are
serialization errors.
If you still get errors w/this flag set,
Hello Mods/ Admin,
not sure if this is the right place to post the plugin I'm developing for
Tibco BW.
If it's not, kindly mre to the right section.

Yes, you can. You just need to combine C++ PutGet example and ODBC example,
where from C++ you take a part that puts data in cache, and from ODBC you
take
the querying part.

Hi,
All data regions allocate offheap memory separately, so, it will be an
additional 500mb to 20% of the default region. Also, size of the default
region can be configured too.

Hi Igniters!
Major changes that are going to be contributed from our side for IGNITE SQL:
- Local runtime statistics which helps to estimate query execution plan.
It should help use right join order in most cases. Seems could be done by
Q3.
- most efforts will be direct to new SQL
Hi
Currently we are using ignite as an in-memory cache.We are now trying to
explore the ignite persistence to avoid reloading the caches whenever the
cluster restarts.
Had a walk through of the documentation and have one question.Can any one
help me answer the following question.

Hi everyone!
Major changes that are going to be contributed from our side:
- https://issues.apache.org/jira/browse/IGNITE-11704 - keeping tombstones
for removed entries to make rebalance consistent (this problem is solved by
on-heap deferred deletes queue so far).

Hi All,
I think I have figured it out. I just need to specify the schema.
thanks.
