John,
It's not necessary to have class at all, you can specify any type, you just
need to use this type when creating binary object for this key.

I just used two columns as primary key...
Of I use key_type and specify a type does that class need to exist in the
class path of the server nodes?
Like if I have
class MyKeyClass {
Integer col1;
Integer col2;
}
Does this class need to be loaded in all nodes or ignite can figure it out
an
Hi,
There is no guarantee of data consistency between Ignite persistence and
3rd party DB in this case. Storages will be synchronized in case of one of
the node failure. You can try to run some explicit checking for data
consistency, but I believe it won't be easy with the load.

Hi John,
To do this, you need to create a key object with the same type as you have
for the table. If you don't specify KEY_TYPE in the create table script, it
will be generated automatically. I would recommend to specify it for the
command(just type name, if you don't have a class) and, when you
Hi, the following setup should reproduce the issue:
A server class starts up a server node with the config in my original mail
(eg 3 servers, partitioned with 1 backup). In that class, at the end do
something like:
ignite.events(ignite.cluster().forServers()).localListen(ignitePredicate,
Hi,
I am exploring ways to do data backup along with native persistence. Is it
possible to achieve this using cache store implementation. So that data will
be persisted in disk as well as replica copy.
Thanks,

Hi, I have an SQL table
create table if not exists my_table (
column1 int,
column2 int,
column3 varchar(16),
PRIMARY KEY (column1, column2)
) with "template=replicatedTpl";
and I'm creating my near cache as follows...
IgniteCache myCache;
NearCacheConfiguration nearConfig = new

Hi,
Indexes are stored in the same place as the data, in a file called
index.bin
You can't change the relative location of the index file(s). Only the
storage path/wal path/wal archive
path(s) could be specified.
See:
https://apacheignite.readme.io/docs/distributed-persistent-store#configu
Hi All,
I have read that it is a good idea to have wal, walarchive and data on
separate drives. How about indexes? How would you specify the path for the
indexes?
Is the idea to specify the data and indexes on one drive and wal/walarchive
on another?
thanks.
