Dear all
Request you to kindly suggest me if my approach is wrong ? The idea of
replacing berkley db with Ignite would not work out if the query is slow ,
whats the best model to be used with Ignite for my usecase.
Thanks,
Rajesh

ve query takes *24 sec* to retrieve the records which we feel
defeats the purpose , our application existing berkley db can retrieve this
faster.
Question is -
a) I have attached my application models & client code , am I doing
something wrong in defining the models and cache configuration. Ri
her Berkley DB node
and continue to work?
Ignite is not just SQL DB, Ignite is a distributed data grid, it's strongly
consistent and HA database,
please make this into account when comparing it with other solutions.
Thanks,
Mike.

Hi,
We are in the process of evaluating Ignite native persistence against
berkely db. For some reason Ignite query does not seem to be performant the
way application code behaves against berkley db
Background:
Berkley db - As of now, we have berkley db for our application and the data
is stored
quot;.IGNITE_DSATTRIBUTESTORE ST__Z2
/* "Ignite_DSAttributeStore".IGNITE_DSATTRIBUTESTORE_ENTRYID_IDX:
ENTRYID = T__Z1.ENTRYID */
ON 1=1
WHERE ST__Z2.ENTRYID = T__Z1.ENTRYID
ORDER BY 1], [SELECT
__C0_0 AS ENTRYID,
__C0_1 AS ATTRNAME,
THanks,
Rajesh
__C0_2 AS ATTR
son')
AND (ENTRYID IS ?1): ENTRYID = ST.ENTRYID
*/
ON 1=1
WHERE ST.ENTRYID = T.ENTRYID
(1 row, 1 ms)
How should I approach that
"Ignite_DSAttributeStore".IGNITE_DSATTRIBUTESTORE full scan can be avoided ?
Thanks in advance.

My bad still I am using the IN clause with variable parameter.
I am exploring other queries.

Hi All,
As of now, we have less than 1 M records , and attribute split into few(3)
tables
with index created.
We are using combination of join & IN clause(sub query) in the SQL query ,
for some reason this query does not return any response.
But, the moment we remove the IN clause and use just

How do we determine the default location for ignite file based DB
Thanks in advance

Hi All,
We have requirement to manage Ignite server and client by the same
application in embedded mode. Whats the way forward?

Hi All,
Wanted to know - what does ignite supports unique or non -unique index.
I have requirement to create non unique index on a field / group of field.
Whats the way?
Also, with the EXPLAIN plan , we can get to know the index used for a
query, sometimes my log is not getting generated
t table name should I specify - I did not create table explicitly, do I
need to that?
How would I create the index?
Thanks,
Rajesh

Hi,
I have requirement that my schema is not fixed , so I have to use the
BinaryObject approach instead of fixed POJO
I am relying on OOTB file system persistence mechanism
My questions are:
- How can I specify the indexes on BinaryObject?
- If I have to use sql query for retrieving objects ,
Hi All,
My query is on substring index working for Ignite. I am using - data grid ,
default file system persistence enabled.
Let us say, I have Organization POJO and index defined on its field as
defined below:
public class Organization {
/** */
private static final AtomicLong ID_GEN =
Hi Val,
Would indices be possible on binary data value , I dont think so. I think I
will stick with the POJO for now.
I have queries on indices and l am not relying on external persistence
system.
a) What are the different indices type Ignite supports apart from equality
i.e does it support the
Yes, correct object is stored as byte array
As my attribute name is not fixed.
I want to have index on different attributes which is not directly visible
as the pojo instance variable

Hi All,
The problem statement is in context of "In-Memory Data Grid" persistence
enabled.
I have requirement/limitation to store the value of a class's object as
byte [] , understood by the application in certain format.

The idea is to replace berkley db apis to Ignite apis to use Ignite as key
value DB.
I could not find any docs for the usage of ignite libraries to be used in
the application.
Any pointers please
