case sensitive Apache ignite.net SQL query

[shuvendu]

Hi,

How to make apache ignite sqlquery to ignore case.

for example

var _arg = new object[] { "%abc%" };

new SqlQuery(typeof(CustomerModel), "CustomerName like ?", _arg)

var _arg = new object[] { "%ABC%" };

new SqlQuery(typeof(CustomerModel), "CustomerName like ?", _arg)

i am getting different results in both the cases

Thanks

Shuvendu

Perfromance Issues when Grid size is more (.Net)

[shuvendu]

We came across a situation where it is taking 10 time more time while
reading records.
Our initial grid size is 390,746 (count) 
Grid size increased to 7,297,301 (count)
Now it is taking 10 times more time.

Re: event when a cache item expired in.Net

[shuvendu]

Hi,

it seems that the event will be thrown if the expired item is accessed. But
in our case we are expecting a logic that will throw event automatically
when the item is expired.

Thanks

Shuvendu
