Hi,
Sorry for late response,
I tried to use and working fine, but my architect told try to use without aggregate and reason behind I don't know, that is the reason im tying it without aggregate,
will update in the post if anything comes positive results |
The only good reason I can think of for that is nominally performance. Using ESQL code to build an aggregated structure is "lighter weight" than using aggregation nodes.
But your architect should have explained the reason for it to you. Or simply not made technical design decisions and kept to architecture.

You should push back and ask the architect why he's asking you to reinvent the wheel.

You'd need some extremely tight code to outperform the inbuilt compiled product code.

I forget (never learned) about how aggregation works in v10, but in previous versions, it incurred the performance hit of going to a queue and then coming back out.
At least, a "performance hit" by some views.

Quite so, but the cost of the operation you correctly described is small. Smaller than (for example) the indexed ESQL the OP described at the start of this thread.
