---------------------------------------
Summary: Implement correct limit for TextQuery
Key: IGNITE-12189
URL: https://issues.apache.org/jira/browse/IGNITE-12189
Project: Ignite
Issue Type: Improvement
Components: general
Reporter: Yuriy Shuliha
Assignee: Yuriy Shuliha
Fix For: 2.7.6
PROBLEM
For now each server-node returns all response records to the client-node and it
may contain ~thousands, ~hundred thousands records.
Event if we need only first 10-100. Again, all the results are added to queue
in _*GridCacheQueryFutureAdapter*_ in arbitrary order by pages.
There are no any means to deliver deterministic result.
SOLUTION
Implement _*limit*_ as parameter for _*TextQuery*_ and
_*GridCacheQueryRequest*_
It should be passed as limit parameter in Lucene's _*IndexSearcher.search()*_
in _*GridLuceneIndex*_.
For distributed queries _*limit*_ will also trim response queue when merging
results.
Type: long
Special value: : 0 -> No limit (Long.MAX_VALUE);
