[jira] [Comment Edited] (IGNITE-7285) Add default query timeout
[ https://issues.apache.org/jira/browse/IGNITE-7285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16925649#comment-16925649 ]

-----------------------------------------------------------------
[~samaitra], sorry for a late response. I left a couple of comments on GitHub.
Regarding _unset_ timeout. I think that it would be more straightforward to have a following logic:
* Unset timeout means that a default one should be used.
* Explicitly set timeout must be used.
* Timeout values have the same meaning for {{SqlFieldsQuery.setTimeout}} and {{IgniteConfiguration.setDefaultQueryTimeout}}. Consequently 0 means infinite timeout for both methods.
Technically it can be done in a following way:
# {{SqlFieldsQuery}} declares {{private int timeout = -1}}.
# {{SqlFieldsQuery.setTimeout}} forbids negative arguments.
# Upon {{QueryParameters}} initialization we treat -1 as _unset_ value and use a default one.
A care should be taken when we create {{SqlFieldsQuery}} internally for an execution, like in {{OdbcRequestHandler}}.

> Currently it's possible to provide timeout only on query level. It would be very useful to have default timeout value provided on cache startup. Let's add {{CacheConfiguration#defaultQueryTimeout}} configuration property.
