LINQ
Pavel Tupitsyn created IGNITE-4425:
--------------------------------------
Summary: .NET: Support "Array.Contains" in LINQ
Key: IGNITE-4425
URL: https://issues.apache.org/jira/browse/IGNITE-4425
Project: Ignite
Issue Type: Improvement
Components: platforms
Reporter: Pavel Tupitsyn
Fix For: 2.0
SQL supports IN queries and, as a better alternative, temporary table join, as described in the docs:
https://apacheignite.readme.io/docs/performance-and-debugging#performance-and-usability-considerations
Example SQL:
{code}
new SqlFieldsQuery("select p.name from Person p join table(id bigint = ?) i on p.OrgId = i.id", new object[] { new object[] {1,3}})
{code}
Add support in LINQ like this:
{code}
persons.AsCacheQueryable().Where(x => new[] {1,3}.Contains(x.Value.OrgId))
{code}
