Mirza Aliev updated IGNITE-20599: --------------------------------- Summary: Implement a 'NOT_TOMBSTONE' operation in the meta storage dsl. (was: Implement a 'not' operation in the meta storage dsl.) > Implement a 'NOT_TOMBSTONE' operation in the meta storage dsl. > -------------------------------------------------------------- > > Key: IGNITE-20599 > URL: https://issues.apache.org/jira/browse/IGNITE-20599 > Project: Ignite > Issue Type: Improvement > Reporter: Sergey Uttsel > Priority: Major > Labels: ignite-3 > > *Motivation* > In https://issues.apache.org/jira/browse/IGNITE-20561 we need to create a > condition for a ms invoke with negation. We could do this two ways: > {code:java} > and( > notExists(dataNodes(zoneId)), > notTombstone(dataNodes(zoneId)) > ){code} > or > {code:java} > not( > or( > exists(dataNodes(zoneId)), > tombstone(dataNodes(zoneId)) > ) > ){code} > But there are no `notTombstone` or `not` methods in the meta storage dsl. > > I propose to implement `not` operation because it is more general approach > and it can be reused with other conditions. > *Definition of done* > `not` operation is implemented. -- This message was sent by Atlassian Jira (v8.20.10#820010)
