Mirza Aliev updated IGNITE-20599:
---------------------------------
Description:
*Motivation*
In https://issues.apache.org/jira/browse/IGNITE-20561 we need to create a
condition for a ms invoke with NOT_TOMBSTONE. We could do this like this:
{code:java}
and(
notExists(dataNodes(zoneId)),
notTombstone(dataNodes(zoneId))
){code}
But there are no `notTombstone` in the meta storage dsl.
I propose to implement `notTombstone` operation.
*Definition of done*
`notTombstone` operation is implemented.

*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.
