             Summary: Support JDBC API for savepoint
                 Key: IGNITE-28649
                 URL: https://issues.apache.org/jira/browse/IGNITE-28649
             Project: Ignite
          Issue Type: Improvement
            Reporter: Vladislav Pyatkov
            Assignee: Vladislav Pyatkov


h3. Motivation
We already have the savepoint API for KV and SQL. JDBC has its own 
specification of transaction endpoints.
There are methods:
{code}
conn.setSavepoint()
conn.setSavepoint("sp1")
conn.rollback(sp)
conn.releaseSavepoint(sp)
{code}

h3. Implementation notes
If we support savepoint API, the method 
{{DatabaseMetaData.supportsSavepoints()}} should return true.

h3. Definition of done
JDBC client supports all built-in savepoint APIs.
