Package com.splicemachine.pipeline.foreignkey Description

Foreign Key Handling Strategy Child Writes buffer all parent checks and narrow them down to distinct checks. These checks are performed in parallel against the parent only after the write occurs to the children. The check algorithm is conservative in checking both the actual value (Snapshot Isolation) and any values in flight (Read Uncommittted). Parent Deletes immediately check for children elements prior to writing their delete. The check algorithm is conservative in checking both the actual value (Snapshot Isolation) and any values in flight (Read Uncommittted) utilizing the foreign key index of the child element. It would be nice in the future if foreign keys did not require an index be created.
