Hi all,
What is the use-case for `OnConflictStrategy.ABORT`  or `OnConflictStrategy.IGNORE`  *specifically for `@Update`* ?

My understanding is for `@Insert` , if there is an existing data matching the given primary key, it creates a conflict and we can resolve using
```ABORT - to abort the transaction. The transaction is rolled back.
IGNORE - An Insert DAO method that returns the inserted rows ids will return -1 for rows that are not inserted since this strategy will ignore the row if there is a conflict.
REPLACE - An Insert DAO method that returns the inserted rows ids will never return -1 since this strategy will always insert a row even if there is a conflict.```
But, since `@Update` is used to modify existing data, what is the use-case for `OnConflictStrategy.ABORT`  or `OnConflictStrategy.IGNORE` ?
`OnConflictStrategy.REPLACE` will allow us to update the data as I expect.
