From #162:
It's a perfect example of why “let's add this code to the library because another project may need to use it” is a bad idea. |

There still seems to be references to this in docs: https://github.com/doctrine/dbal/blob/2.11.x/docs/en/reference/sharding.rst#schema-operations-schemasynchronizer-interface Should these docs have been removed, or maybe marked as deprecated in #3905 ? IMO we should not advertise deprecated features. |

Well, we're not necessarily advertising them, it's just documentation. I'll make sure it's removed during the up-merge. In any event, the whole "Sharding" section will be removed from the documentation, not only this specific API. |

I mean that we should maybe remove it from 2.11.x too, or at least make it clear that sharding is deprecated in the docs |

Removing documentation for the existing code looks odd to me.
We haven't been doing this for any other deprecations, so we're at least consistent here. Otherwise, there's a lot more to update than just this. UPD: in fact, what the right approach is depends on what type of documentation that is. It would indeed make sense to remove it from a How-To or a Tutorial but kept in Explanation or Reference. Ours is all-in-once, so there's no right or wrong answer. |

Nice resource, thanks for sharing it! |

I suggest we take the same approach as for sharding: don't make any documentation changes during the deprecation (#3905) and removed the documentation during the code removal (#3906). If we want to change this process, it's out of the scope of this issue and should be done separately. |

On the other hand, we do have some APIs (e.g. platforms) marked as deprecated in the documentation. But it's more of an exception than a rule: I went ahead and updated the documentation on |

Summary
The
SchemaSynchronizerAPI was introduced as part of the support for sharding (#162) which is now deprecated (#3905). This code hasn't received any functional changes in the last 8 years (12f381f) and doesn't seem to be used by any open source projects.According to the tests and the implementation,
SingleDatabaseSynchronizeris just a wrapper over other schema-related APIs and doesn't provide any additional functionality.
