---------------------------------
Summary: Provide TopologySpec storage backed by MySql
Key: GOBBLIN-1562
URL: https://issues.apache.org/jira/browse/GOBBLIN-1562
Project: Apache Gobblin
Issue Type: Bug
Components: gobblin-service
Reporter: Kip Kohn
Assignee: Abhishek Tiwari
Current topology spec storage uses the `FSSpecStore` implementation, which may
be deployed on NFS for resilience. To enable migration from NFS, we would
switch to the `MySqlSpecStore`, but unfortunately that class essentially
presumes to store only `FlowSpec`s, and thus would not work for `TopologySpec`s.
Potentially refactor `MysqlSpecStore` into a general backing for any `Spec`
object, without anything specific to `FlowSpec`, so it thus works for topology
specs as well. All the same, continue to retain a specialization with the
existing `FlowSpec`-specific logic, especially around search/retrieval.
Avoid changing/re-naming the semantics of `MysqlSpecStore` to maintain
backwards compatibility for those expecting `FlowSpec` extensions. Therefore,
the refactored `SpecStore` generalization requires a different name.
