Re: [discovery] [Ops] Index management for Maps

Hello! I need some feedback from my fellow Ops on how to manage indexes on Maps. Context: Maps imports OpenStreetMap data in a Postgresql database. This import is done with osm2pgsql, which takes care of creating the schema, populating tables and creating a few indexes. Some additional indexes are required to support the specific functionalities of Tilerator. So far, those indexes have been created manually and have not been tracked. The enhancements to the schema created by osm2pgsql are minor (a few index and functions), so we probably need a lightweight solution. Proposal: A few idempotent scripts are versionned in osm-bright.tm2source [1]. Those scripts are executed after review by Ops, at the request of the project. We don't use a full schema migration process, because at this point there isn't really a need for it on this project. Does this look reasonable to you? Feedback welcomed, shoot me down if you have to...
