Hi, I'm moving to Solr Cloud 6.x and I see rollback cannot be supported when is in Cloud mode.
In my scenario, there are basically two tasks (full indexing, partial indexing). Full indexing ========= This is the most important case, where I really need the possibility to rollback. The full reindex is basically done in 3 steps: 1. delete *:* all collection's documents 2. add all existing documents 3. commit If during the step 2 something go wrong (usually some problem with the source of data) I had to rollback. Partial reindexing ============= Unlike the the former, this case is executed in only 2 steps (no delete) and the number of documents indexed usually is small (or very small). Even in this case if the step 2 go wrong I had to rollback. Do you know if there is a common pattern, a best practice, something of useful to handle a rollback if something go wrong in these cases? My simplistic idea is to have two collections (active/passive), and switch from one to another only when all the steps are completed successfully. But, as you can understand, having two collections works well with full indexing, but how do I handle a partial reindexing if something goes wrong? So, I'll be grateful to whom would spend his/her time to give me a suggestion. Thanks in advance and best regards, Vincenzo -- Vincenzo D'Amore email: v.dam...@gmail.com skype: free.dev mobile: +39 349 8513251
