OSS Delta > Schema Evolution Tutorial Update #336
Comments
Thanks for the recommendations! I agree that we should make the blog post more detailed. Open to PRs here. I don't think we should merge the code snippets into a large code block. Readers generally don't like that because it makes the post harder to parse. |

In this issue, we will perform 2 updates:
1. Adding supported and unsupported use cases to the schema evolution tutorial for OSS Delta;
2. Merging individual code blocks, to enable 1-click replication of schema evolution example.
1. Adding supported and unsupported use cases to the schema evolution tutorial for OSS Delta;
If you scroll right all the way till before "How is Schema Evolution Useful" https://www.databricks.com/blog/2019/09/24/diving-into-delta-lake-schema-enforcement-evolution.html, you will see the (un)supported use cases. Of course, this is for Databricks, and perhaps you need to check with engineers whether it is the same for OSS Delta, just to err on the side of caution.
2. A personal stylistic preference: when we're illustrating one example, merge all the code blocks into one, and change the comments to in line comments. So that users only need to copy and paste 1 time to replicate your example. For example, I would put all of these into 1 block, interlace it with your comments.
