Database summary diff reporting tool
Diffport is a database summary diff reporting tool. It helps in maintaining, diffing and reporting summaries from a database based on a set of watchers. It currently works (and is tested) under postgres.
Diffport works by using a set of watchers to take snapshots of database at different times and then producing a difference report when asked for it. It uses a config file specifying these watchers and their own specific configuration needs. An example follows:
# diffport.yaml - name: number-of-rows config: groupby: - <groupby-column-one> - <groupby-column-two> table: <table-name> - name: tables-in-schema config: - <schema-one> - <schema-two>
The first watcher (number-of-rows) keeps the count of rows in table <table-name, grouped by columns <groupby-column-one> and <groupby-column-two>. The second watcher tables-in-schema keeps the list of tables in each of the schema provided in its config.
