Simon Prévost explains a method to optimize batch operations with Ecto in an Elixir application. The article describes the initial problem of handling numerous SQL operations triggered by user actions and details a solution that consolidates multiple SQL queries into one. This involves steps such as optimizing `INSERT` operations to handle multiple records in a single query, optimizing `UPDATE` queries, and handling dynamic updates efficiently using PostgreSQL `unnest` syntax. The article highlights the advantages of separating operation evaluation from SQL execution, allowing efficient batching of SQL statements. The complete code is available in a linked pull request.
