AgileData.io - You Know Your Data Best: Override How History Records Are Loaded

When data moves from landing into history, AgileData has to decide what counts as a "new" record. Rows that change over time, such as a customer's status or an account balance, need every version kept, including a value that changes back to an earlier one. Rows that describe something that happened once, such as a transaction, a reading or a video view, should be loaded once and any re-delivery ignored.

AgileData detects which pattern fits by looking at the shape of your data. That works well most of the time, but shape isn't meaning. A table of one-off transactions without typical event column names could be treated as changing data, so re-delivered files would load duplicates. A busy daily snapshot could be treated as events, so a record that reverts to an earlier value would be silently skipped.

You can now set this yourself. The Input Table step of a landing to history rule has a new **Load Type** toggle with three options: **Auto**, which shows what was detected, **Change** and **Event**.

**What's New:**

* Load Type toggle (Auto / Change / Event) on landing to history rules
* Auto mode shows which pattern AgileData has detected, so you can confirm it at a glance
* Removing an override returns the rule to automatic detection on the next save
* Switching the load type on an existing tile marks it for rebuild, so history is regenerated consistently

**What this means for you:**

* No more duplicate rows from re-delivered event files
* No more missed changes when a record returns to an earlier state
* Control over a decision that matters most for history, without needing support to step in
