+## Writing data with future timestamps
+
+When designing schemas for applications that write data with future timestamps--such as forecast data from machine learning models, predictions, or scheduled events--consider the following implications for InfluxDB Enterprise v1 cluster operations and data integrity.
+
+### Understanding future data behavior
+
+InfluxDB Enterprise v1 creates shards based on time ranges.
+When you write data with future timestamps, InfluxDB creates shards that cover future time periods.

+
+### Use separate databases for future data
+
+When planning for data that contains future timestamps, consider isolating it in dedicated databases to:
+
+- Minimize impact on real-time data operations
+- Allow targeted maintenance operations on current vs. future data
+- Simplify backup and recovery strategies for different data types
+
+```sql
+# Example: Separate databases for different data types
+CREATE DATABASE "realtime_metrics"
+CREATE DATABASE "ml_forecasts"
+CREATE DATABASE "scheduled_predictions"
+```

+
+When you write data points with timestamps in the future (for example, forecast data from machine learning models),
+the `truncate-shards` command behaves differently and can cause data duplication issues.
+
+### How truncate-shards normally works
+
+For shards containing current data:
+1. The command creates an artificial stop point in the shard at the truncation timestamp
+2. Creates a new shard starting from the truncation point
+3. Example: A one-week shard (Sunday to Saturday) becomes:
+   - Shard A: Sunday to truncation point (Wednesday 2pm)
+   - Shard B: Truncation point (Wednesday 2pm) to Saturday
+   
+This works correctly because the meta nodes understand the boundaries and route queries appropriately.
+
+### The problem with future data
+
+For shards containing future timestamps:
+1. The truncation doesn't cleanly split the shard at a point in time
+2. Instead, it creates overlapping shards that cover the same time period
+3. Example: If you're writing September forecast data in August:
+   - Original shard: September 1-7
+   - After truncation: 
+     - Shard A: September 1-7 (with data up to truncation)
+     - Shard B: September 1-7 (for new data after truncation)
+   - **Result**: Duplicate data points for the same timestamps
