+## Type compatibility
+
+Flink and Iceberg support different set of types. Iceberg does the type
conversion automatically, but not for all combinations,
+so you may want to understand the type conversion in Iceberg in prior to
design the types of columns in your tables.
+
+### Flink type to Iceberg type
+
+This type conversion table describes how Spark types are converted to the
Iceberg types. The conversion applies on both creating Iceberg table and
writing to Iceberg table via Spark.
