The JSON data type can be stored in binary format (BSON). Specify BSON with the optional STORAGE FORMAT clause in the data type specification syntax.
BSON data can be stored inline (inside a row) or outside the row in a LOB subtable or both, depending on the syntax used to specify it:
| Syntax | Default Inline Storage | Maximum Length | LOB/Non-LOB |
|---|---|---|---|
| JSON(n) STORAGE FORMAT BSON, where n <= 64,000 | n bytes | n bytes | Non-LOB |
| JSON(n) STORAGE FORMAT BSON, where n > 64,000 | 4,096 bytes | n bytes | LOB |
| JSON(n) STORAGE FORMAT BSON INLINE LENGTH m | m bytes | n bytes | If n <= m, Non-LOB Otherwise, LOB |
If there is no column length specified, the default length is the maximum. The BSON type has a maximum total size of 16 MB (16,776,192 bytes).
The maximum size for BSON reflects the number of bytes in the data. This is different than the case for JSON text, where the maximum size reflects the number of characters in the data.
