When should we use JSONB?
9 Answers
- jsonb usually takes more disk space to store than json (sometimes not)
- jsonb takes more time to build from its input representation than json.
- json operations take significantly more time than jsonb (& parsing also needs to be done each time you do some operation at a json typed value)
What is a JSONB column?
The JSONB data type stores JSON (JavaScript Object Notation) data as a binary representation of the JSONB value, which eliminates whitespace, duplicate keys, and key ordering. JSONB supports inverted indexes. For a hands-on demonstration of storing and querying JSON data from a third-party API, see the JSON tutorial.
How is Jsonb stored?
The data types json and jsonb , as defined by the PostgreSQL documentation,are almost identical; the key difference is that json data is stored as an exact copy of the JSON input text, whereas jsonb stores data in a decomposed binary form; that is, not as an ASCII/UTF-8 string, but as binary code.
When to use JSONB or jsob data types?
If you know before hand that you will not be performing JSON querying operations, then use the JSON data type. For all other cases, use JSONB. The following example demonstrates the difference: (the whitespace and the order of the keys are preserved in the JSOB column.)
What is difference between JSON and JSONB in PostgreSQL?
Notably, jsonb will reject numbers that are outside the range of the PostgreSQL numeric data type, while json will not. Such implementation-defined restrictions are permitted by RFC 7159.
When to use JSONB vs JSON blob?
JSONB on the other hand stores JSON data in a custom format that is optimized for querying and will not reparse the JSON blob each time. If you know before hand that you will not be performing JSON querying operations, then use the JSON data type. For all other cases, use JSONB. The following example demonstrates the difference:
Which is the binary form of JSON data?
As we mentioned above, the JSONB data type is the binary form of the JSON data type. The two data types used for storing JSON data come with a number of handy built-in functions that make it easy to query and manipulate data.
