![]() ![]() It is an important feature provided by jsonb and cannot be done using JSON.Ĥ. Another feature is the provision of Existence Operator in jsonb which checks the existence of top-level keys in JSONB. It allows the testing of Containment, which checks whether one document is contained in another document or not with the help of operator. Besides the efficiency of data performance, Jsonb also provides the benefit of GIN (Generalised Inverted Index). So in case when there is a need only to ingest too much data, JSON data type would work great.ģ. ![]() If we talk about the ingesting speed and processing speed, it is obvious that the ingesting data using jsonb would be somewhat slower as the data is stored in the binary format (so it will be processed first before getting stored) but the further processing of jsonb data is quite faster as compared to JSON. One simple difference between JSON and jsonb data type is that JSON stores the exact copy of the data represented/ inputted in the JSON format to the user whereas jsonb stores the data in the binary format which means that the input data is first processed and then stored in the binary form.Ģ. Some of the key differences between JSON and jsonb explaining the detailed differences between the two are given below:ġ. Key Differences of PostgreSQL JSON vs JSONNB The input function of jsonb is stricter than the JSON as it does not allow the unicode escapes for non-ASCII characters if the database encoding of UTF8 is not set. Unicode escapes are allowed in the JSON input function regardless of the data encoding. In case of a duplicate, only the last key/value pair is preserved. ![]() Jsonb does not preserve duplicate object keys. In JSON, if there exists more than one key for the given value, all the key/value pairs are preserved. Jsonb supports indexing to search for the keys or key/ value pairs which is a great advantage at a bigger database jsonb documents. JSON does not support indexing, unlike jsonb. In the case of jsonb, it is comparatively faster to process the data as no reparsing is needed. Processing function needs to be reparsed in each execution when the input text is in JSON data type. More disk space is required for jsonb data as compared to JSON data type. JSON data does not take much disk space as the JSON data is stored as it is. Schema designs are comparatively easier than Json as it replaces the entity- attribute value with jsonb blob columns which are easier to query. All the entities, attributes, values remain the same. There is no change in the Schema design while working with JSON. Jsonb converts the JSON data into the binary form so it has slightly slower input due to the binary conversion overhead. Json processes input faster than jsonb as there is no conversion involved in this. Jsonb does not preserve the original formatting of text like the whitespaces and the ordering of keys. Json preserves the original formatting like the whitespaces as well as the ordering of keys. Basically, it stores the data in binary form which is not an ASCII/ UTF-8 string. JSON data type stores the exact copy of input text in JSON. ![]()
