This is part of a series of blogs on Java & PostgreSQL. For links to other blogs in this series, please scroll to the end of this post.Starting v9.2, PostgreSQL is providing native data type support for JSON objects. Subsequent releases introduced JSONB (binary formatted JSON objects) and many data manipulation functions for JSONs, making it a very powerful tool for NoSQL operations. String manipulation and parsing are very expensive operations in a database, so although you could have potentially stored JSON objects in strings in PostgreSQL before, introduction of the native data type has taken away overheads and made throughput a lot faster for JSON manipulation.JSON & JSONB JSONB was introduced as a native data type in v9.4 of PostgreSQL and it stores JSON objects...
The `jsonb_insert` function brought in with PostgreSQL 9.6 gives more control when inserting new values into a jsonb array and/or new keys into a jsonb object. This article introduces this new function together with some examples. (more…)
PostgreSQL 9.5 has introduced new JSONB functionalities, greatly improving its already present NoSQL characteristics. With the inclusion of new operators and functions, now it is possible to easily modify the JSONB data. In this article these new modifiers will be presented together with some examples of how to use them. (more…)
The 9.4 version of PostgreSQL introduces the JSONB data type, a specialised representation of the JSON data, allowing PostgreSQL to be competitive in managing the “lingua franca” of the moment for the exchange of data via web services. It is useful to perform a number of tests to verify its actual performance. (more…)
The introduction of the JSONB data type in PostgreSQL, definitely makes the “NoSQ” side of this relational DBMS come out: this introduction meets the requirements of all those who prefer a data structure in a “key-value” array, dictionary style (widely used in the field of development) and, at the same time, ensures all the advantages of a relational database.(more…)
