INSERT INTO ... JSON syntax introduced in
Cassandra 2.2.
With INSERT statements, the new JSON keyword can be used to enable inserting a JSON
structure as a single row.
The provided object can be of the following types:
SELECT JSON statement on the same table. Note that it is not
possible to insert function calls nor bind markers in a JSON string.
bind marker. In this case, the statement is meant to
be prepared and no JSON string will be appended to the query string, only a bind marker
for the whole JSON parameter.
codec is registered with the CodecRegistry in use. This allows the usage of JSON libraries, such as the Java API for JSON processing, the popular
Jackson library, or Google's Gson library, for instance.
For example, to insert into a table with two columns named “myKey” and “value”, you would do the following:
insertInto("mytable").json("{\"\\\"myKey\\\"\": 0, \"value\": 0}");
This will produce the following CQL:
INSERT INTO mytable JSON '{"\"myKey\"": 0, "value": 0}';
foo"'bar should be inserted in the JSON string as "foo\"''bar".

Support for DEFAULT UNSET has been introduced in Cassandra 3.10.

INSERT statement.using - the option to add.INSERT statement.public Insert.Options using()
INSERT statement.
Chain this with Insert.Options.and(Using) to add options.
INSERT statement.public Insert ifNotExists()
INSERT statement.
An insert with that option will not succeed unless the row does not exist at the time the insertion is executed. The existence check and insertions are done transactionally in the sense that if multiple clients attempt to create a given row with this option, then at most one may succeed.
Please keep in mind that using this option has a non negligible performance impact and should be avoided when possible.
This will configure the statement as non-idempotent, see Statement.isIdempotent() for more information.
