Changelog

This page details new additions to the stream processor engine in major release versions of Fluent Bit.

Fluent Bit v1.2

Release date: June 27, 2019

Sub-key selection and conditionals support

Added the ability to use nested maps and sub-keys to perform conditions and key selections. For example, consider the following record:

{
  "key1": 123,
  "key2": 456,
  "key3": {
    "sub1": {
      "sub2": 789
    }
  }
}

Now you can perform queries like:

SELECT key3['sub1']['sub2'] FROM STREAM:test WHERE key3['sub1']['sub2'] = 789;

New @record functions

For conditionals, added the new @record functions:

Function	Description
@record.time()	Returns the record timestamp.
@record.contains(key)	Returns true or false if key exists in the record, or false if not.

IS NULL and IS NOT NULL

Added IS NULL and IS NOT NULL statements to determine whether an existing key in a record has a null value. For example:

SELECT * FROM STREAM:test WHERE key3['sub1'] IS NOT NULL;

For more details, see Check keys and null values.
