YugabyteDB Engineering & Community Update – July 19, 2019

VP Developer Relations

July 19, 2019

We are pleased to announce that YugabyteDB 1.3.0 is live! You can read the release notes of this and previous versions here. This release is shipping with 24 new features, enhancements and bug fixes. Beyond enhancements and fixes, the other big news is that we have open sourced the entire core database code! This means that previously closed features like distributed backups, data encryption and replicas are now open sourced. This also means that upcoming features like change data capture and 2 datacenter deployments will open source as well. You can read more about why we decided to make this licensing change by checking out “Why we changed YugabyteDB licensing to 100% open source.”

This release also brings us closer to our 2.0 release at the end of the Summer in which the YSQL API will become generally available.

What’s YSQL? It’s YugabyteDB’s PostgreSQL-compatible, distributed SQL API.

To learn more about what’s shipping in the 2.0 release check out “YugabyteDB 2.0: A Distributed SQL Roadmap.”

Now, let’s highlight a few items in this release:

[#1656] Enable DO statements (a.k.a Anonymous Blocks)

In PostgreSQL, DO statements execute “anonymous code blocks” in any of the supported PostgreSQL procedural languages. The code block itself treated as though it were the body of a function with no parameters, returning void. These anonymous code blocks are parsed and executed just once. One popular way to make use of a DO statement is to rather than create a function, call the function, and then drop (or just ignore) the function that you’ll never need again, it’s easier to simply call a single statement. Here’s a simple test of a DO statement:

do $;
begin
  raise notice 'Hello';
end
$;

NOTICE:  Hello

Thanks to @bllewell for reporting the issue.

[#999] Allow SELECT from sequences
[#1003] Add support for setval()

In a nutshell, the CREATE SEQUENCE command creates a new sequence number generator. This involves creating and initializing a new special single-row table. After a sequence is created, you can use the functions nextval, currval, and setval to operate on the sequence. With the resolution of issue #999, you can now also SELECT from a sequence, for example:

CREATE SEQUENCE test_sequence;

SELECT nextval('test_sequence');

nextval 
---------
       1
(1 row)

SELECT nextval('test_sequence');

 nextval 
---------
       2
(1 row)

SELECT last_value from test_sequence;

 last_value 
------------
          2
(1 row)

With the resolution of issue #1003, setval()is now supported. For example:

SELECT setval('test_sequence', 10);

 setval 
--------
     10
(1 row)

Thanks to @hectorgcr for reporting these two issues.
