Now that the
source tree for the new
Falcon Storage Engine is finally public, here's a quick HOWTO on how to compile the server from source. This procedure is described in more detail in the
MySQL Manual. I assume you use Linux and have the required development toolchain installed.
You first should get the free BK client from http://www.bitmover.com/bk-client2.0.shar, unpack and install it:
$ wget http://www.bitmover.com/bk-client2.0.shar
--17:34:34-- http://www.bitmover.com/bk-client2.0.shar
=> `bk-client2.0.shar'

$ sh ./bk-client2.0.shar

x - creating directory bk-client2.0

x - extracting bk-client2.0/demo.sh (text)
$ cd bk-client2.0
$ make
cc -O2 -Wall -Wno-parentheses bkf.c -o bkf
$ sudo install -m755 bkf /usr/local/bin
Now that the BK client is installed, we can create a local clone of the Falcon development tree:
$ bkf clone bk://mysql.bkbits.net/mysql-5.2-falcon mysql-5.2-falcon
This will now perform a check out the most recent source tree from the mysql-5.2-falcon repository (~83 MB of source code). You can now enter the newly created directory and start the build:
$ cd mysql-5.2-falcon
$ ./BUILD/compile-pentium-debug-falcon
If you have a x86_64 Linux system, use
compile-amd64-debug-falcon instead. Depending on the performance of your system, this step will take a while, as it performs a full compile of the MySQL server and all related tools. Once the build completed with no errors, you can create a binary tarball distribution:
./scripts/make_binary_distribution
This should leave you with a tarball
mysql-5.2.0-falcon-alpha-linux-i686.tar.gz that you can now install to, say,
/usr/local:
$ tar zxvf mysql-5.2.0-falcon-alpha-linux-i686.tar.gz -C /usr/local
$ cd /usr/local
$ ln -s mysql-5.2.0-falcon-alpha-linux-i686 mysql
$ cd mysql
$ ./configure
The last command will install the privilege tables and start up the mysql server. You can now fire up the mysql client:
$ ./bin/mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.2.0-falcon-alpha-debug
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
Now make sure that falcon has indeed been included:
mysql> SHOW VARIABLES LIKE 'have_falcon';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| have_falcon | YES |
+---------------+-------+
1 row in set (0.01 sec)
Looks good! Now it's time to actually
create a table that uses the Falcon engine:
mysql> use test;
Database changed
mysql> CREATE TABLE names (id INT, fname VARCHAR (20), lname VARCHAR (20)) ENGINE=Falcon;
Query OK, 0 rows affected (2.84 sec)
mysql> describe names;
+-------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+-------+
| id | int(11) | YES | | NULL | |
| fname | varchar(20) | YES | | NULL | |
| lname | varchar(20) | YES | | NULL | |
+-------+-------------+------+-----+---------+-------+
3 rows in set (0.01 sec)
mysql> INSERT INTO names VALUES (0, 'Lenz', 'Grimmer');
Query OK, 1 row affected (0.03 sec)
mysql> INSERT INTO names VALUES (1, 'Monty', 'Widenius');
Query OK, 1 row affected (0.06 sec)
mysql> SELECT * FROM names WHERE lname='Widenius';
+------+-------+----------+
| id | fname | lname |
+------+-------+----------+
| 1 | Monty | Widenius |
+------+-------+----------+
1 row in set (0.00 sec)
Congratulations, you are ready to further test and explore this new storage engine! Have fun with testing it - we would appreciate your feedback and experiences! Please share your impressions via the
Falcon Forum or
report bugs via our Bug Database. Make sure to read the
bug reporting guidelines on the MySQL Forge Wiki first!
UPDATE: The people at Bitkeeper updated the free BK client to version 2.0 after I wrote this. I updated the described procedure above accordingly. Currently, the repository seems to have a locking problem that only appears when using the free BK client. We are working with the BitKeeper team on resolving this issue.
