Honeycomb is an open source MySQL storage engine which stores tables into an external data store, or backend. Honeycomb currently supports storing tables to HBase and an in-memory store. See the project page for more details.

System Requirements

The following system requirements must be installed and configured for Honeycomb execution:

• Oracle Java 6
• Hadoop
  • Apache 1.0+ or CDH 4.3+
• HBase
  • Apache 0.94.3+ or CDH 4.3+

Getting Started

• Build from source
• Install pre-built binaries (below)

Install MySQL and Honeycomb from pre-built Linux binaries

These binaries have been tested with CentOS 6.4 and Ubuntu 13.04

1. Export the 'JAVA_HOME' environment variable to refer to the location of Java on your system
2. Download the Honeycomb Linux 64-bit tarball
3. Run tar xzf mysql-5.5.31-honeycomb-0.1-linux-64bit.tar.gz
4. Change directory to mysql-5.5.31-honeycomb-0.1

or, run the following in a shell:

curl -O https://s3.amazonaws.com/Honeycomb/releases/mysql-5.5.31-honeycomb-0.1-linux-64bit.tar.gz
tar xzf mysql-5.5.31-honeycomb-0.1-linux-64bit.tar.gz
cd mysql-5.5.31-honeycomb-0.1

Configure Honeycomb

Honeycomb reads its application configuration from the file honeycomb.xml that is located in the top level of the install binary.

• If using the HBase backend, add the following to each file hbase-site.xml on each HBase region server and restart the region servers:

  <property>
    <name>hbase.coprocessor.region.classes</name>
    <value>org.apache.hadoop.hbase.coprocessor.example.BulkDeleteEndpoint</value>
  </property>

• If connecting to a remote HBase cluster, change the value of the tag hbase.zookeeper.quorum in the HBase backend configuration section of honeycomb.xml to the quorum location.
• If you want to use the in-memory backend, change the value of the element defaultAdapter in honeycomb.xml to memory.

For more information on application configuration, refer to the configuration page.

Start MySQL

5. Execute run-mysql-with-honeycomb-installed.sh
6. Execute bin/mysql -u root --socket=mysql.sock

or,

./run-mysql-with-honeycomb-installed.sh
bin/mysql -u root --socket=mysql.sock --port=5630

Once Honeycomb is up and running, test it with:

create table foo (x int, y varchar(20)) character set utf8 collate utf8_bin engine=honeycomb;
insert into foo values (1, 'Testing Honeycomb');
select * from foo;
