# Building Cassandra Storage Engine for Packaging

{% hint style="info" %}
The Cassandra storage engine was removed in MariaDB 10.6.
{% endhint %}

These are instructions on how exactly we build Cassandra SE packages.

## Getting into build environment

See How\_to\_access\_buildbot\_VMs page on the internal wiki. The build VM to use is

```
ezvm  precise-amd64-build
```

Get into the VM and continue to next section.

## Set up Thrift

```
mkdir build
cd build
wget https://dist.apache.org/repos/dist/release/thrift/0.8.0/thrift-0.8.0.tar.gz

sudo apt-get install bzr
sudo apt-get install flex

tar zxvf thrift-0.8.0.tar.gz 
cd thrift-0.8.0/

./configure --prefix=/home/buildbot/build/thrift-inst --without-qt4 --without-c_glib --without-csharp --without-java --without-erlang --without-python --without-perl --without-php --without-php_extension --without-ruby --without-haskell --without-go --without-d
make
make install

# free some space
make clean
cd ..
```

## Get the bzr checkout

* Create another SSH connection to terrier, run the script suggested by motd.
* Press (C-a C-c) to create another window
* Copy the base bazaar repository into the VM:

```
scp /home/psergey/5.5-cassandra-base.tgz runvm:
```

Then, get back to the window with VM, and run in VM:

```
tar zxvf ../5.5-cassandra-base.tgz
rm -rf ../5.5-cassandra-base.tgz
cd 5.5-cassandra/
bzr pull lp:~maria-captains/maria/5.5-cassandra
```

## Compile

```
export LIBS="-lthrift"
export LDFLAGS=-L/home/buildbot/build/thrift-inst/lib

mkdir mkdist
cd mkdist
cmake ..
make dist
```

```
basename mariadb-*.tar.gz .tar.gz > ../distdirname.txt

cp mariadb-5.5.25.tar.gz ../
cd ..
tar zxf "mariadb-5.5.25.tar.gz"
mv "mariadb-5.5.25" build
cd build
mkdir mkbin
cd mkbin
cmake -DBUILD_CONFIG=mysql_release ..
make -j4 package
```

This should end with:

```
CPack: - package: /home/buildbot/build/5.5-cassandra/build/mkbin/mariadb-5.5.25-linux-x86_64.tar.gz generated.
```

Free up some disk space:

```
rm -fr ../../mkdist/
```

```
mv mariadb-5.5.25-linux-x86_64.tar.gz ../..
cd ../..
rm -rf build
```

## Patch the tarball to include Thrift

```
mkdir fix-package
cd fix-package
tar zxvf ../mariadb-5.5.25-linux-x86_64.tar.gz
```

Verify that mysqld was built with Cassandra SE:

```
ldd mariadb-5.5.25-linux-x86_64/bin/mysqld
```

This should point to libthrift-0.8.0.so.

```
cp /home/buildbot/build/thrift-inst/lib/libthrift* mariadb-5.5.25-linux-x86_64/lib/
tar czf mariadb-5.5.25-linux-x86_64.tar.gz mariadb-5.5.25-linux-x86_64/
cp mariadb-5.5.25-linux-x86_64.tar.gz ..
```

## Copy the data out of VM

In the second window (the one that's on terrier, but not in VM), run:

```
mkdir build-cassandra
cd build-cassandra
scp runvm:/home/buildbot/build/5.5-cassandra/mariadb-5.5.25.tar.gz .
scp runvm:/home/buildbot/build/5.5-cassandra/mariadb-5.5.25-linux-x86_64.tar.gz .
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://mariadb.com/docs/server/server-usage/storage-engines/legacy-storage-engines/cassandra/building-cassandra-storage-engine-for-packaging.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
