"""
A tool for migrating alarms and alarms history data from NoSQL to SQL.
NOTES:
- Users need to specify the source NoSQL connection url and the destination SQL
connection URL with this tool, an usage example:
aodh-data-migration --nosql-conn \
mongodb://aodh:password@127.0.0.1:27017/aodh --sql-conn \
mysql+pymysql://root:password@127.0.0.1/aodh?charset=utf8
- Both the alarm data and alarm history data will be migrated when running this
tool, but the history data migration can be avoid by specifying False of
--migrate-history option.
- It is better to ensure the db connection is OK when running this tool, and
this tool can be run repeatedly, the duplicated data will be skipped.
- This tool depends on the NoSQL and SQL drivers of Aodh, so it is should be
used only before the removal of NoSQL drivers.
- This tool has been tested OK in devstack environment, but users need to be
cautious with this, because the data migration between storage backends is
a bit dangerous.

Configuration
=============
HBase
===================
This storage implementation uses Thrift HBase interface. The default Thrift
connection settings should be changed to support using ConnectionPool in HBase.
To ensure proper configuration, please add the following lines to the
`hbase-site.xml` configuration file::
<property>
<name>hbase.thrift.minWorkerThreads</name>
<value>200</value>
</property>
For pure development purposes, you can use HBase from Apache_ or some other
vendor like Cloudera or Hortonworks. To verify your installation, you can use
the `list` command in `HBase shell`, to list the tables in your
HBase server, as follows::
$ ${HBASE_HOME}/bin/hbase shell
hbase> list
.. note::
This driver has been tested against HBase 0.94.2/CDH 4.2.0,
HBase 0.94.4/HDP 1.2, HBase 0.94.18/Apache, HBase 0.94.5/Apache,
HBase 0.96.2/Apache and HBase 0.98.0/Apache.
Versions earlier than 0.92.1 are not supported due to feature incompatibility.
To find out more about supported storage backends please take a look on the
:doc:`install/manual/` guide.
.. note::
If you are changing the configuration on the fly to use HBase, as a storage
backend, you will need to restart the Aodh services that use the
database to allow the changes to take affect, i.e. the collector and API
services.

services. You may use one of the listed database backends below to store
Aodh data.
.. note::
Please notice, MongoDB requires pymongo_ to be installed on the system. The
required minimum version of pymongo is 2.4.
..
SQLalchemy-supported DBs
------------------------
The recommended Aodh storage backend is any SQLAlchemy-supported
database (`PostgreSQL` or `MySQL`).
In case of SQL-based database backends, you need to create a `aodh`
database first and then initialise it by running::

To use MySQL as the storage backend, change the 'database' section in

[database]
connection = mysql+pymysql://username:password@host/aodh?charset=utf8
MongoDB
-------
Follow the instructions to install the MongoDB_ package for your operating
system, then start the service. The required minimum version of MongoDB is 2.4.
To use MongoDB as the storage backend, change the 'database' section in
aodh.conf as follows::
[database]
connection = mongodb://username:password@host:27017/aodh
If MongoDB is configured in replica set mode, add `?replicaSet=` in your
connection URL::
[database]
connection = mongodb://username:password@host:27017/aodh?replicaSet=foobar
HBase
-----
HBase backend is implemented to use HBase Thrift interface, therefore it is
mandatory to have the HBase Thrift server installed and running. To start
the Thrift server, please run the following command::
${HBASE_HOME}/bin/hbase thrift start
The implementation uses `HappyBase`_, which is a wrapper library used to
interact with HBase via Thrift protocol. You can verify the thrift
connection by running a quick test from a client::
import happybase
conn = happybase.Connection(host=$hbase-thrift-server, port=9090, table_prefix=None)
print conn.tables() # this returns a list of HBase tables in your HBase server
.. note::
HappyBase version 0.5 or greater is required. Additionally, version 0.7
is not currently supported.
..
In case of HBase, the needed database tables (`project`, `user`, `resource`,
`meter`, `alarm`, `alarm_h`) should be created manually with `f` column
family for each one.
To use HBase as the storage backend, change the 'database' section in
aodh.conf as follows::
[database]
connection = hbase://hbase-thrift-host:9090
