Happybase的基本使用

Happybase是Python通过Thrift访问HBase的库，方便快捷。

基本使用

1. import happybase
3. connection = happybase.Connection('hostname')
4. table = connection.table('table-name')
6. table.put('row-key', {'family:qual1': 'value1', 'family:qual2': 'value2'})
8. row = table.row('row-key')
9. print row['family:qual1'] # prints 'value1'
11. for key, data in table.rows(['row-key-1', 'row-key-2']):
12. print key, data # prints row key and data for each row
14. for key, data in table.scan(row_prefix='row'):
15. print key, data # prints 'value1' and 'value2'
17. row = table.delete('row-key')

链接

1. # lazy connection
2. connection = happybase.Connection('somehost', autoconnect=False)
4. # and before first use:
5. connection.open()
7. # show all tables
8. print connection.tables()
10. # Using table namespace
11. connection = happybase.Connection('somehost', table_prefix='myproject')

表

1. connection.create_table(
2. 'mytable',
3. {'cf1': dict(max_versions=10),
4. 'cf2': dict(max_versions=1, block_cache_enabled=False),
5. 'cf3': dict(), # use defaults
6. }
7. )
9. table = connection.table('mytable')
