It is possible using LSI/GSI.
See the boto tutorial here (search for LSI, and you will get the example). DynamoDB2 — boto v2.25.0 : http://boto.readthedocs.org/en/latest/ref/dynamodb2.html
Adding a full working example (tried with dynamo local: http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Tools.DynamoDBLocal.html)
conn = DynamoDBConnection(
host='localhost',
port=8000,
aws_access_key_id='DEVDB', #anything will do
aws_secret_access_key='DEVDB', #anything will do
is_secure=False)
tables = conn.list_tables()
print "Before Creation:", tables
table_name = 'myTable'
if table_name not in tables['TableNames']:
Table.create(table_name
, schema=[HashKey('firstKey')]
, throughput={'read': 5, 'write': 2}
, global_indexes=[
GlobalAllIndex('secondKeyIndex', parts=[HashKey('secondKey')], throughput={'read': 5, 'write': 3})]
, connection=conn
)
#print_table_details(conn, table_name)
table = Table(table_name, connection=conn)
item = Item(table, data={
'firstKey': str(uuid.uuid4()),
'secondKey': 'DUMMY-second'
})
item.save()
results = table.query(secondKey__eq='DUMMY-second', index='secondKeyIndex')
for res in results:
print res['firstKey'], res['secondKey']
The result of execution is:
91d4d056-1da3-42c6-801e-5b8e9c42a93f DUMMY-second
15c17b09-4975-419a-b603-427e4c765f03 DUMMY-second
dd947b7d-935e-458f-84d3-ed6cd4f32f5a DUMMY-second
Also adding the exact packages (Due to Dynamo1/2 - there is chance of mistake):
from boto.dynamodb2.fields import HashKey, RangeKey, GlobalAllIndex
from boto.dynamodb2.layer1 import DynamoDBConnection
from boto.dynamodb2.table import Table
from boto.dynamodb2.items import Item
