Installation
You can install the elasticsearch backend with pip
pip install wallaby-backend-elasticsearchHow to use
The library is based on twisted's asynchronous pattern. To use the library in an asynchronous fassion you first need to create an reactor based application:
from twisted.internet import defer
@defer.inlineCallbacks
def run():
# wait 1 second
d = defer.Deferred()
reactor.callLater(1.0, d.callback)
yield d
# stop the reactor and quit the application
reactor.stop()
from twisted.internet import reactor
reactor.callWhenRunning(run)
reactor.run()Now we can connect to an existing elasticsearch cluster:
@defer.inlineCallbacks
def run():
# Create elasticsearch client object
from wallaby.backends.elasticsearch import Connection
es = Connection(
baseURL="http://localhost:9200",
index="<name of index>",
username="<username>",
password="<password>",
)
# Send query
res = yield es.doQuery({
"query": {
"query_string": {
"query": "*"
}
}
})
# stop the reactor and quit the application
reactor.stop()
