Snuba SDK for generating SnQL queries.
Project description

Examples
Snuba SDK is a tool that allows requests to Snuba to be built programatically. A Request consists of a Query, the dataset the Query is targeting, the AppID of the Request, and any flags for the Request. A Query object is a code representation of a SnQL or MQL query, and has a number of attributes corresponding to different parts of the query.
Requests and Queries can be created directly:
request = Request(
dataset = "discover",
app_id = "myappid",
tenant_ids = {"referrer": "my_referrer", "organization_id": 1234}
query = Query(
match=Entity("events"),
select=[
Column("title"),
Function("uniq", [Column("event_id")], "uniq_events"),
],
groupby=[Column("title")],
where=[
Condition(Column("timestamp"), Op.GT, datetime.datetime(2021, 1, 1)),
Condition(Column("project_id"), Op.IN, Function("tuple", [1, 2, 3])),
],
limit=Limit(10),
offset=Offset(0),
granularity=Granularity(3600),
),
flags = Flags(debug=True)
)Queries can also be built incrementally:
query = (
Query("discover", Entity("events"))
.set_select(
[Column("title"), Function("uniq", [Column("event_id")], "uniq_events")]
)
.set_groupby([Column("title")])
.set_where(
[
Condition(Column("timestamp"), Op.GT, datetime.datetime.(2021, 1, 1)),
Condition(Column("project_id"), Op.IN, Function("tuple", [1, 2, 3])),
]
)
.set_limit(10)
.set_offset(0)
.set_granularity(3600)
)Once the request is built, it can be translated into a Snuba request that can be sent to Snuba.
# Outputs a formatted Snuba request
request.serialize()It can also be printed in a more human readable format.
# Outputs a formatted Snuba request
print(request.print())This outputs:
{
"dataset": "discover",
"app_id": "myappid",
"query": "MATCH (events) SELECT title, uniq(event_id) AS uniq_events BY title WHERE timestamp > toDateTime('2021-01-01T00:00:00.000000') AND project_id IN tuple(1, 2, 3) LIMIT 10 OFFSET 0 GRANULARITY 3600",
"debug": true
}If an expression in the query is invalid (e.g. Column(1)) then an InvalidExpressionError exception will be thrown. If there is a problem with a query, it will throw an InvalidQueryError exception when .validate() or .translate() is called. If there is a problem with the Request or the Flags, an InvalidRequestError or InvalidFlagError will be thrown respectively.
MQL Examples
MQL queries can be built in a similar way to SnQL queries. However they use a MetricsQuery object instead of a Query object. The query argument of a MetricsQuery is either a Timeseries or Formula, which is a mathemtical formula of Timeseries.
The other arguments to the MetricsQuery are meta data about how to run the query, e.g. start/end timestamps, the granularity, limits etc.
MetricsQuery(
query=Formula(
ArithmeticOperator.DIVIDE.value,
[
Timeseries(
metric=Metric(
public_name="transaction.duration",
),
aggregate="sum",
),
1000,
],
),
start=NOW,
end=NOW + timedelta(days=14),
rollup=Rollup(interval=3600, totals=None, granularity=3600),
scope=MetricsScope(
org_ids=[1], project_ids=[11], use_case_id="transactions"
),
limit=Limit(100),
offset=Offset(5),
