Returns the Query execution chart.
Parameters#
- node_name: str | list, optional
Node(s) name(s). It can be a simple node
str
or alist
of nodes. If empty, all the nodes are used.- metric: str, optional
Metric to use. One of the following: - all (all metrics are used). - exec_time_ms (default) - est_rows - proc_rows - prod_rows - rle_prod_rows - clock_time_us - cstall_us - pstall_us - mem_res_mb - mem_all_mb
- path_id: str
Path ID.
- kind: str, optional
Chart Type.
- bar:
Drilldown Bar Chart.
- barh:
Horizontal Drilldown Bar Chart.
- pie:
Pie Chart.
- multi: bool, optional
If set to
True
, a multi variable chart is drawn by using ‘operator_name’ and ‘path_id’. Otherwise, a single plot using ‘operator_name’ is drawn.- categoryorder: str, optional
How to sort the bars. One of the following options:
trace (no transformation)
category ascending
category descending
total ascending
total descending
min ascending
min descending
max ascending
max descending
sum ascending
sum descending
mean ascending
mean descending
median ascending
median descending
- rows: int, optional
Only used when
metric='all'
. Number of rows of the subplot.- cols: int, optional
Only used when
metric='all'
. Number of columns of the subplot.- show: bool, optional
If set to
True
, the Plotting object is returned.- **style_kwargs
Any optional parameter to pass to the plotting functions.
Returns#
- obj
Plotting Object.
Examples#
First, let’s import the
QueryProfiler
object.from verticapy.performance.vertica import QueryProfiler
Then we can create a query:
qprof = QueryProfiler( "select transaction_id, statement_id, request, request_duration" " from query_requests where start_timestamp > now() - interval'1 hour'" " order by request_duration desc limit 10;" )
To get node-wise performance information,
get_qexecution
can be used:qprof.get_qexecution()
Note
To use one specific node:
qprof.get_qexecution( node_name = "v_vdash_node0003", metric = "exec_time_ms", kind = "pie", )
To use multiple nodes:
qprof.get_qexecution( node_name = [ "v_vdash_node0001", "v_vdash_node0003", ], metric = "exec_time_ms", kind = "pie", )
The node name is different for different configurations. You can search for the node names in the full report.
Note
For more details, please look at
