For the profiles you have configured, you can modify these two settings:
- How many tables should run concurrently during profile run
- For how many profile runs should data in files be available for preview
These rules help you optimize performance based on your requirements and file
size. To specify these settings, perform these steps:
-
In a web browser, go to:
http://server:port/metadata-insights
Where server is the server name or IP address of your
Spectrumâ„¢ Technology Platform server and port is the
HTTP port. By default, the HTTP port is 8080.
-
Log in using your credentials.
-
On the Home page, click
Profiling.
The Profiling page is displayed.
-
Click the Defaults link.
The Profiling Defaults page is
displayed.
-
In the No. of tables for concurrent profiling box,
specify the number of tables that are to be run concurrently for analysis.
Note: This setting is applicable for all the profiles that you set to be run.
The valid range of tables is 1-20, with default value being
5.
Example:
Number of tables for concurrent profiling is
specified as 5 and two profiles, each having six table are set to
run:
Metadata Insights runs five tables
from the profile scheduled to run first and keeps the second profile in
queue (the status is displayed in the Status
field on the Profiles tab of the
Profiling page). Other tables are picked one
after another as profile run completes on the picked-up
tables.
-
In the Keep source data for [N] runs box, specify the
number of runs for which the tables picked up in the profile analysis are saved
in data preview. Default is 2.
Example: Keep source data for [N] runs is set
to 5
Metadata Insights does not show the table data in
preview after five runs are completed for those. If you click the graphs,
bars, or donut charts corresponding to these tables on the Data
Profiling Results page, you will get the message:
Preview is not available. However, the graphs, bars and
donut charts are displayed irrespective of the runs specified in this
field.
