Hello,
I want to show euros values on dashboard. But only the $ format are enable. When i changed the $ symbol to € i obtained an error.
How can I show euros value in a chart ?

I want something like "y_axis_format": "$,.2f" ==> to "y_axis_format": ",.2f€"

Regards,
Zied Sellami

Current behavior

All ShellTask logs are logged at DEBUG level, preventing showing the command output in the UI logs unless the agent's logging threshold is set to DEBUG. But this is undesired for production workloads, as this applies to all log messages

streaming logging for the ShellTask was introduced in #3584

Proposed behavior

change existing stream_logs parameter to `U

Describe the bug
bare decimals in arithmetic in evaluation parameters cause a parsing error

To Reproduce
Steps to reproduce the behavior:

1. Write an expectation with an evaluation parameter that...
2. has a urn and some simple arithmetic with...
3. a bare decimal value
4. execute the expectation and note the parsing failure

downstream_batch.expect_column_mean_to_b

Problem description

When I use the function of concatenating multiple columns, I find that it does not handle null values as expected.

This is the current output

df.concatenate_columns(["cat_1","cat_2","cat_3"],"cat",sep=",")

if they are not class methods then the method would be invoked for every test and a session would be created for each of those tests.

@classmethod
def suppress_py4j_logging(cls):
logger = logging.getLogger('py4j')
logger.setLevel(logging.WARN)
