Wildcard characters

When you read data from an Avro, flat, JSON, ORC, or Parquet file, you can use wildcard characters to specify the source file name.

To use wildcard characters for the source file name, select the source type as Directory
and enable the

Allow Wildcard Characters

option in the advanced source properties.

When you read an Avro, JSON, ORC, Parquet, or flat file, you can use the

and

wildcard characters to define one or more characters in a search.

You can use the following wildcard characters:

? (Question mark): The question mark character (?) allows one occurrence of any character. For example, if you enter the source file name as
a?b.txt
, the Secure Agent reads data from files with the following names:
a1b.txt

a2b.txt

aab.txt

acb.txt
* (Asterisk): The asterisk mark character (*) allows zero or more than one occurrence of any character. If you enter the source file name as
a*b.txt
, the Secure Agent reads data from files with the following names:
aab.txt

a1b.txt

ab.txt

abc11b.txt
