Bridge Parameters

Parameter Name Description Type Values Default Scope
Root directory Enter the directory containing metadata files or specify it using browsing tool. Bridge provides up to 3 level browsing depth. DIRECTORY     Mandatory
Include filter The include folder and file filter pattern relative to the root directory. #10; The patern uses extended unix glob case-sensitive expression syntax.#10; Here are some common examples:
*.* - include any file at the root level
*.csv - include only csv files at the root level
**.csv -include only csv files at any level
*.{csv,gz} include only csv or gz files at the root level
dir\*.csv - include only csv files in the 'dir' folder
dir\**.csv - include only csv files under 'dir' folder at any level
dir\**.* - include any file under 'dir' folder at any level
f.csv - include only f.csv under root level
**\f.csv - include only f.csv at any level
**dir\** - include all files under any 'dir' folder at any level
**dir1\dir2\** - include all files under any 'dir2' folder under any 'dir1' folder at any level
STRING      
Exclude filter The exclude folder and file filter pattern relative to the root directory. #10; The patern uses the same syntax as the Include filter. See it for the systax details and examples.#10; Files that match the exclude filter are skipped.#10; When both include and exclude filters are empty all folders and files under the Root directory are included. #10; When the include filter is empty and the exclude one is not folders and files under the Root directory are included except ones matching the exclude filter. #10; STRING      
Partition directories Files-based partition directories' paths.
The bridge tries to detect partitions automatically. It can take a long time when partitions have a lot of files.
You can shortcut the detection process for a partition by specifying it in this parameter.
Specify the partition directory path relative to the Root directory.
Use . to specify the root directory as the partitioned directory.

Separate multiple paths with the , (or ;) character.
For example: dir1/dir2,dir3/dir4,dir5
STRING      
Sample size Enter the directory containing metadata files or specify it using browsing tool. Bridge provides up to 3 level browsing depth. NUMERIC      
Incremental import Specifies whether to import only the changes made in the source or to re-import everything (as specified in other parameters).

True - import only the changes made in the source.
False - import everything (as specified in other parameters).

An internal cache is maintained for each metadata source, which contains previously imported models. If this is the first import or if the internal cache has been deleted or corrupted, the bridge will behave as if this parameter is set to 'False'.
BOOLEAN
False
True
True  
Miscellaneous Specify miscellaneous options identified with a -letter and value.

For example, -m 4G -f 100 -j -Dname=value -Xms1G

-m the maximum Java memory size whole number (e.g. -m 4G or -m 2500M ).
-v set environment variable(s) (e.g. -v var1=value -v var2="value with spaces").
-j the last option that is followed by Java command line options (e.g. -j -Dname=value -Xms1G).
-hadoop key1=val1;key2=val2 to manualy set hadoop configuration options
-tps 10 maximum threads pool size
-tl 3600s processing time limit in s -seconds m - minutes or h hours;
-fl 1000 processing files count limit;
STRING
