IMPORTING FROM FILESYSTEM

This bridge is loading metadata from FileSystem files.
Bridge supports following compressed formats:

Please refer to the individual parameter's tool tips for more detailed examples.


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 Relative to the root path, case sensitive filter of files expressed using the extended unix glob expression pattern syntax (e.g. '/*.csv' - import files that end with .csv in root folder; **.csv - import all .csv files in any directory level).
STRING      
Exclude filter Similar to the include filter parameter 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 ; characters.
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      
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 ).
-s import system objects that are skipped by default (e.g. -s)
-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
STRING      
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
