Will any import (by data pump) operation on Oracle Database be captured by GoldenGate Integrated Extract ?

I am working on a project to import data from a Sybase database backup. From my review of Snowflake documentation I see no mention of how one might do this other than writing custom ETL to export data for each table into a supported structured data format (e.g. csv or xml) and then load that file into snowflake.
Is there a way to have Snowflake load schema and data directly from a database backup file? Even if there is a way to do this for some other database vendor (other than Sybase) that might be helpful.
I did CSV file import using SAP IQ LOAD TABLE SQL command which did it in less than a second, but with Interactive SQL import wizard tool it took almost 2+ hours. I am interested to know why it was so much faster. Table has more than 138'000 rows.
The LOAD TABLE statement tells the database server to read the file directly. The import wizard tells the client to read the file and send the data to the server. Depending on the type of connection (shared memory, TCP/IP, encrypted or not, etc.) and the size of the file, the difference can be substantial.
On the subject of importing data into sqoop from Microsoft SQL Server. How does sqoop handle database locks when running import table commmands?
More info:
Sqoop is using a JDBC driver.
Sqoop handles database locks by taking required locks and respecting conflicting locks acquired by other processes. Same as everybody else.
What exactly are you worried about? Sqoop does ordinary INSERT operations.
What is the best way to refresh test data with Production data Automatically ? I am using Oracle database.

I have a fairly large SQL Server database; I'd like to pull 4 tables out and dump them directly into an sqlite.db for remote querying (via nightly batch).
I was about to write a script to step through(most likely on a unix host kicked off via cron); but there should be a simpler method to export the tables directly (SQLite not an option in the included DTS Import/Export wizard)
What would the most efficient method of dumping the SQL Server tables to SQLite via batch be?
You could export your data from ms-sql with sqlcmd to a text file, and later import this with a bulk import in sqlite. Read this question and answers to get an idea how to do this in sqlite.
You could create a batch file and run this with cron, I guess.
If you were considering DTS, then you might be able to do so via ODBC. MSSQL -> ODBC -> Sqlite
