Enable File Placeholders

Enables usage of placeholder files. The placeholder file serves to save your disk space and to speed up synchronization in server projects. The files with a size above the specified limit are replaced with placeholder files (in Designer).

Usually, you do not need to see the content of these files and you do not commit them into repository. See CloverETL Server Project.

Default: enabled

Placeholder Size Threshold

Files above this threshold are replaced with placeholder files. The size is in MB.

Default: 10

Synchronization Threads Limit

The maximum number of threads used for synchronization between CloverETL Designer and CloverETL Server. Using more threads can speed up synchronization in networks with high latency.

Default: 10

Synchronization Cache Size

While downloading files from CloverETL Server during synchronization, the content of files is cached in memory to improve the performance. This parameter sets the cache size.

Default: 30

Request Timeout

A request timeout of connection to CloverETL Server. The request timeout is in seconds.

Default: 30

Connect Timeout

Timeout of the connection to CloverETL Server. The timeout is in seconds.

Default: 30

Sandbox cache validity

Validity of sandbox cache. In seconds. Used for performance tuning in old (RSE) projects.

Default: 10

File info cache validity

Validity of file info cache. In seconds. Used for performance tuning in old (RSE) projects.

Default: 10

File content cache validity

Validity of file content cache. In seconds. Used for performance tuning in old (RSE) projects.

Default: 10

Close server connection after each request

Enables closing connection to the server after each request. Used for performance tuning in old (RSE) projects.

Default: false

Restoring Default Values

Use Restore Defaults to reset the values.

Restart CloverETL Designer to use new timeout values.
