FME特性存储(FFS)作家参数

If checked, Create Index creates and outputs a spatial index for each feature store.The spatial index has the same base name as the FFS file, but will have an .fsi extension.Spatial Indexes are needed if the FFS file is later used as the source for spatial queries by the FFS reader.

Reduces the size of the output dataset.A lower compression level will result in faster operation for both reading and writing while a higher compression level will result in smaller file sizes.

Indicates if the resulting file should be optimized for either Little Endian or Big Endian machines.(For example, the architecture of machines running Microsoft Windows is little endian.) Native means the file should be optimized for the type of machine on which it is currently running.

This specification is used to encrypt the output dataset for additional security.This exact passphrase must be used to decrypt this dataset when it is read again.

If this is not used when writing the output dataset, it is not necessary to specify it when reading it in again.
