Guidelines for adding support for data compression for columns

You can enable data compression for new and existing columns of Standard, Custom, or Hang-off tables. The data compression allows a reduction in size for tables when being implemented.

When adding support for data compression to the columns of standard tables, keep the following considerations in mind:

Data compression logic

The data for compressible columns is compressed using the GZip algorithm. You can override this default data compression logic and provide your custom compression logic by implementing the SCICustomDataCompressor interface.

You must enter the name of the custom class that implements the SCICustomDataCompressor interface in the yfs.db.compression.class=class name property in the customer_overrides.properties file.
