Record Size

Fixed-length records have a limit of 64 kilobytes. The record length for a data file is specified with the FairCom DB UCOUNT (unsigned 2-byte integer) datlen parameter.

Variable-length records are limited to 2 GB, with a length represented by the signed 4-byte varlen parameter.

Note: A data record must reside entirely in memory to be added, and must be read into memory as a unit, so memory constraints can also limit record size.
