Definition

For technical reasons, DART requires that index records in a data extract have a fix record length. In a non-Unicode system this is always guaranteed automatically.

In a Unicode system, however, index record lengths may vary, even if the number of characters is constant. In this case a fix index record length must be forced externally. You can select here the size of an index record in Bytes.

You have the following choices:

  • Minimum length
    The minimum index record length in a Unicode system is the length assuming that each character is represented by one byte (ca. 50 Bytes).
  • Double length
    This selection sets the index record length in a Unicode system to double the minimum length (ca. 100 Bytes).
  • 55 - 220
    Choose any record length in the range 55 - 220.

What index record length to choose depends on how many "excess" bytes may appear in a segment index key. Such bytes come from Unicode characters that are represented by more than one byte. In UTF-8 encoding a subset of common ASCII characters is encoded by 1 byte.

When writing index records the system checks if the specified record length is sufficient. If the length is too small, the extraction will terminate. In that case a larger index record length must be set.

When reading an extract DART uses the index record length from the time of extraction, even if the extract configuration is currently set up differently.
