The snippeting feature does not have a performance impact during Data Foundry processing. However, enabling snippeting does affect query runtime performance.
There is no effect on Forge or Dgidx processing time or indexing space requirements on your hard disk.
You can minimize the performance impact on query runtime by limiting the number of words in a property that the MDEX Engine evaluates to identify the snippet. This approach is especially useful in cases where a snippet-enabled property stores large amounts of text.
Provide the
--snip_cutoff <num words>
flag to the dgraph to
restrict the number of words that the MDEX Engine evaluates in a property.
For example, --snip_cutoff 300
evaluates the first 300
words of the property to identify the snippet.
Note
If the
--snip_cutoff
dgraph flag is not specified, or is
specified without a value, the snippeting feature defaults to a cutoff value of
500 words.
