max_levenshtein_string_size (integer) ​

This configuration parameter affects the behaviour of the LE_DST and DLE_DST functions.

These functions are very compute-intensive. Longer strings require more comparisons, increasing both CPU time and memory usage.

This parameter changes the maximum size (in bytes) of the two input arguments to the function. The default is 255.
