How do you embed a RegEx in Oracle PL/SQL to extract a target string (ex: DELINQUENT), assess its performance impact in critical transactions, and is this approach recommended?
hey, i think using oracle’s built in regex functions works, but make sure to run heavy load tests. have u noticed lag in critical transactions? curious if anyone tried other tweaks to boost perf. what are your experiences with this?
Experience has shown that using Oracle’s built-in regex functions, such as REGEXP_SUBSTR, can indeed simplify the process of extracting specific patterns from data. However, there is a performance cost when these functions are applied to large datasets or critical transaction workloads. My approach involves isolating the regex operations to smaller data subsets and using comprehensive performance tests prior to deployment. This helps maintain optimal query performance. In cases where heavy transactions are expected, consider a more pre-processed or indexed solution to mitigate potential slowdowns.
