SPLK-1002 Transactions and Event Correlation Practice Question
An analyst is using the transaction command to group events by a field that has high cardinality (millions of unique values). The search is taking too long and consuming too much memory. Which approach should be taken to improve performance?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Reduce the cardinality of the field by using a derived field with fewer values.
High cardinality in the field used by `transaction` causes many open transactions, consuming excessive memory and time. Reducing cardinality (e.g., by using a derived field with fewer unique values) directly addresses this issue. Options B (`maxspan`) and D (`maxevents`) can help limit transactions but do not solve the root cause of high cardinality. Option C (`mvlist`) is not a valid option for the `transaction` command.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Reduce the cardinality of the field by using a derived field with fewer values.
Why this is correct
Correct: Reduces open transactions and improves performance.
- ✗
Use the 'maxspan' option to narrow the time window.
Why it's wrong here
Incorrect: Helps but does not address high cardinality directly.
- ✗
Use the 'mvlist' option to reduce field storage.
Why it's wrong here
Incorrect: Not a valid transaction option.
- ✗
Use the 'maxevents' option to limit number of events per transaction.
Why it's wrong here
Incorrect: Limits events per transaction but does not reduce cardinality.
