Types of Splunk SPL Commands 💡

1️⃣ Streaming Commands

Streaming commands process events as they flow through the search pipeline, working on one event at a time.

Types of Streaming Commands:

1.Distributable Streaming:

• Run on indexers for better performance.
• Examples: eval, fields, where, regex.
• Key Use: Parallel processing of events without worrying about order.

2.Centralized Streaming:

• Run on the search head because event order matters.
• Examples:head, streamstats, dedup (specific modes).
• Key Use: When the sequence of events impacts the result.

2️⃣ Non-Streaming Commands

Non-streaming commands don’t process events one by one; they often require all events or influence how the search runs.

Categories of Non-Streaming Commands:

1.Transforming Commands:

• Turn raw data into tables and statistics for reports and visualizations.
• Examples: stats, chart, timechart.
• Key Use: Creating summary reports, trends, and charts.

2.Generating Commands:

• Start a search or create data without prior input.
• Examples: makeresults, inputlookup, datamodel.
• Key Use: Generate initial data or enrich searches with additional information.

3.Orchestrating Commands:

• Control how a search is executed rather than the results.
• Examples: redistribute, noop, localop.
• Key Use: Optimize performance or manage search behavior.

4.Dataset Processing Commands:

• Work on the entire dataset, requiring full data visibility.
• Examples: sort, eventstats, fillnull.
• Key Use: Process or manipulate data globally for accuracy.
