Is it true that a heavy forwarder is used for sending event-based data to indexers?

A heavy forwarder is indeed used to send event-based data to indexers, and this statement is true. Heavy forwarders are advanced components in Splunk's data pipeline, designed to process and forward data from various data sources to indexers for storage and analysis.

What distinguishes a heavy forwarder is its ability to perform parsing and indexing on the data it processes. This capability allows it to apply filters, remove unnecessary data, and even perform transformations before sending the data to the indexers. By doing so, heavy forwarders help optimize the data that reaches the indexers, ensuring that only relevant and necessary information is collected and processed, which can improve overall system efficiency and reduce storage costs.

In scenarios where large volumes of data are generated at the source, heavy forwarders play a crucial role. They can alleviate the burden on indexers by doing some pre-processing work, thereby facilitating a more streamlined and efficient data indexing process on the receiving end.

The other options suggest the statement is false, which does not align with the functional capabilities of heavy forwarders in the Splunk ecosystem.
