The compilation explains multiple parameters values ‌based on which you can select the chunk size. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-comms_media_energy_managed-264-0-0-production-enus/ff4079f6-a384-475c-b863-578bbbb0ef9b/images/icon_note.png) Note The chunk size values are approximate estimations, as the actual value can vary depending on the customer's dataset. ## Compile PCP Parameter This table defines the variable chunking logic for multiple values of PCP.

PCP Count	Description	Chunk Size
Less than or equals 5000	Low memory footprint, maximize throughput	2000
5000–10000	Moderate memory, balanced jobs	1000
Greater than 10000	High volumes require smaller chunks to avoid heap pressure	500

## Compile Product Hierarchy Parameter This table defines the variable chunking logic for multiple combinations of Products, and Hierarchy Complexity. In addition to the previous configurations, the additional factor that contributes to chunk size is the attribute coverage. In general, these numbers are considering each product bundle has half of the PCIs assigned with the attributes, a mix of normal and picklist attributes. For example, each product carries 10 attributes: five standard (normal) attributes and five picklist-type attributes.

Product	Hierarchy Complexity	Chunk Size
Less than 5000	Simple (10 PCIs per Bundle)	100
Less than 5000	Moderate (20 PCIs per Bundle)	75
5000–10000	Simple (10 PCIs per Bundle)	75
5000–10000	Moderate (20 PCIs per Bundle)	50
Greater than 10000	Moderate+ (30+ PCIs per Bundle)	30–50

## Compile Context Rules Parameter This table defines the variable chunking logic for different values and descriptions for Context Rules.

Rules Count	Description	Chunk Size
Less than or equals 5000	Simple rule evaluation, low memory	2000
5000–10000	Moderate rule set, balanced processing	1000
Greater than 10000	Large rule sets need smaller chunks	500

## Compile Price List To PBE Ranges This table defines the variable chunking logic for multiple combinations of Products and PLEs.

Products	PLEs	Chunk Size
Less than 5000	Less than 20000	50
5000–10000	Less than 30000	40
10000–25000	Less than 50000	30
25000–50000	Less than 100000	20

## Compile Pricing This table defines the variable chunking logic for different set of PLEs.

PLEs	Chunk Size
Less than 20000	50
20000–50000	40
50000–100000	30
Greater than 100000	20

## Compile Promo Items This table defines a variable chunking logic for processing promotion items.

Promotion Items	Chunk Size
Less than 10000	100
10000–50000	70
50000–100000	50
Greater than 100000	30

Here’s the representation of a configuration script: ![Chunking Script](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ind-comms_media_energy_managed-264-0-0-production-enus/ff4079f6-a384-475c-b863-578bbbb0ef9b/comms_media_energy_managed/images/chunkingscript.png) Also, with an invalid JSON script, the system throws an error but still gives output based on the default values for the configuration parameters.
