Summary by CodeRabbit

• Chores
  • Added configurable prewarm task count settings, allowing operators to tune data prewarming performance on a per-shard basis. The new option defaults to 3 tasks per shard and can be configured through command-line parameters or configuration files for optimal performance across various deployment scenarios.

Walkthrough

A new configuration flag eloq_store_prewarm_task_count is introduced to EloqStore with a default value of 3, representing the prewarm task count per shard. The flag is wired into the EloqStoreConfig constructor using the existing priority pattern: command-line flag preference over INI configuration.

Changes

Cohort / File(s)	Summary
Configuration flag addition store_handler/eloq_data_store_service/eloq_store_config.cpp	Introduced new global flag DEFINE_uint32(eloq_store_prewarm_task_count, 3, ...) and added initialization logic in EloqStoreConfig constructor to populate eloqstore_configs_.prewarm_task_count from either the command-line flag or INI config, following the established pattern used for similar options.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• The change adds a new configuration option in a single file using a well-established and consistently-applied pattern
• Verify that the default value (3) and parameter name are appropriate for the per-shard prewarm task context
• Confirm that the priority logic (command-line flag → INI config → default) is correctly implemented and consistent with other similar flags

Poem

🐰 A little flag hops into place,
Prewarm tasks dance with graceful grace,
Per shard, the count now stands at three,
Config patterns thrive in harmony! ✨

Title check	❓ Inconclusive	The title 'adapt parameter' is vague and generic, lacking specificity about which parameter or what adaptation is being made.	Provide a more descriptive title that clearly identifies the parameter being adapted (e.g., 'Add eloq_store_prewarm_task_count configuration flag').

97-99: LGTM! Consider adding bounds validation.

The flag definition is correct and follows the established pattern. The default value of 3 tasks per shard is reasonable.

Consider adding runtime validation (similar to num_threads at line 235) to ensure the value is at least 1 and optionally capped at a reasonable maximum to prevent resource exhaustion from misconfiguration. However, this is optional since most other config values in the file don't have validation.

Example validation that could be added after line 434:

eloqstore_configs_.prewarm_task_count =
    std::max(eloqstore_configs_.prewarm_task_count, uint32_t(1));

429-434: LGTM! Configuration loading is correctly implemented.

The implementation follows the established pattern consistently:

• Command-line flag precedence over INI config
• Correct use of GetInteger for the uint32 type
• Proper fallback to the flag default value
• Logical placement adjacent to the related prewarm_cloud_cache configuration
