Line range hint
139-191: Query logic is large for inlining
query_offsetis a lengthy method to retrieve offsets based on time bounds and keys.
- Inlining a large function can increase compile times and possibly reduce clarity, though it may reduce call overhead in tight loops.
- No functional issues spotted.
Line range hint
378-385: Use of#[inline]on a helper
build_keyis a straightforward helper function to concatenate strings.
- Consider using
format!("{}#{}", topic, key)for even clearer code.- No functional concerns.
-fn build_key(topic: &str, key: &str) -> String { - let mut keys = String::new(); - keys.push_str(topic); - keys.push('#'); - keys.push_str(key); - keys +fn build_key(topic: &str, key: &str) -> String { + format!("{}#{}", topic, key) }

Line range hint 53-60: Adding #[inline] to constructor method
This method initializes several fields and sets up the IndexService.
- The addition of
#[inline]is a valid optimization hint for performance-sensitive contexts. - Ensure that calling this constructor is frequent enough to justify inlining overhead.
Line range hint 68-99: Consider the cost-benefit of inlining I/O-bound logic
The load method performs file system operations and populates the in-memory index list. Inlining large or I/O-heavy functions might not yield significant speed benefits. Nonetheless, there is no functional risk in using #[inline].
Line range hint 101-109: Small accessor function inline
get_total_size is a small accessor-like function, so using #[inline] is consistent with Rust best practices for trivial getters.
Line range hint 111-128: Check for edge cases in expiration logic
delete_expired_file walks the index list for files with end_phy_offset < offset. The logic appears sound, and applying #[inline] is acceptable.
- Ensure that the list ordering is always guaranteed such that earlier files come first.
Line range hint 130-137: Destroy method inlined
destroy clears and destroys index files.
- Infrequent usage of this method is typical (e.g., shutdown scenario). Inlining might not offer much benefit.
- Functionality appears correct.
Line range hint 193-256: Index-building logic
build_index is critical for updating index files.
- Make sure the concurrency around
index_filereferences and default creation is safe. - Inlining a large function is a trade-off between performance and code size.
Line range hint 257-283: Consider naming consistency
put_key aligns with the way other internal methods are named. No issues with adding #[inline].
- Optionally, rename
msgtodispatch_requestfor clarity.
Line range hint 284-304: Retries inlined
retry_get_and_create_index_file attempts up to MAX_TRY_IDX_CREATE times to create an index file.
- Code logic seems robust.
- No potential infinite loops since
MAX_TRY_IDX_CREATEis finite.
Line range hint 305-357: Background flush inlined
get_and_create_last_index_file can spawn an async flush via tokio::spawn.
- Inlining makes sense if this is a frequent path.
- Ensure a Tokio runtime is properly available.
Line range hint 358-377: Flush method
flush potentially updates the store checkpoint if the index file is fully written.
- Good use of inlining if flush is called in performance-sensitive loops.
- Functional correctness looks fine.
