Review auto-configuration logic for RocksDB background jobs.
The auto-configuration logic described from lines 361 to 382 is complex and could benefit from additional examples or a more detailed explanation. Ensuring that users fully understand how these settings interact could prevent misconfigurations that might lead to performance degradation.

Clarify dynamic configuration capabilities for replication settings.
The settings for throttle-bytes-per-second and rsync-timeout-ms include support for dynamic changes, which is a powerful feature. It might be helpful to provide examples of how to use these dynamic settings effectively, especially in scenarios involving large data transfers or high network latency.

13-13: Header inclusion approved.The inclusion of
"rocksdb/status.h"is appropriate as it is used throughout the file for handling status checks from RocksDB operations.
63-63: Updated error handling logic inGeoAddCmd::Do().The handling of
rocksdb::Statusis now more granular, which improves error specificity and debugging capabilities.
107-107: Enhanced error handling inGeoPosCmd::Do().The addition of handling for
IsInvalidArgumentincreases robustness and aligns with other similar functions.
167-174: Refined error handling inGeoDistCmd::Do().The addition of specific checks for
IsInvalidArgumentand other status-related errors enhances the function's ability to handle edge cases effectively.Also applies to: 174-174
246-246: Improved error handling inGeoHashCmd::Do().The handling of
IsInvalidArgumenterrors is a good addition, ensuring that the function can gracefully handle more error scenarios.
318-324: Comprehensive updates inGetAllNeighbors.The changes in error handling, sorting logic, and the handling of
storeandstoredistoptions enhance the function's flexibility and correctness. The error handling is now more robust, and the sorting logic is clearer and more configurable.Also applies to: 350-355, 367-378
* modify geo.tcl ci * modify go_test * modify default.conf * modify code based on review
Fixed several geo bugs:
Modified error messages to be consistent with Redis. For example, for the same error, Pika returns ERR Invalid argument, while Redis returns WRONGTYPE Operation against a key holding the wrong kind of value.
When using the GEORADIUS command, Pika's default sort value is Unsort, whereas Redis's default sort value is Asc.
When the store and storedist options are enabled in the GEO command, Pika does not ensure data consistency between the storage layer and the cache layer.
When the store and storedist options are enabled in the GEO command, Pika appends the new results to the target key, while Redis replaces the existing data in the target key with the new data.
There is a logical error in Pika when finding the search boundaries (using geohashBoundingBox).
There is a logical error in Pika when calculating the distance between two points (using geohashGetDistance).
There is a logical error in Pika when validating the step's validity.
Result display:
Pika can pass all geo TCL test cases except for the unsupported geo commands.
修改了若干关于geo的bug
修改了与 Redis 不一致的报错内容。例如，对于相同的错误，Pika 报错为 ERR Invalid argument，而 Redis 报错为 WRONGTYPE Operation against a key holding the wrong kind of value。
使用 GEORADIUS 命令时，Pika 的默认排序值为 Unsort，而 Redis 的默认排序值为 Asc。
在 GEO 命令的 store 和 storedist 选项启动时，Pika 没有保证存储层和缓存层的数据一致性。
在 GEO 命令的 store 和 storedist 选项启动时，Pika 将新的结果追加到目标键中，而 Redis 则是用新数据替换目标键中的现有数据。
在查找搜索边界时（geohashBoundingBox），Pika 的逻辑有误。
在判断两点距离时（geohashGetDistance)，Pika 的逻辑有误。
在检验 step 的有效性时，Pika 的逻辑有误。
