+# SpaceTL Delete
+
+## 1. Overview
+
+IoTDB supports configuring the SpaceTL deletion policy through parameters: when the storage space of the last-level storage tier (object storage space is considered unlimited) is insufficient, users can choose whether to trigger the SpaceTL deletion mechanism to free up space.
+
+Note: This mechanism only deletes files in the last storage tier.
+
+## 2. Parameter Introduction
+
+| Parameter Name            | Description                                                                                                                                                                    | Default Value | Effective Mode |
+| --------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------- | ---------------- |
+| `dn_tier_full_policy` | Behavior policy when the storage space of the last-level storage tier is insufficient. Configurable options:1. NULL: Take no action.2. DELETE: Enable SpaceTL data deletion. | NULL          | Hot Reload     |
+
+Parameter Explanation:
+
+* If the last-level storage tier includes object storage, SpaceTL will not be triggered.
+* This parameter works in conjunction with the `dn_default_space_usage_thresholds`parameter. SpaceTL is triggered when the available space of the last-level storage tier falls below the `space_usage_thresholds`. By default, deletion begins when disk space usage reaches 85% and continues until usage drops below 85%.
+
+## 3. Usage Example
+
+In a three-tier storage setup, when the storage space of the last tier reaches 85%, the SpaceTL deletion mechanism is triggered to start deleting files.
+
+```Properties
+# data dirs
+# If this property is unset, system will save the data in the default relative path directory under the IoTDB folder(i.e., %IOTDB_HOME%/data/datanode/data).
+# If it is absolute, system will save the data in exact location it points to.
+# If it is relative, system will save the data in the relative path directory it indicates under the IoTDB folder.
+# If there are more than one directory, please separate them by commas ",".
+# If tiered storage is enabled, please separate directories of different tiers by semicolons ";".
+# Use keyword OBJECT_STORAGE to denote object storage media, object storage can only exist on the last tier and must have local dirs in the front tiers.
+# Note: If data_dirs is assigned an empty string(i.e.,zero-size), it will be handled as a relative path.
+# effectiveMode: hot_reload
+# For windows platform
+# If its prefix is a drive specifier followed by "\\", or if its prefix is "\\\\", then the path is absolute. Otherwise, it is relative.
+# dn_data_dirs=data\\datanode\\data
+# For Linux platform
+# If its prefix is "/", then the path is absolute. Otherwise, it is relative.
+dn_data_dirs=/data1/data;/data2/data,/data3/data;/data4/data
+
+# Default tier TTL. When the survival time of the data exceeds the threshold, it will be migrated to the next tier.
+# Negative value means the tier TTL is unlimited.
+# effectiveMode: restart
+# Datatype: long
+# Unit: ms
+tier_ttl_in_ms=86400000;864000000;-1
+
+# Disk usage threshold, data will be moved to the next tier when the usage of the tier is higher than this threshold.
+# If tiered storage is enabled, please separate thresholds of different tiers by semicolons ";".
+# effectiveMode: hot_reload
+# Datatype: double(percentage)
+dn_default_space_usage_thresholds=0.75;0.8;0.85
+
+# How to deal with the last tier?s data when its used space has been higher than its dn_default_space_usage_thresholds.
+# The info of the two policies are as follows:
+# effectiveMode: hot_reload
+# 1. NULL: do nothing.
+# 2. DELETE: delete the oldest data.
+dn_tier_full_policy=DELETE
+```
+
+In this example, three tiers of storage are configured as follows:
+
+| Tier Level | Storage Directories           | Data Retention Time                                 | Disk Storage Space Threshold                                                            |
+| ------------ | ------------------------------- | ----------------------------------------------------- | ----------------------------------------------------------------------------------------- |
+| Tier 1     | `/data1/data`             | Retained for 1 day; exceeded data moves to Tier 2   | Data moves to Tier 2 when disk usage reaches 75%                                        |
+| Tier 2     | `/data2/data,/data3/data` | Retained for 10 days; exceeded data moves to Tier 3 | Data moves to Tier 3 when disk usage reaches 80%                                        |
+| Tier 3     | `/data4/data`             | No expiration time; data is stored indefinitely     | Deletes some files when disk usage reaches 85% (due to`dn_tier_full_policy=DELETE`) |

+
+In a three-tier storage setup, when the storage space of the last tier reaches 85%, the SpaceTL deletion mechanism is triggered to start deleting files.

+
+## 1. Overview
+
+IoTDB(V1.3.2+) supports configuring the SpaceTL deletion policy through parameters: when the storage space of the last-level storage tier (object storage space is considered unlimited) is insufficient, users can choose whether to trigger the SpaceTL deletion mechanism to free up space.
+
+Note: This mechanism only deletes files in the last storage tier.
+

+# SpaceTL 删除
+
+## 1. 概述
+
+IoTDB 支持通过参数配置 SpaceTL 删除策略：即当最后一级存储层（对象存储空间被视为无限）的存储空间不足时，可选择是否触发 SpaceTL 删除机制以释放空间。
+
+注意：该机制仅会删除最后一个存储层中的文件。
+
+## 2. 参数介绍
+
+| 参数名                 | 描述                                                                                                    | 默认值 | 生效方式 |
+| ------------------------ | --------------------------------------------------------------------------------------------------------- | -------- | ---------- |
+| dn\_tier\_full\_policy | 最后一级存储层存储空间不足时的行为策略。可配置：1. NULL：不做任何处理1. DELETE：开启 SpaceTL 删除数据。 | NULL   | 热加载   |
+
+参数说明：
+
+* 若最后一级存储层包含**对象存储**则不触发 SpaceTL
+* 该参数和 dn\_default\_space\_usage\_thresholds 参数联动，当最后一级存储层的可用空间低于 space\_usage\_thresholds 时触发 SpaceTL；默认当磁盘空间占用到达 85% 的时候开始删除直至空间占用降到 85% 以下才会停止
+
+## 3. 使用示例
+
+以三级存储为例，当最后一级存储空间到达85%时，触发 SpaceTL 删除机制开始删除文件。
+
+```Properties

+# SpaceTL 删除
+
+## 1. 概述
+
+IoTDB 支持通过参数配置 SpaceTL 删除策略：即当最后一级存储层（对象存储空间被视为无限）的存储空间不足时，可选择是否触发 SpaceTL 删除机制以释放空间。
+
+注意：该机制仅会删除最后一个存储层中的文件。

+# SpaceTL 删除
+
+## 1. 概述
+
+IoTDB 支持通过参数配置 SpaceTL 删除策略：即当最后一级存储层（对象存储空间被视为无限）的存储空间不足时，可选择是否触发 SpaceTL 删除机制以释放空间。
+
+注意：该机制仅会删除最后一个存储层中的文件。
+
+## 2. 参数介绍
+
+| 参数名                 | 描述                                                                                                    | 默认值 | 生效方式 |
+| ------------------------ | --------------------------------------------------------------------------------------------------------- | -------- | ---------- |
+| dn\_tier\_full\_policy | 最后一级存储层存储空间不足时的行为策略。可配置：1. NULL：不做任何处理1. DELETE：开启 SpaceTL 删除数据。 | NULL   | 热加载   |
+
+参数说明：
+
+* 若最后一级存储层包含**对象存储**则不触发 SpaceTL
+* 该参数和 dn\_default\_space\_usage\_thresholds 参数联动，当最后一级存储层的可用空间低于 space\_usage\_thresholds 时触发 SpaceTL；默认当磁盘空间占用到达 85% 的时候开始删除直至空间占用降到 85% 以下才会停止
+
+## 3. 使用示例
+
+以三级存储为例，当最后一级存储空间到达85%时，触发 SpaceTL 删除机制开始删除文件。
+
+```Properties
+# data dirs
+# If this property is unset, system will save the data in the default relative path directory under the IoTDB folder(i.e., %IOTDB_HOME%/data/datanode/data).
+# If it is absolute, system will save the data in exact location it points to.
+# If it is relative, system will save the data in the relative path directory it indicates under the IoTDB folder.
+# If there are more than one directory, please separate them by commas ",".
+# If tiered storage is enabled, please separate directories of different tiers by semicolons ";".
+# Use keyword OBJECT_STORAGE to denote object storage media, object storage can only exist on the last tier and must have local dirs in the front tiers.
+# Note: If data_dirs is assigned an empty string(i.e.,zero-size), it will be handled as a relative path.
+# effectiveMode: hot_reload
+# For windows platform
+# If its prefix is a drive specifier followed by "\\", or if its prefix is "\\\\", then the path is absolute. Otherwise, it is relative.
+# dn_data_dirs=data\\datanode\\data
+# For Linux platform
+# If its prefix is "/", then the path is absolute. Otherwise, it is relative.
+dn_data_dirs=/data1/data;/data2/data,/data3/data;/data4/data
+
+# Default tier TTL. When the survival time of the data exceeds the threshold, it will be migrated to the next tier.
+# Negative value means the tier TTL is unlimited.
+# effectiveMode: restart
+# Datatype: long
+# Unit: ms
+tier_ttl_in_ms=86400000;864000000;-1
+
+# Disk usage threshold, data will be moved to the next tier when the usage of the tier is higher than this threshold.
+# If tiered storage is enabled, please separate thresholds of different tiers by semicolons ";".
+# effectiveMode: hot_reload
+# Datatype: double(percentage)
+dn_default_space_usage_thresholds=0.75;0.8;0.85
+
+# How to deal with the last tier?s data when its used space has been higher than its dn_default_space_usage_thresholds.
+# The info of the two policies are as follows:
+# effectiveMode: hot_reload
+# 1. NULL: do nothing.
+# 2. DELETE: delete the oldest data.
+dn_tier_full_policy=DELETE
+```
