对象存储

Datalayers 采用云原生存算分离架构，将计算层和存储层解耦，使您能够根据业务需求独立扩展计算和存储资源。这种架构避免了资源浪费，优化了成本效益，同时提升了系统的整体性能、安全性和可维护性。因此，在具备对象存储服务的情况下，我们推荐用户优先选择存算分离的部署方案。

目前，Datalayers 已支持主流公有云的对象存储服务，包括 AWS、GCP、Azure、阿里云、腾讯云、华为云等。同时，对于兼容 S3 协议的对象存储服务（如 MinIO）也可直接接入。

优点

​​弹性扩展​​：计算与存储解耦，支持独立按需扩展
​​运维简单​​：使用公有云对象存储时，存储运维由云服务商保障，极大降低运维成本
​​快速扩容​​：在公有云环境中可通过简单操作实现存储容量的快速扩展
​​高可用性​​：公有云对象存储通常提供高达 99.999999999%（11个9）的数据持久性，并支持跨区域容灾

启动对象存储服务

配置对象存储服务

如需使用对象存储服务，我们需修改配置文件，配置相应的服务地址，如下（以 S3 为例）：

# The configurations of the S3 object store.
# We support both virtual-hosted–style and path-style URL access in S3 service.
# Set To true to enable virtual-hosted–style request.
# In a virtual-hosted–style URI, the bucket name is part of the domain name in the URL,
# the endpoint use the following format: https://bucket-name.s3.region-code.amazonaws.com.
# In a path-style URI, the bucket is the first slash-delimited component of the Request-URI,
# the endpoint use the following format: https://s3.region-code.amazonaws.com/bucket-name.
# We support path-style URL access in minio even though your minio service does not enable this feature,
# and you are also allowed accessing with path-style like http://<ip>:<port> or http://minio.example.net
# if you set `virtual_hosted_style` to false
[storage.object_store.s3]
bucket = "datalayers"
access_key = "CPjH8R6WYrb9KB6riEZo"
secret_key = "TsTal5DGJXNoebYevijfEP2DkgWs96IKVm0uores"
endpoint = "https://bucket-name.s3.region-code.amazonaws.com"
# region = "region-code"
# write_rate_limit = "0MB"
virtual_hosted_style = true

# [storage.object_store.azure]
# container = "datalayers" # your can change it as you want
# account_name = "PLEASE CHANGE ME"
# account_key = "PLEASE CHANGE ME"
# endpoint = "PLEASE CHANGE ME"
# write_rate_limit = "0MB"

# [storage.object_store.gcs]
# bucket = "datalayers" # your can change it as you want
# scope = "PLEASE CHANGE ME"
# credential_path = "PLEASE CHANGE ME"
# endpoint = "PLEASE CHANGE ME"
# write_rate_limit = "0MB"

指定使用对象存储服务

启动对象存储服务后，通过修改以下配置，即可让新创建的表默认使用该对象存储服务，本配置以 s3 为例，配置文件如下：

[storage.object_store]
# Supported (the case is not sensitive):
# - s3.
# - azure.
# - gcs.
# - local (only working in standalone mode)
# Default: local|fdb
default_storage_type = "s3"
