用户可以将 CVM、TencentDB、容器服务等其他云产品的实时日志或业务的存量及增量业务数据，汇聚传输到 ES集群，进行数据的分布式存储、查询分析。
数据采集与同步用户通过 Elasticsearch 中的 Beats 功能，可以把数据传输到 Elasticsearch中进行存储，也可以传输到 Logstash 中进行自定义转换和解析后，再传输到 Elasticsearch 中。
Elasticsearch 提供了易用的 RESTful API，用户可以自行开发客户端，调用数据存储 API，存储数据到Elasticsearch 集群中。
ES 构建在 VPC 内，用户可以非常方便地使用各种数据同步插件，将已有云产品的数据，同步到 ES 集群中。
数据存储腾讯云 ES 提供了多种规格的节点类型和高性能 SSD 磁盘，有效保障数据的读写性能。
支持弹性扩展到上百个节点，能达到 PB 级数据的存储，满足用户不同类型的业务场景。
支持故障节点探测及替换，保障集群高可用性。
具备全文检索功能。
数据查询分析可视化Elasticsearch拥有全文检索、结构化搜索、数据过滤和指标统计等搜索功能，可应用于信息搜索和数据分析等多种场景。
Elasticsearch 提供了简单易用的 RESTful API以及各种语言的客户端，用户可以很方便地构建自己的搜索服务。
使用 Kibana，用户可以方便地在浏览器里对集群的数据进行搜索和统计分析。

Elasticsearch服务的应用开发和运维管理，提供更有力的帮助。腾讯云 ES已提供了包含特性的版本，您可以在创建购买集群时选择，下文介绍各版本详细功能。
购买指引
如上图所示，在腾讯云 ES 创建购买页，有特性版本选项。腾讯云 ES 提供了3种可选的特性版本，版本说明如下：
购买推荐
为了能够使用腾讯云 Elasticsearch更多功能，我们建议您在创建购买集群时，选择白金版，各版本具体功能介绍及区别见下文，产品的定价信息详见 产品定价。
本文对部分常用特性进行了说明，完整的特性及说明，可查看官方说明 Elastic Stack订阅 、API 文档。
注意：
部分功能在不同的特性版本（基础、白金、开源）间有区别。
部分功能在较老的腾讯云 ES 版本不支持，若您遇到此问题可 联系客服咨询。
安全（Security）
支持索引和字段级别读写等细分权限的控制管理，实现数据安全防护、业务访问隔离，向正确的人员授予访问权限，阻止恶意破坏和数据泄露，有效的保障数据安全。
机器学习（Machine Learning）
在自定义数据告警的应用场景中，对于较难设置规则和阈值来定义的变化，可通过结合非监督型机器学习来预测数据的变化趋势和合理的波动范围，在数据偏离正常变化趋势时，发出告警通知。
监控
集群、节点、索引多个维度，全方位监控，实时了解集群运行情况，辅助应用开发及运维。
SQL
提供了通过传统数据库 SQL 工具 ，实现对 Elasticsearch 数据进行全文本检索、数据统计分析功能，支持 CLI、REST等接入方式，白金版还支持 JDBC 连接。可以实现同原有业务系统的无缝对接，降低新技术学习成本。
说明：
SQL 支持方面，开源版集成了其他的 SQL 插件，详细了解和使用可查看 elasticsearch-sql。
本节主要对不同 ES 版本的部分重点功能做对比说明，方便用户了解不同版本功能的区别。因 Elasticsearch正处于快速发展阶段，不同版本对各功能的支持情况也在不断调整，所以我们不保证下述内容能及时跟进社区变化。
