面向全文检索的分级存储方法及装置
摘要：
本发明公开了一种面向全文检索的分级存储方法及装置，所述方法包括：获取SQL语句，创建全文检索表，并将所述全文检索表持久化到Zookeeper中；配置ElasticSearch集群中一部分节点使用SSD盘，另一部分节点使用SATA盘，并在每个节点上安装自定义的ElasticSearch插件；数据加载工具通过ElasticSearch集群的调用接口API将文档数据加载到ElasticSearch集群中，通过所述ElasticSearch插件对请求进行过滤，并使用预先存储的全文检索表中的元数据进行索引创建；通过所述ElasticSearch插件运行监听策略，监听Zookeeper中表的元数据信息的变化，并应用分级存储策略，执行定时回滚策略，将回滚任务下发给ElasticSearch集群。
摘要（英）：

The invention discloses a hierarchical storage method and device for full-text retrieval, and the method comprises the steps of obtaining an SQL statement, creating a full-text retrieval table, and enabling the full-text retrieval table to be persistent in a Zookeeper; configuring one part of nodes in the ElasticSearch cluster to use an SSD disk, configuring the other part of nodes in the ElasticSearch cluster to use an SATA disk, and installing a user-defined ElasticSearch plug-in on each node; using the data loading tool to load the document data into the ElasticSearch cluster through a calling interface API of the ElasticSearch cluster; filtering the request through the ElasticSearch plug-in, and carrying out index creation by using metadata in a pre-stored full-text retrieval table; and running a monitoring strategy through the ElasticSearch plug-in, monitoring the change of metadata information of a table in the Zookeeper, executing a timing rollback strategy by applying a hierarchical storage strategy, and issuing a rollback task to an ElasticSearch cluster.
