What is Elasticsearch?
Elasticsearch is a distributed, scalable, and real-time search and data analysis engine built on top of the full-text search library Apache Lucene?. It supports seamless expansion from a single node to hundreds of nodes and enables storage and query of structured or unstructured data amounts up to petabytes.
What Business Scenarios is ES Suitable for?
ES fully retains the features of Elasticsearch in terms of massive data search such as full-text search, quasi-real-time search, and structured search. It is widely used in business scenarios like log analysis and in-site search. It enables you to build log service systems for other Tencent Cloud services in use such as CVM and TKE and can also integrate search services into your existing business service frameworks.
What is Elasticsearch Service (ES)?
Tencent Cloud ES is a cloud-based cluster service built on the open-source search engine Elasticsearch. It inherits the openness, compatibility, and usability of Elasticsearch and provides a sufficiency of hardware resources, user-friendly graphical creation and management tools, and comprehensive technical and OPS support.
How long after converting from pay-as-you-go to monthly/annual subscription will the billing be based on the subscription?
It takes effect immediately after successful payment.
I have an unpaid switch order. Will the order still be valid if I upgrade the cluster configuration?
No. A new purchase order will be generated when the billing mode is switched from pay-as-you-go to monthly subscription, but if you change the configuration of the cluster before paying the order, the amount of the new purchase order will not match the cluster, and the unpaid order cannot be paid.
If you still need to change the payment method of the cluster, you need to cancel the current unpaid order in Order Center first, then carry out the new conversion operation.
Does Replacing the Type of Cloud Disk Supported After Successful Purchase?
Currently, switching types of cloud disks is not supported. You can create a snapshot for backup and then use the snapshot to create a cloud disk of your desired type.
How is the ES Annual and Monthly Subscription refund amount calculated?
Refund amount = current effective order amount + unstarted order amount - used resource value
The value of resources used is calculated based on the following strategy:
For used cluster costs, if the day of initiating a refund completes a whole month, it will be deducted by the whole month. If it does not complete a whole month, it will be deducted based on usage. For specific refund rules, please refer to Annual and Monthly Refund.
How do I choose the appropriate node and disk when creating a cluster?
For calculations regarding the node specifications of ES service, you can refer to the Evaluation of Cluster Specification and Capacity Configuration.
Does ES have a trial or beta version?
ES offers a 30-day Free Trial Version. You can claim the trial. If you have already claimed it, you can opt to purchase the pay-as-you-go version first. The pay-as-you-go version charges based on usage, making it convenient for trial or testing purposes.
Does the ES cluster support exporting cluster certificates?
For clusters with HTTPS transfer protocol enabled, ES allows certificate export operations in the console under Access Control > Cluster Access Control module. You can export both server-side and client-side certificates.
