Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings in conjunction with the embodiments.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

An Elastic Search (ES) system is used in the back-end processing of data. In these applications, the ever-increasing amount of data and the manner in which it is handled, often produces hundreds of millions of records. The massive data can consume a great deal of disk storage space and system resources, seriously reducing cluster performance and even disabling the system. Therefore, ES systems often need to implement management of data storage, periodically deleting old data to ensure performance and stability of the ES system. With the widespread development of big data applications, enterprises are increasingly facing challenges in processing massive amounts of data. The use of multiple Elasticsearch (ES) clusters for index management has become a common solution in the face of massive data. Lifecycle management for ES indexes may use lifecycle management APIs and a currier tool for ES.

The lifecycle management API of the ES allows the user to define indexed lifecycle policies, such as expiration and deletion based on time. By configuring the lifecycle policy, the lifecycle of the index can be automatically managed, thereby reducing the workload of operators. However, current lifecycle management APIs are primarily directed to index management of a single ES cluster, and do not provide a unified management method for spanning multiple ES clusters.

The currator is a popular open source tool for managing and maintaining ES clusters. It provides functions such as index snapshot and clean-up, fragment management, etc. However, the currator is mainly focused on the management of a single ES cluster, and there are some limitations and challenges to the index lifecycle management of multiple ES clusters.

In the related art, there are the following drawbacks in multi-ES cluster index lifecycle management:

1. lack of unified management: the prior art generally fails to provide a unified method to manage index lifecycles across multiple ES clusters. Operators need to manually configure and manage on different clusters, which results in complex operation, error-prone and increased workload.

2. Limited performance: the prior art may face performance bottlenecks in the face of large-scale data sets. The concurrent processing or optimization cannot be performed, so that the processing speed is low, and the real-time service requirement cannot be met.

3. Complex configuration: the configuration process in the prior art is complex, and an operator is required to write complex rules and scripts. This results in an increased risk of configuration errors and also increases the difficulty of system management and maintenance.

4. Lack of intelligence and automation: most of the prior art require an operator to manually perform the index lifecycle management task. The lack of an intelligent decision mechanism does not allow for intelligent automatic execution of indexing operations based on specific conditions or rules.

5. Lack of scalability: the prior art may lack good scalability in processing large-scale data sets. As the amount of data increases, the prior art may not be able to efficiently process and manage a large number of indexes.

In summary, in the related art, there are drawbacks in managing the lifecycle of the multiple ES cluster index, such as lack of unified management, limited performance, complex configuration, lack of intelligence and automation, and poor scalability.

The following embodiments are proposed in view of the above problems existing in the related art.

The method embodiments provided in the embodiments of the present application may be performed in a mobile terminal, a computer terminal or similar computing device. Taking the mobile terminal as an example, fig. 1 is a block diagram of a hardware structure of a mobile terminal of a multi-cluster index management method according to an embodiment of the present invention. As shown in fig. 1, a mobile terminal may include one or more (only one is shown in fig. 1) processors 102 (the processor 102 may include, but is not limited to, a microprocessor MCU or a processing device such as a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 for communication functions and an input-output device 108. It will be appreciated by those skilled in the art that the structure shown in fig. 1 is merely illustrative and not limiting of the structure of the mobile terminal described above. For example, the mobile terminal may also include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1.

The memory 104 may be used to store a computer program, for example, a software program of application software and a module, such as a computer program corresponding to a method for managing multiple cluster indexes in an embodiment of the present invention, and the processor 102 executes the computer program stored in the memory 104 to perform various functional applications and data processing, that is, implement the above-mentioned method. Memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory remotely located relative to the processor 102, which may be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The transmission means 106 is arranged to receive or transmit data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, simply referred to as NIC) that can connect to other network devices through a base station to communicate with the internet. In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used to communicate with the internet wirelessly.

In this embodiment, a method for managing multiple cluster indexes is provided, and fig. 2 is a flowchart of a method for managing multiple cluster indexes according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:

It is widely used for real-time data indexing, searching and analysis, and is suitable for processing large and varied data.

That is, the index management unit supports a cluster administrator to realize daily management work of one-stop multi-ES cluster indexes through a multi-cluster index management system, including index creation, index template definition, index reservation period definition, index modification, index deletion and cross-cluster replication of the indexes.

For a plurality of ES clusters distributed in different region data centers, the management system with multi-cluster index can conveniently manage the ES clusters, and meanwhile, the management system with multi-cluster index can also support the elastic search clusters with different versions, so that the manager is shielded from the differences among the different versions, and the management is simpler and more convenient. That is, versions of clusters included in the plurality of clusters may be the same or different.

The scheduler unit is used for connecting to the ES cluster and acquiring ES indexes and document data through a network protocol. And acquiring a cluster index list and a reserved period of indexes from a database, periodically polling the indexes meeting the cleaning conditions through a timing task set by a scheduler, and cleaning the indexes meeting the conditions.

In the replication process, the pressure of the detection cluster is also supported, and the replication rate is dynamically adjusted according to the pressure of the cluster, so that the stability of other services is ensured.

The database is used for storing metadata, operation data and some configuration data generated in the index lifecycle management process, including configuration data such as a data center, an ES cluster, an index and the like, and metadata such as a scheduling job history record, an administrator login and operation record, an Es cluster version difference and the like.
