Features

• Bulk Data Operations - Provides high-throughput data ingestion using bulk index and update requests.
• Elasticsearch Connectors - Provides a specialized Go driver for establishing secure connections and integrating with Elasticsearch clusters.
• Cluster Connectivity - Establishes programmatic links to a distributed search cluster using specific URLs and configuration parameters.
• Configuration Settings - Provides custom network settings to manage communication behavior between the Go client and the server.
• Backup and Recovery - Implements full lifecycle data protection through snapshot creation and restoration.
• Backup Repositories - Configures local and remote storage repositories used for storing cluster snapshots.

• Full Text Search - Implements full-text search capabilities using complex queries, filters, and sorting.
• Search Index Management - Offers comprehensive tools for configuring, querying, and maintaining search indices.
• JSON Indexing - Adds data to search indices by providing content as JSON objects or raw strings.
• Indexed Data Aggregations - Produces summarized analytical reports by computing metrics and buckets over indexed document sets.
• Index Lifecycle Management - Automates index creation, deletion, and configuration using templates and REST APIs.

• API Wrappers - Provides a structured Go programmatic interface to the Elasticsearch REST API.
• Elasticsearch Health Monitors - Implements specialized interfaces for tracking the operational health and availability of Elasticsearch clusters.
• Statistical Distribution Analysis - Calculates metrics and summaries using aggregations and facets to identify statistical distributions and percentiles.
• Bulk Request Buffering - Optimizes data flow by collecting multiple requests and flushing them based on specific intervals or item counts.
• Shard Allocation Monitoring - Monitors data distribution across nodes by retrieving shard allocation data from the cluster.
• Automated Rollup Engines - Summarizes historical data into compact forms by creating and controlling rollup jobs.
• Snapshot Metadata Retrievers - Provides capabilities to query and filter metadata for existing cluster snapshots within a repository.
• Bulk Data Operations - Removes multiple documents efficiently in a single request using identifiers and routing keys.
• Document Source Filtering - Controls which fields return in a document hit by including or excluding specific paths.
• Bulk Data Ingestion - Optimizes write performance through buffered bulk operations for high-throughput data ingestion.
• Percolator Querying - Determines which stored queries are satisfied by matching them against a new document.
• Cursor-Based Iteration - Retrieves large volumes of documents by scrolling through the data in manageable batches.
• Result Streaming - Iterates through large datasets by managing scroll identifiers to retrieve documents in memory-efficient batches.
• Search Engine Scripting - Supports the execution of custom computations and scoring via scripts stored within Elasticsearch.
• Search and Analytics Engines - Generates statistical summaries and trend analysis using aggregations and facets.
• Search Result Sorting - Orders documents based on relevance, specific fields, distance, or custom scripts.
• Search Suggestions - Provides spell-checking and search-as-you-type suggestions based on rewritten query logic.
• Shard Distribution Inspection - Retrieves snapshots of shard distribution and disk space usage across data nodes.
• Shard Allocation Rerouting - Moves or cancels shard allocations across nodes using commands with timeout and dry run options.
• Request Cancellations - Controls request lifecycles via Go contexts to enable automatic cancellation and timeout management.
• Circuit Breakers - Monitors node health and prevents cascading failures by marking connections as dead based on request success.
