v0.4.0 Release

This release adds some features around managing indices.

Breaking Changes

• Renamed ClusterSettings struct to Settings - This struct is now used when listing Cluster or Index settings.
• Renamed func (c *Client) GetSettings() method to func (c *Client) GetClusterSettings() to differentiate between Cluster or Index settings.
• Renamed func (c *Client) SetSetting method to func (c *Client) SetClusterSetting to differentitate between Cluster or Index settings.
• Added indexSettings map[string]interface{} to the arguments of func (c *Client) RestoreSnapshotIndices to allow setting specific index settings when restoring an index.

New APIs

• func (c *Client) DeleteIndex(indexName string) error - Deleting an index
• func (c *Client) GetPrettyIndexSettings(index string) (string, error) - Get a human readable JSON of the settings of an index
• func (c *Client) GetIndexSettings(index string) ([]Setting, error) - Get the settings of an index
• func (c *Client) SetIndexSetting(index, setting, value string) (string, string, error) - Set the settings of an index
• func (c *Client) GetPrettyIndexMappings(index string) - Get a human readable JSON of the mappings of an index
• func (c *Client) AnalyzeText(analyzer, text string) ([]Token, error) - Call the Elasticsearch analyze API to preview how given text will be broken down into tokens.
• func (c *Client) AnalyzeTextWithField(index, field, text string) ([]Token, error) - Call the Elasticsearch analyze API with a specific field to preview how the text will be broken down into tokens for that field.

Changes

• Added additional fields to the Client struct to support more connection properties
  • Secure - boolean whether to connect using HTTPS or not
  • Auth - struct containing username and password for HTTP basic auth
  • Timeout - set a time.Duration for the API calls to Elasticsearch
  • TLSConfig - set tls.Config options for things like client certificates or ignoring certificate validation

v0.3.0 Release

This release expands what you can do in regards to snapshots and repositories.

Breaking changes

• GetHealth API return type changed from []ClusterHealth to ClusterHealth - The array was a holdover from using the _cat API and didn't make logical sense as there is only one cluster health.

New APIs

• New struct Repository
• New struct IndexHealth, similar to the ClusterHealth struct, but scoped to an index
• New API func (c *Client) GetRepositories() ([]Repository, error)
  • List the snapshot repositories that are configured on the cluster
• New API func (c *Client) SnapshotAllIndices(repository string, snapshot string) error
  • Take a snapshot of all indices on the cluster
• New API func (c *Client) SnapshotIndices(repository string, snapshot string, indices []string) error
  • Take a snapshot of specific indices on the cluster
• New API func (c *Client) RestoreSnapshotIndices(repository string, snapshot string, indices []string, restoredIndexPrefix string) error
  • Restore specific indices of the named snapshot to the cluster

Changes

• Jdk added to Node struct - contains the Jdk version of the node
• ClusterHealth has two new fields
  • UnhealthIndices []IndexHealth - contains indices that are non-green status
  • HealthyIndices []IndexHealth - contains indices that are green status

Managing snapshots

This release adds two new functions around managing snapshots and repositories.

• func (c *Client) DeleteSnapshot(repository string, snapshot string) error

• func (c *Client) VerifyRepository(repository string) (bool, error)

Standardize vulcanizer API surface

Features:

• Client methods all return a specific struct type and an error.
