go-solr

solr go client from Sendgrid

Usage

To start the client

solrzk := solr.NewSolrZK(...)
solrzk.Listen()
solrhttp := solr.NewSolrHttp(solrzk)
solrClient := solr.NewSolrHttpRetrier(solrhttp)

The Read and Update methods take a node list use the SolrLocator interface to return a node list

locator := solr.GetSolrLocator(solr.NewSolrZK(...))
type SolrLocator interface {
	GetLeaders(docID string) ([]string, error)
	GetReplicaUris() ([]string, error)
	GetReplicasFromRoute(route string) ([]string, error)
	GetLeadersAndReplicas(docID string) ([]string, error)
}

To make requests

solrClient.Read(locator.GetReplicasFromRoute("shard!"),solr.FilterQuery("myfield:test"),solr.Route("shardkey!"))

To make updates

solrClient.Update(locator.GetLeadersAndReplicas("{anydocidtoroute}"),collectionName,callsSolrJsonDocs, docsMap)

Tests

  1. docker-compose up
  2. docker-compose run gotests bash
  3. go test
