solr
A Solr client written in Go
Designed for Solr 8.5 (Should support earlier versions as well)
Provides clients for Solr's Request API, Schema API & Core Admin API
Currently supports only JSON and basic CRUDL actions.
Installation
go get -u github.com/mecenat/solr
Usage
To create a new solr Client you need first to create a Connection. To create a Connection you need the host location (e.g. http://localhost:8983), the core name, and a http client (e.g. http.DefaultClient). Sending your own client could be useful when you need to wrap the client with another service, for example if you want to use AWS's X-Ray service to trace your API's calls.
When using a single server:
package main
import "github.com/mecenat/solr"
func main() {
conn, err := solr.NewConnection("host", "core", http.DefaultClient)
if err != nil {
...
}
slr, err := solr.NewSingleClient(conn)
if err != nil {
...
}
When using a the Primary-Replica paradigm:
package main
import "github.com/mecenat/solr"
func main() {
primaryConn, err := solr.NewConnection("primaryHost", "core", http.DefaultClient)
if err != nil {
...
}
replicaConn, err := solr.NewConnection("replicaHost", "core", http.DefaultClient)
if err != nil {
...
}
slr, err := solr.NewPrimaryReplicaClient(primaryConn, replicaConn)
if err != nil {
...
}
Aside from the normal Connection you can you a RetryableConnection which implements Hashicorp's retryable HttpClient specifying the max timeout and provide that connection to the clients.
package main
import "github.com/mecenat/solr"
func main() {
retConn, err := solr.NewRetryableConnection("host", "core", http.DefaultClient, 500*time.Millisecond)
if err != nil {
...
}
slr, err := solr.NewSingleClient(retConn)
if err != nil {
...
}
To access Solr's Core Admin API you need to create a separate client as follows:
package main
import "github.com/mecenat/solr"
func main() {
ctx := context.Background()
ca, err := solr.NewCoreAdmin(ctx, "host", http.DefaultClient)
if err != nil {
...
}
To access Solr's Schema API you also need a separate client as follows:
package main
import "github.com/mecenat/solr"
func main() {
ctx := context.Background()
sa, err := solr.NewSchemaAPI(ctx, "host", "core", http.DefaultClient)
if err != nil {
...
}
