Jaeger Storage Plugin -> PostgreSQL

This is the repository that contains PostgreSQL Storage gRPC plugin for Jaeger.

IMPORTANT: This plugin is still under development. We are using it internally already but the way we store data in PostgreSQL can change based on what do we learn about the data structure!

Compile

In order to compile the plugin from source code you can use go build:

CGO_ENABLED=0 go build ./cmd/jaeger-pg-store/

Start

In order to start plugin just tell jaeger the path to a config compiled plugin (password can be passed also as ENV: DB_PASSWORD).

jaeger-all-in-one --grpc-storage-plugin.binary=./jaeger-pg-store --grpc-storage-plugin.configuration-file=./config-example.yaml

Tables

This plugins create tables if they not exist:

• spans
• span_logs
• span_refs
• operations
• services

License

The PostgreSQL Storage gRPC Plugin for Jaeger is an MIT licensed open source project.

jaeger-postgresql's Issues

Remove whereBuilder

I was browsing the code and noticed this stuct. It does not seem to be used, so I recommend removing it because it is vulnerable to SQL injection:

jaeger-postgresql/pgstore/mapping.go

Lines 5 to 16 in b648037

	type whereBuilder struct {
	where string
	params []interface{}
	}
	func (r *whereBuilder) andWhere(param interface{}, where string) {
	if len(r.where) > 0 {
	r.where += " AND "
	}
	r.where += where
	r.params = append(r.params, param)
	}
