Joe Blubaugh 5e4fd94413 Alerting: Write and Delete multiple alert instances. (#54072) ... Prior to this change, all alert instance writes and deletes happened individually, in their own database transaction. This change batches up writes or deletes for a given rule's evaluation loop into a single transaction before applying it. Before: ``` goos: darwin goarch: arm64 pkg: github.com/grafana/grafana/pkg/services/ngalert/store BenchmarkAlertInstanceOperations-8 398 2991381 ns/op 1133537 B/op 27703 allocs/op --- BENCH: BenchmarkAlertInstanceOperations-8 util.go:127: alert definition: {orgID: 1, UID: FovKXiRVzm} with title: "an alert definition FTvFXmRVkz" interval: 60 created util.go:127: alert definition: {orgID: 1, UID: foDFXmRVkm} with title: "an alert definition fovFXmRVkz" interval: 60 created util.go:127: alert definition: {orgID: 1, UID: VQvFuigVkm} with title: "an alert definition VwDKXmR4kz" interval: 60 created PASS ok github.com/grafana/grafana/pkg/services/ngalert/store 1.619s ``` After: ``` goos: darwin goarch: arm64 pkg: github.com/grafana/grafana/pkg/services/ngalert/store BenchmarkAlertInstanceOperations-8 1440 816484 ns/op 352297 B/op 6529 allocs/op --- BENCH: BenchmarkAlertInstanceOperations-8 util.go:127: alert definition: {orgID: 1, UID: 302r_igVzm} with title: "an alert definition q0h9lmR4zz" interval: 60 created util.go:127: alert definition: {orgID: 1, UID: 71hrlmR4km} with title: "an alert definition nJ29_mR4zz" interval: 60 created util.go:127: alert definition: {orgID: 1, UID: Cahr_mR4zm} with title: "an alert definition ja2rlmg4zz" interval: 60 created PASS ok github.com/grafana/grafana/pkg/services/ngalert/store 1.383s ``` So we cut time by about 75% and memory allocations by about 60% when storing and deleting 100 instances. This change also updates some of our tests so that they run successfully against postgreSQL - we were using random Int64s, but postgres integers, which our tables use, max out at 2^31-1		3 years ago
