示例1: compact
// compact compacts etcd store and returns current rev.
// It will return the current compact time and global revision if no error occurred.
// Note that CAS fail will not incur any error.
func compact(ctx context.Context, client *clientv3.Client, t, rev int64) (int64, int64, error) {
resp, err := client.KV.Txn(ctx).If(
clientv3.Compare(clientv3.Version(compactRevKey), "=", t),
).Then(
clientv3.OpPut(compactRevKey, strconv.FormatInt(rev, 10)), // Expect side effect: increment Version
).Else(
clientv3.OpGet(compactRevKey),
).Commit()
if err != nil {
return t, rev, err
}
curRev := resp.Header.Revision
if !resp.Succeeded {
curTime := resp.Responses[0].GetResponseRange().Kvs[0].Version
return curTime, curRev, nil
}
curTime := t + 1
if rev == 0 {
// We don't compact on bootstrap.
return curTime, curRev, nil
}
if _, err = client.Compact(ctx, rev); err != nil {
return curTime, curRev, err
}
glog.Infof("etcd: compacted rev (%d), endpoints (%v)", rev, client.Endpoints())
return curTime, curRev, nil
}示例2: compact
// compact compacts etcd store and returns current rev.
// If it couldn't get current revision, the old rev will be returned.
func compact(ctx context.Context, client *clientv3.Client, oldRev int64) (int64, error) {
resp, err := client.Get(ctx, "/")
if err != nil {
return oldRev, err
}
curRev := resp.Header.Revision
if oldRev == 0 {
return curRev, nil
}
err = client.Compact(ctx, oldRev)
if err != nil {
return curRev, err
}
return curRev, nil
}示例3: compact
// compact compacts etcd store and returns current rev.
// If it couldn't get current revision, the old rev will be returned.
func compact(ctx context.Context, client *clientv3.Client, oldRev int64) (int64, error) {
resp, err := client.Get(ctx, "/")
if err != nil {
return oldRev, err
}
curRev := resp.Header.Revision
if oldRev == 0 {
return curRev, nil
}
err = client.Compact(ctx, oldRev)
if err != nil {
return curRev, err
}
