Store #

The store component of Thanos implements the Store API on top of historical data in an object storage bucket. It acts primarily as an API gateway and therefore does not need significant amounts of local disk space. It joins a Thanos cluster on startup and advertises the data it can access. It keeps a small amount of information about all remote blocks on local disk and keeps it in sync with the bucket. This data is generally safe to delete across restarts at the cost of increased startup times.

$ thanos store \
    --data-dir        "/local/state/data/dir" \
    --cluster.peers    "thanos-cluster.example.org" \
    --objstore.config-file "bucket.yml"

The content of bucket.yml:

type: GCS
config:
  bucket: example-bucket

In general about 1MB of local disk space is required per TSDB block stored in the object storage bucket.

                                 (StoreAPI). Make sure this address is routable
                                 from other components if you use gossip,
                                 'grpc-advertise-address' is empty and you
                                 require cross-node connection.

      --grpc-server-tls-client-ca=""  
                                 TLS CA to verify clients against. If no client
                                 CA is specified, there is no client
                                 verification on server side. (tls.NoClientCert)
      --http-address="0.0.0.0:10902"

                                 Explicit (external) ip:port address to
                                 advertise for gossip in gossip cluster. Used

                                 either <ip:port>, or <domain:port>. A lookup
                                 resolution is done only at the startup.
      --cluster.gossip-interval=<gossip interval>

                                 lowering this value (more frequent) gossip
                                 messages are propagated across the cluster more
                                 quickly at the expense of increased bandwidth.

                                 convergence speeds across larger clusters at
                                 the expense of increased bandwidth usage.

                                 accounting the latency differences between
                                 network types: local, lan, wan.
