clickhouse output

It sends the event batches to Clickhouse database using Native format and Native protocol.

File.d uses low level Go client - ch-go to provide these features.

Config params

addresses []Address required

TCP Clickhouse addresses, e.g.: 127.0.0.1:9000. Check the insert_strategy to find out how File.d will behave with a list of addresses.

Accepts strings or objects, e.g.:

addresses:
  - 127.0.0.1:9000 # the same as {addr:'127.0.0.1:9000',weight:1}
  - addr: 127.0.0.1:9001
    weight: 2

When some addresses get weight greater than 1 and round_robin insert strategy is used, it works as classical weighted round robin. Given {(a_1,w_1),(a_1,w_1),...,{a_n,w_n}}, where a_i is the ith address and w_i is the ith address' weight, requests are sent in order: w_1 times to a_1, w_2 times to a_2, ..., w_n times to a_n, w_1 times to a_1 and so on.


insert_strategy string default=round_robin options=round_robin|in_order

If more than one addresses are set, File.d will insert batches depends on the strategy: round_robin - File.d will send requests in the round-robin order. in_order - File.d will send requests starting from the first address, ending with the number of retries.


ca_cert string

CA certificate in PEM encoding. This can be a path or the content of the certificate.


database string default=default

Clickhouse database name to search the table.


user string default=default

Clickhouse database user.


password string

Clickhouse database password.


quota_key string

Clickhouse quota key. https://clickhouse.com/docs/en/operations/quotas


table string required

Clickhouse target table.


columns []Column required

Clickhouse table columns. Each column must contain name and type. File.d supports next data types:

  • Signed and unsigned integers from 8 to 64 bits. If you set 128-256 bits - File.d will cast the number to the int64.
  • DateTime, DateTime64
  • String
  • Enum8, Enum16
  • Bool
  • Nullable
  • IPv4, IPv6
  • LowCardinality(String)
  • Array(String)

If you need more types, please, create an issue.


strict_types bool default=false

If true, file.d fails when types are mismatched.

If false, file.d will cast any JSON type to the column type.

For example, if strict_types is false and an event value is a Number, but the column type is a Bool, the Number will be converted to the "true" if the value is "1". But if the value is an Object and the column is an Int File.d converts the Object to "0" to prevent fall.

In the non-strict mode, for String and Array(String) columns the value will be encoded to JSON.

If the strict mode is enabled file.d fails (exit with code 1) in above examples.


retry int default=10

Retries of insertion. If File.d cannot insert for this number of attempts, File.d will fall with non-zero exit code or skip message (see fatal_on_failed_insert).


fatal_on_failed_insert bool default=false

After an insert error, fall with a non-zero exit code or not Experimental feature


clickhouse_settings Settings

Additional settings to the Clickhouse. Settings list: https://clickhouse.com/docs/en/operations/settings/settings


retention cfg.Duration default=50ms

Retention milliseconds for retry to DB.


retention_exponentially_multiplier int default=2

Multiplier for exponential increase of retention between retries


insert_timeout cfg.Duration default=10s

Timeout for each insert request.


max_conns cfg.Expression default=gomaxprocs*4

Max connections in the connection pool.


min_conns cfg.Expression default=gomaxprocs*1

Min connections in the connection pool.


max_conn_lifetime cfg.Duration default=30m

How long a connection lives before it is killed and recreated.


max_conn_idle_time cfg.Duration default=5m

How long an unused connection lives before it is killed.


health_check_period cfg.Duration default=1m

How often to check that idle connections is time to kill.


workers_count cfg.Expression default=gomaxprocs*4

How much workers will be instantiated to send batches. It also configures the amount of minimum and maximum number of database connections.


batch_size cfg.Expression default=capacity/4

Maximum quantity of events to pack into one batch.


batch_size_bytes cfg.Expression default=0

A minimum size of events in a batch to send. If both batch_size and batch_size_bytes are set, they will work together.


batch_flush_timeout cfg.Duration default=200ms

After this timeout batch will be sent even if batch isn't completed.
