zookeeper_quorum [string]

The zookeeper cluster host of hbase, example: "hadoop001:2181,hadoop002:2181,hadoop003:2181"

table [string]

The table name you want to write, example: "seatunnel"

rowkey_column [list]

The column name list of row keys, example: ["id", "uuid"]

family_name [config]

The family name mapping of fields. For example the row from upstream like the following shown:

id	name	age
1	tyrantlucifer	27

id as the row key and other fields written to the different families, you can assign

family_name { name = "info1" age = "info2" }

this means that name will be written to the family info1 and the age will be written to the family info2

if you want other fields written to the same family, you can assign

family_name { all_columns = "info" }

this means that all fields will be written to the family info

rowkey_delimiter [string]

The delimiter of joining multi row keys, default ""

version_column [string]

The version column name, you can use it to assign timestamp for hbase record

null_mode [double]

The mode of writing null value, support [skip, empty], default skip

• skip: When the field is null, connector will not write this field to hbase
• empty: When the field is null, connector will write generate empty value for this field

wal_write [boolean]

The wal log write flag, default false

write_buffer_size [int]

The write buffer size of hbase client, default 8 * 1024 * 1024

encoding [string]

ttl [long]

Hbase writes data TTL time, the default is based on the TTL set in the table, unit: milliseconds

Sink plugin common parameters, please refer to Sink Common Options for details

Example

Hbase {
  zookeeper_quorum = "hadoop001:2181,hadoop002:2181,hadoop003:2181"
  table = "seatunnel_test"
  rowkey_column = ["name"]
  family_name {
    all_columns = seatunnel
  }
}

Writes To The Specified Column Family

Hbase {
  zookeeper_quorum = "hbase_e2e:2181"
  table = "assign_cf_table"
  rowkey_column = ["id"]
  family_name {
    c_double = "cf1"
    c_bigint = "cf2"
  }
}
