配置文件模板
hbase节点信息
可配可不配,不配置的话直接使用hbase_client.py内的类,自行传入相关信息即可
pro: # 正式环境ec, thrift
host: 192.168.xx.xx # 失效
port: 9090
dev: # 开发环境, thrift
host: 192.168.xx.xx
host_name: xx-xx-xx
port: 9090
示例
import pandas as pd
from dm_hbase.hbase_client import HBaseClient
connection = HBaseClient(
host='xxx.xxx.xx.xx',
port=9090,
env='test' # 2022-11-15新增, env参数支持'test'或者'prd', 默认为'test'
)
connection.build_pool()
# 查看当前库中所有表
connection.show_tables()
# 查表
connection.scan_tables(
table_name='xxx:xxxx',
limit=10
)
# 查列族
connection.get_families('xxx:xxxx')
# 查分区
connection.get_regions('xxx:xxx')
# 插入数据
connection.insert(
table_name='xxx:xxx',
datas={row_key: {'column_family:feature': value}}
batch_size=1000
)
# 以dataframe形式插入数据
df = pd.read_csv('xxx.csv')
connection.insert_df(
table_name='xxx:xxx',
df=df,
rowkeys_col='xxx',
batch_size=1000
)
