AWS Athena , Hive & Presto Cheat sheet

This is a quick “Cut the bullshit and give me what I Need” blog.

Your biggest problem in AWS Athena – is how to create table 🙂

Create table with separator pipe separator

CREATE   EXTERNAL TABLE logs (
    id STRING,
    query STRING
)
    ROW FORMAT DELIMITED
      FIELDS TERMINATED BY '|'
      ESCAPED BY '\\'
      LINES TERMINATED BY '\n'
    LOCATION 's3://myBucket/logs';

create table with CSV SERDE

CREATE EXTERNAL TABLE IF NOT EXISTS logs(
 `date` string,
 `query` string 
 )

 ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
 LOCATION 's3://omidongage/logs'

Create table with partition and parquet

CREATE EXTERNAL TABLE users (
first string,
last string,
username string
)
PARTITIONED BY (id string)
STORED AS parquet
LOCATION 's3://bucket/folder/'

create table on local HDFS using pipe separator with header skip

create table lineitem (
    l_orderkey    BIGINT ,
    l_partkey     BIGINT ,
    l_suppkey     BIGINT ,
    l_linenumber  BIGINT ,
    l_quantity    DOUBLE ,
    l_extendedprice  DOUBLE ,
    l_discount    DOUBLE ,
    l_tax         DOUBLE ,
    l_returnflag  CHAR(1) ,
    l_linestatus  CHAR(1) ,
    l_shipdate    DATE ,
    l_commitdate  DATE ,
    l_receiptdate DATE,
    l_shipinstruct CHAR(25) ,
    l_shipmode     CHAR(10) ,
    l_comment      VARCHAR(44) 
)
row format delimited

tblproperties ("skip.header.line.count"="1");
