NDB_IMPORT(1)

NAME
ndb_import - Import CSV data into NDB

SYNOPSIS

ndb_import options

DESCRIPTION

ndb_import imports CSV-formatted data, such as that produced by mysqldump --tab, directly into NDB using the NDB API. ndb_import requires a connection to an NDB management server (ndb_mgmd) to function; it does not require a connection to a MySQL Server. Usage

    ndb_import db_name file_name options

ndb_import requires two arguments. db_name is the name of the database where the table into which to import the data is found; file_name is the name of the CSV file from which to read the data; this must include the path to this file if it is not in the current directory. The name of the file must match that of the table; the file's extension, if any, is not taken into consideration. Options supported by ndb_import include those for specifying field separators, escapes, and line terminators, and are described later in this section. ndb_import must be able to connect to an NDB Cluster management server; for this reason, there must be an unused [api] slot in the cluster config.ini file.

To duplicate an existing table that uses a different storage engine, such as InnoDB, as an NDB table, use the mysql client to perform a SELECT INTO OUTFILE statement to export the existing table to a CSV file, then to execute a CREATE TABLE LIKE statement to create a new table having the same structure as the existing table, then perform ALTER TABLE ... ENGINE=NDB on the new table; after this, from the system shell, invoke ndb_import to load the data into the new NDB table. For example, an existing InnoDB table named myinnodb_table in a database named myinnodb can be exported into an NDB table named myndb_table in a database named myndb as shown here, assuming that you are already logged in as a MySQL user with the appropriate privileges:

    1. In the mysql client:

        mysql> USE myinnodb;
        mysql> SELECT * INTO OUTFILE '/tmp/myndb_table.csv'
             >  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\'
             >  LINES TERMINATED BY '\n'
             >  FROM myinnodbtable;
        mysql> CREATE DATABASE myndb;
        mysql> USE myndb;
        mysql> CREATE TABLE myndb_table LIKE myinnodb.myinnodb_table;
        mysql> ALTER TABLE myndb_table ENGINE=NDB;
        mysql> EXIT;
        Bye
        shell>

    Once the target database and table have been created, a running mysqld is no longer required. You can stop it using mysqladmin shutdown or another method before proceeding, if you wish.

    2. In the system shell:

        # if you are not already in the MySQL bin directory:
        shell> cd path-to-mysql-bin-dir
        shell> ndb_import myndb /tmp/myndb_table.csv --fields-optionally-enclosed-by='"' \
            --fields-terminated-by="," --fields-escaped-by='\\'

    The output should resemble what is shown here:

        job-1 import myndb.myndb_table from /tmp/myndb_table.csv
        job-1 [running] import myndb.myndb_table from /tmp/myndb_table.csv
        job-1 [success] import myndb.myndb_table from /tmp/myndb_table.csv
        job-1 imported 19984 rows in 0h0m9s at 2277 rows/s
        jobs summary: defined: 1 run: 1 with success: 1 with failure: 0
        shell>
