Exporting Data
TDSQL for MySQL supports exporting data with mysqldump. Before export, you need to set the
net_write_timeout parameter (set global net_write_timeout=28800) in the TDSQL for MySQL Console. Note that command line utilities are not authorized by TDSQL for MySQL, so you can set the parameter only in the console.mysqldump --compact --single-transaction --no-create-info -c db_name table_name -utest -h10.xx.xx.34 -P3336 -ptest123
Note:
The
db and table parameters should be specified based on the actual situation. If the exported data is to be imported into another set of TDSQL for MySQL environment, the -c option must be added.Export account needs to have
select on *.* permissions.Importing Data
TDSQL for MySQL provides a professional tool to import data specified by
load data outfile. This tool shards a source file into multiple files according to the shardkey routing rules, and passes each file through to the corresponding backend database.[tdengine@TENCENT64 ~/]$./load_dataformat:./load_data mode0/mode1 proxy_host proxy_port user password db_table shardkey_index file field_terminate filed_enclosedexample:./load_data mode1 10.xx.xx.10 3336 test test123 shard.table 1 '/tmp/datafile' ' ' ''
Note:
The source file must use '\\n' as a line break.
mode0 means that the source file is sharded but will not be imported, which is usually used for debugging. To import data, use mode1.shardkey_index starts from 0. If the shardkey is the second field, shardkey_index should be 1.
