MySQL dump partition | backup partition | restore partition

MySQL dump Partition and import partition: $ mysqldump --user=root --password=<code> \ -S/mysql/<db_name>/data/<db_name>.sock --set-gtid-purged=OFF - -no-create-info \ <db_name> <table_name> --where="datetime between 'YYYY-MM-DD'  and 'YYYY-MM-DD'"  \  > /mysql/backup/<partition_name>.sql Where data type is bigint for partition, it will dump DDL for table also: $ mysqldump -uroot -p -S/mysql/mysql.sock --set-gtid-purged=OFF  \ <db_name> <table_name> --where="ENDDATE" between '20200801000000' and '20201101000000' \  > /mysql/dump/<schema_name>.<table_name>.sql   Alter table and add partitions which are truncated: Note: In following case partition 2018_MAY and 2018_JUN were truncated, so we need to reorganize the partition which is just after the desired partition. ALTER TABLE <table_name> REORGANIZE PARTITION 2018_JUL INTO ( PARTITION 2018_MAY VALUES LESS TH
