This section describes replication between MySQL servers based on the binary log file.
Eventually this causes replication to break. 1 Binary Log File Position Based Replication Configuration Overview.
However, eventually people start creating new tables, modifying existing tables on the master server which is located in the local data center and those DDL changes are replicated to the database for which I have set all the tables to BLACKHOLE. Then I change all the tables for the databases I don't want to replicate to BLACKHOLE. There are two ways to skip errors: 1.1 Skip a specified number of transactions: mysql>stop slave mysql>SET GLOBAL SQLSLAVESKIPCOUNTER 1 Skip a transaction mysql>start slave 1. What I do is export and import all the tables for all the database into Aurora. 16.1.7.3.2.1 Skipping Transactions With SET GLOBAL sqlslaveskipcounter 16.1.7.3.2. When you use the INSERT statement to add multiple rows to a table and if an error occurs during the processing, MySQL terminates the statement and. There might be hundreds of databases on a single server and the client only want to replicate one of them into Aurora. When replicating from the local data center to Aurora, the client does not always want to replicate every single database into Aurora.
#MYSQL SKIP COUNTER 1 HOW TO#
Key functions: The following four functions correspond to four events SKIP, and how to SKIP. If youd like to skip two queries, youd use SET GLOBAL SQLSLAVESKIPCOUNTER 2 instead and so on. We tell the slave to simply skip the invalid SQL query: mysql> SET GLOBAL SQLSLAVESKIPCOUNTER 1 This tells the slave to skip one query (which is the invalid one that caused the replication to stop). case 2: set global sqlslaveskipcounter10 start slave. Fixing the problem is actually quite easy. case 1: set global sqlslaveskipcounter1 start slave. One of the semi frustrating things I have to deal with is the widespread use of the BLACKHOLE storage engine in Aurora by my client. Because of the primary key conflict, Slave stops recovery. However, periodically some statement breaks replication and I have to skip replication if it is safe to do so. If their local data center were to go down, they have all their data in Aurora. The client has thousands of databases that are being replicated from their local data center into Aurora. I have a client that uses Aurora as a disaster recovery "site". You don't have to stop and start replication but do need to use the stored procedure provided by the Aurora folks.
