NineData Data Migration: Easily Achieve Data Migration from MySQL to Greenplum
MySQL has become the preferred choice for many enterprises due to its ease of use and extensive application support. However, for large-scale datasets, the query performance bottleneck of MySQL is exposed.
Greenplum is a data warehouse based on a massively parallel processing (MPP) architecture, compatible with SQL standards, and has strong data processing and real-time analysis capabilities, which just compensates for the query performance bottleneck of MySQL.
To effectively use Greenplum to process the large amount of data in MySQL, migrating data from MySQL to Greenplum is an effective way. However, due to the structural differences between the two databases, there are certain challenges in completing data migration:
High-Performance Replication: As a data warehouse, Greenplum does not support high-concurrency real-time DML writes very well, while MySQL, as the core business database of enterprises, generally has high-concurrency DML writes. How to achieve high-performance real-time incremental replication from MySQL to Greenplum is a great challenge.
Data Type Differences: There are differences in their numeric types, date and time types, string types, binary types, special types, etc., and they are not directly compatible.
Syntax Differences: Greenplum is based on PostgreSQL, so its SQL syntax is very similar to that of PostgreSQL, while MySQL's syntax may have differences, and the names or behaviors of some functions may be different.
Migration Solutions
Greenplum's Native Solution: It supports the use of the COPY command to load CSV format files containing MySQL data into Greenplum. However, due to the differences in data types between the two ends, it is necessary to manually create tables in Greenplum that are consistent with the structure of the source end, including column names, column types, column order, etc., while also paying attention to the mapping of data types. This will consume a lot of time and manpower when there is a large amount of data on the source end, and there is a high probability of data conversion errors.
Third-Party Migration Tools: They have a graphical interface and good compatibility, but their performance depends on the host running the tool, and performance bottlenecks are likely to occur when processing large data streams. At the same time, since most tools do not have alarm functions, problems may not be detected and handled in time, affecting business operations. In addition, third-party tools are generally expensive and not suitable for small and medium-sized enterprises.
