These provide logical copies of the file system at a given point in time, without requiring a physical copy of the entire file system. Full Versus Incremental Backups A full backup includes all data managed by a MySQL server at a given point in time. An incremental backup consists of the changes made to the data during a given time span (from one point in time to ...

These events bring databases up to date from the point of the backup. For more information about the binary log and recovery operations, see Section 7.5, “Point-in-Time (Incremental) Recovery Using the Binary Log”. At that point, mysqld writes ... The binary log contains “events” that describe database changes such as table creation operations or changes to table ...

To migrate calls from using geometry arguments to using WKB arguments, follow these guidelines: Rewrite constructs such as ST_GeomFromWKB(Point(0, 0)) as Point(0, 0). Rewrite constructs such as ST_GeomFromWKB(Point(0, 0), 4326) as ST_SRID(Point(0, ... These functions take as arguments a BLOB containing a Well-Known Binary (WKB) representation and, optionally, a spatial reference system identifier ...
