Types

type TiFlashRecorder

type TiFlashRecorder struct {
	// contains filtered or unexported fields
}

TiFlashRecorder records the information of TiFlash replicas during restoring. Because the limit of the current implementation, we add serval hooks to observe the information we need:

• Before full restore create tables: We record the tiflash replica information and remove the replica info. Because during PiTR restore, the transaction model would be broken, which breaks TiFlash too. We must make sure they won't be replicated to TiFlash during the whole PiTR procedure.
• After full restore created tables, generating rewrite rules: We perform the rewrite rule over our records. We trace table via table ID instead of table name so we can handle `RENAME` DDLs.
• When doing PiTR restore, after rewriting table info in meta key: We update the replica information
