Performance Schema Replication Tables The list of TLS protocol versions that are permitted by the replica for the replication connection. For TLS version information, see Section 6.3.2, “Encrypted Connection TLS Protocols and Ciphers” . ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_TLS_VERSION ,  CHANGE MASTER TO  option: MASTER_TLS_VERSION ) The list of ciphersuites that are permitted by the replica for the replication connection. For TLS ciphersuite information, see Section 6.3.2, “Encrypted Connection TLS Protocols and Ciphers” . ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_TLS_CIPHERSUITES ,  CHANGE MASTER TO  option: MASTER_TLS_CIPHERSUITES ) • TLS_CIPHERSUITES • PUBLIC_KEY_PATH The path name to a file containing a replica-side copy of the public key required by the source for RSA key pair-based password exchange. The file must be in PEM format. This column applies to replicas that authenticate with the  sha256_password  or  caching_sha2_password  authentication plugin. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_PUBLIC_KEY_PATH ,  CHANGE MASTER TO option:  MASTER_PUBLIC_KEY_PATH ) If  PUBLIC_KEY_PATH  is given and specifies a valid public key file, it takes precedence over GET_PUBLIC_KEY . • GET_PUBLIC_KEY Whether to request from the source the public key required for RSA key pair-based password exchange. This column applies to replicas that authenticate with the  caching_sha2_password authentication plugin. For that plugin, the source does not send the public key unless requested. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_GET_PUBLIC_KEY ,  CHANGE MASTER TO option:  MASTER_GET_PUBLIC_KEY ) If  PUBLIC_KEY_PATH  is given and specifies a valid public key file, it takes precedence over GET_PUBLIC_KEY . The network namespace name; empty if the connection uses the default (global) namespace. For information about network namespaces, see Section 5.1.14, “Network Namespace Support” . This column was added in MySQL 8.0.22. • NETWORK_NAMESPACE • COMPRESSION_ALGORITHMS • ZSTD_COMPRESSION_LEVEL The permitted compression algorithms for connections to the source. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_COMPRESSION_ALGORITHMS ,  CHANGE MASTER TO  option: MASTER_COMPRESSION_ALGORITHMS ) For more information, see Section 4.2.8, “Connection Compression Control” . This column was added in MySQL 8.0.18. The compression level to use for connections to the source that use the  zstd  compression algorithm. ( CHANGE REPLICATION SOURCE TO  option:  SOURCE_ZSTD_COMPRESSION_LEVEL ,  CHANGE MASTER TO  option:  MASTER_ZSTD_COMPRESSION_LEVEL ) For more information, see Section 4.2.8, “Connection Compression Control” . 5002
