…FAILS When a chunk file has more data than would fit in a single transaction, as limited by configurations like group_replication_transaction_size_limit or max_binlog_cache_size, the LOAD DATA would fail with an error. The problem is compounded by the fact that certain tables can end up with chunks that are much larger than the specified bytesPerChunk value, no matter how small that value is set. This patch works around that by flushing out chunks during load (by prematurely ending the LOAD DATA operation at a whole row boundary), whenever the number of bytes sent is about to go over bytesPerChunk * 1.5 bytes. LOAD DATA is then re-issued to load the rest of the file. Also: Store bytesPerChunk used during dump in the dump metadata, along with the uncompressed chunk file sizes in @.done.json Increased default bytesPerChunk to 64M since impact of over-sized chunks is now reduced, while still accounting for relatively small values of group_replication_transaction_size_limit.

README
Copyright (c) 2016, 2020, Oracle and/or its affiliates. This is a release of MySQL Shell (part of MySQL Server), an interactive JavaScript, Python and SQL console interface, supporting development and administration for the MySQL Server. It provides built in scriptable APIs that support the creation and management of MySQL InnoDB clusters, as well as a modern fluent CRUD API for the MySQL Document Store. Connections to MySQL server can use X Protocol or classic MySQL protocol. The AdminAPI enables you to work with MySQL InnoDB cluster, providing an integrated solution for high availability and scalability using InnoDB based MySQL databases, without requiring advanced MySQL expertise. For more information about how to configure and work with MySQL InnoDB cluster see https://dev.mysql.com/doc/refman/en/mysql-innodb-cluster-userguide.html. The Document Store X DevAPI enables developers and DBAs to create "schema-less" JSON document collections and perform Create, Update, Read, Delete (CRUD) operations on those collections without in depth knowledge of the SQL language. Additionally, MySQL Shell (part of MySQL Server) provides partial compatibility with the mysql command line client by supporting many of the same command line options. As with the mysql command line, MySQL Shell (part of MySQL Server) can also be used to connect to and send SQL commands to MySQL server using the classic MySQL protocol. For more information about how to use MySQL Shell see https://dev.mysql.com/doc/mysql-shell/8.0/en/ For more information about how to configure and work with an InnoDB cluster see https://dev.mysql.com/doc/refman/en/mysql-innodb-cluster-userguide.html For more information about how to use X DevAPI and the MySQL Document Store see https://dev.mysql.com/doc/refman/en/document-store.html For JavaScript API documentation, see: https://dev.mysql.com/doc/dev/mysqlsh-api-javascript/8.0/ For Python API documentation, see: https://dev.mysql.com/doc/dev/mysqlsh-api-python/8.0/ For full documentation on MySQL Server, MySQL Shell and related topics, see: https://dev.mysql.com/doc/refman/en/ If you want to write applications that use the the CRUD based X DevAPI use the latest MySQL Connectors for your language of choice.
