- 8. MySQL Shell Utilities Shell utility Backup Restore Other Table Export Utility Dump Utility Table Import Utility Dump Loading Utility JSON Import Utility Upgrade Checker Utility
- 10. Avoid data corruption Unwanted downtime extention Safe migration with proper pre-checks Upgrade Checker Utility - Purpose
- 11. Checks compatibility on server migration 5.7 to 8.0 Reserved keywords Supported variables (config - Shell 8.0.16 & global) Specific version check (Shell - 8.0.13) Upgrade Checker Utility
- 12. targetVersion - MySQL version to check the compactibility for upgrade configPath - Config file path outputFormat - TEXT (Default), JSON Upgrade Checker Utility - Notable options
- 15. Faster table export Controlled Export to avoid load Rough estimation on completion Table Export Utility - Purpose
- 16. Table export with parallel thread Progress monitor Compression - None (Default), gzip, zstd Supported output format - CSV, TSV (Default) Output to local or oracle cloud infra Table Export Utility
- 17. maxRate - bytes per second per thread compression - gzip, zstd , none(default) dialect - Export format - csv|csv-unix|tsv Table Export Utility - Notable options
- 19. Parallel Table Import Utility
- 20. Import the data with parallel thread Controlled import Replace the duplicate values of primary key/ unique Mutiple files at a time from different server Parallel Table Import Utility - Purpose
- 21. Loading the table with a parallel thread Progress tracking Can restore compressed ( > Shell - 8.0.22 ) Restore multiple file to single table ( > Shell - 8.0.23 shell version) Option to avoid duplicate entry failure. Parallel Table Import Utility
- 22. threads - No of thread for restoring maxRate - bytes per second per thread replaceDuplicates - Replace existing row of PK/UK (Default - yes) skipRows - Skip the no of row from the begining of file. Parallel Table Import Utility - Notable options
- 23. Parallel Table Import Utility Syntax :
- 24. Parallel Table Import Utility Duplicate entry :
- 25. Dump Utility
- 26. Dump Utility Instance dump Dump utility Schema dump Table dump
- 27. Exporting the data with parallel thread Dry-run before exporting Compatability checks Default compression Dump utility - Purpose
- 28. Object names in the instance or schema must be in the latin1 or utf8 characterset. Data consistency is guaranteed only for tables that use the InnoDB storage engine. Group Replication, primary keys are required on every table. Dump Utility - Notable requirement
- 29. dryRun - Information about what will be dumped threads - Thread used to export data maxRate - The maximum number of bytes per second per thread. consistent - Lock the instance while taking backup chunking - Split the data for each table into multiple files compression - No , gzip , zstd (default) Dump Utility - Notable options
- 30. Dump utility - Instance dump
- 31. Dump utility - Schema dump
- 32. Dump utility - Table dump
- 34. Speed the restoration by a parallel thread. Ignore the index at the target to speed up restoration. Need to restore the only specified schema from the full dump. Dump loading utility - Purpose
- 35. Restore the dump data with parallel thread ( > Shell - 8.0.21 ) Restore only the required table or schema Analyze table post restore Index creation post-restoration to boost loading (Default - Full text index) Dump loading utility
- 36. threads - No.of thread used to restore the data backgroundThreads - No.of thread used to fetch data loadIndexes - Restore index at target (Default - true) deferTableIndexes - Index creation post restoration. Dump loading utility - Notable options
- 39. Migration of Mongo DB to MySQL Create the table structure based on JSON JSON import Utility - Purpose
- 40. Import both JSON and BJSON to MySQL ( > Shell - 8.0.13 ) Import to an existing table or new table The default column name is doc Auto conversion of BJSON to JSON ( > Shell - 8.0.14 ) JSON import Utility
- 41. tableColumn - Columns need to be restored. convertBsonTypes - Convertion is required (Default - true) JSON import Utility - Notable options
