Errors table
Users can choose to use local configure, based on their preferences, error tables as local or a global one, depending on their preferencesglobal ones.
Local error table
Users may apply `hoodie.write.error.table.global=false` (default) to Hudi writers such that the failed By default, if error table is enabled, it will be a local error table. Failed records will be written to a local Hudi table alongside with the target tableoriginal Hudi table with a suffix (configurable) like `_errors`.
Global error table
Users may apply To write to a global error table, users can configure `hoodie.write.error.table.base.path=<some file system path>` and `hoodie.write.error.table.global=true` to Hudi writers such that the failed records will be written to a global Hudi tablename=foobar`. If either of these 2 configs were set, error table is set to global mode and `hoodie.write.error.table.suffix` will be omitted.
Configurations

| hoodie.write.error.table.enabled | set to true to activate error table handling feature | false | ||
| hoodie.write.error.table.suffix | suffix for local error table name, stored alongside the target table. If the Hudi table is "foo", errored records will be saved to "foo_errors" at the same base dir as configured via `hoodie.base.path` | "_errors" | ||
