Module mz_mysql_util::schemas

Structs

• InfoSchema
• MySqlTableSchema
  A representation of the raw schema info for a table from MySQL
• QualifiedTableRef
  A reference to a table in a schema/database

Enums

• SchemaRequest
  Request for table schemas from MySQL

Constants

• INFO_SCHEMA_COLS 🔒
  Helper for querying information_schema.columns

Statics

• ENUM_VAL_REGEX 🔒
• SYSTEM_SCHEMAS
  Built-in system schemas that should be ignored when querying for user-defined tables since they contain dozens of built-in system tables that are likely not needed.

Functions

• enum_vals_from_column_type 🔒
  Parse the enum values from a column_type value on an enum column, which is a string like “enum(‘apple’,‘banana’,‘cher,ry’,‘ora’‘nge’)” We need to handle the case where the enum value itself contains a comma or a single quote (escaped with another quote), so we use a regex to do so
• parse_as_text_column 🔒
  Parse the specified column as a TEXT COLUMN. We only support the set of types that are represented as an encoded-string in both the mysql-common binary query response and binlog event representation, OR types that we’ve added explicit casting support for.
• parse_data_type 🔒
• schema_info
  Retrieve the tables and column descriptions for tables in the given schemas.
