DBZ-4027 Initial refactoring of signal feature
When the connector starts for the first time with initial snapshot record with read operation will be created. In this phase the ExtractChangedRecordState will produce no headers and since HeaderToValue was not skipping record without headers the cache of the new schema will be created only with the old fields.
In DBZ-6225, it was identified that the schema type associated with TINYINT(1)
and BOOLEAN data types wasn't consistent. This converter implementation will
always emit BOOLEAN data types as INT16, similar to TINYINT(1).
In DBZ-6226, it was identified that the schema type associated with REAL data
types wasn't consistent, emitted as FLOAT64 during snapshot and FLOAT32 in
the streaming phase. This converter implementation will always emit such types
as FLOAT64 for consistency.
In DBZ-6231, during streaming the DDL parser will get the column type as the
literal type supplied by the user's DDL, i.e. NCHAR or NVARCHAR but when the
DDL is sourced from SHOW CREATE TABLE, MySQL returns these columns as types
of CHAR/VARCHAR but with a character set. By passing the character_set in
the schema consistency, we can deduce nationalized vs non-nationalized.
For tables that have a composite Primary Key, SQL queries for incremental snapshot perform bad. This change allows to provide a surrogate key that will be used for the queries. The key should be unique in order for the snapshot to guarantee consistency.
If the table contains back slash, which is ANSI SQL escape chracter,
in its name, querying column metadata would fail in some cases (*)
which would result into NPE. Fix table name before the query and
escape escape character if the table name contains it.
Default backslash works for all currently supported databases as it's
ANSI SQL standard,
(*) everything works when we collect column metadata for all tables,
i.e. when there are no excluded tables
