+## Description
+
+Designed for transform parsed message at the end of the pipeline
+1. [th2-read-db which pulls Oracle redo log](https://github.com/th2-net/th2-read-db/tree/dev-2/oracle-log-miner.md)
+2. [th2-codec-csv](https://github.com/th2-net/th2-codec-csv)
+
+The codec (transformer) is based on [th2-codec](https://github.com/th2-net/th2-codec). You can find additional information [here](https://github.com/th2-net/th2-codec/blob/master/README.md)
+
+## Decoding (transformation)
+
+The codec parses a SQL query in the `SQL_REDO` field to extract column and value pairs and appends them into an output message.
+The `OPERATION`, `SQL_REDO`, `ROW_ID`, `TIMESTAMP`, `TABLE_NAME` fields are required in source parsed message for transformation otherwise `th2-codec-error` message is produced 
+
+### Parser workflow:
+1. detects type of query by the `OPERATION` field. 
+Currently, the `INSERT` / `UPDATE` / `DELETE` values are supported.
+2. parses a value of the `SQL_REDO` field as SQL query.
+3. creates an empty parsed message and copies the whole metadata from the source message.
+4. appends parsed columns and values to the new parsed message. 
+Each field will have a prefix specified in the `columnPrefix` option.
+5. copies fields specified the `saveColumns` option from source to new parsed message.
+
+### Transform example:
+
+source parsed message body
+```json
+{
+  "SCN": 3627285,
+  "TIMESTAMP": "06-Dec-2023 08:54:31",
+  "OPERATION": "UPDATE",
+  "TABLE_NAME": "EMPLOYEE",
+  "ROW_ID": "AAASt5AAHAAAAFcAAA",
+  "SQL_REDO": "update \"<user>\".\"EMPLOYEE\" set \"SAVINGS\" = '10' where \"SAVINGS\" = '1' and ROWID = 'AAASt5AAHAAAAFcAAA';"
+}
+```
+
+outgoing parsed message body after transform with default configuration
+```json
+{
+  "TIMESTAMP": "06-Dec-2023 08:54:31",
+  "OPERATION": "UPDATE",
+  "TABLE_NAME": "EMPLOYEE",
+  "ROW_ID": "AAASt5AAHAAAAFcAAA",
+  "SQL_REDO": "update \"<user>\".\"EMPLOYEE\" set \"SAVINGS\" = '10' where \"SAVINGS\" = '1' and ROWID = 'AAASt5AAHAAAAFcAAA';",
+  "th2_SAVINGS": "10"
+}
+```
+
+## Encode
+
+This operation isn't support.
+
+## Settings
+
+Oracle log miner codec (transformer) has the following parameters:
+```yaml
+columnPrefix: 'th2_'
+saveColumns: [ OPERATION, SQL_REDO, ROW_ID, TIMESTAMP, TABLE_NAME ]
+```
+
+**columnPrefix** - prefix for parsed columns.
+**saveColumns** - set of column names to copy from source message.
+All columns which log miner allow to select are described in the [document](https://docs.oracle.com/en/database/oracle/oracle-database/19/refrn/V-LOGMNR_CONTENTS.html#GUID-B9196942-07BF-4935-B603-FA875064F5C3)
