It means that the plugin have access to tuples produced by INSERT and UPDATE. Also, UPDATE/DELETE old row versions can be accessed depending on the configured replica identity. Changes can be consumed using the streaming protocol (logical replication slots) or by a special SQL API. + +**format version 1** produces a JSON object per transaction. All of the new/old tuples are available in the JSON object. Also, there are options to include properties such as transaction timestamp, schema-qualified, data types, and transaction ids. + +**format version 2** produces a JSON object per tuple. Optional JSON object for beginning and end of transaction. Also, there are a variety of options to include properties. + +Build and Install +================= + +This extension only supported openGuass 1.0.1. + +You can also keep up with the latest fixes and features cloning the Git repository. + +``` +$ git clone https://gitee.com/enmotech/wal2json +``` + +Unix based Operating Systems +---------------------------- + +Before installing **wal2json**, you should have openGuass 1.0.1 installed(https://opengauss.org). + +If you compile PostgreSQL by yourself and install it in `/home/euler/pg13`: + +``` +$ tar -zxf wal2json-wal2json_2_3.tar.gz +$ cd wal2json-wal2json_2_3 +$ export PATH=/home/omm/openGuass/bin:$PATH +$ make +$ make install +``` + +Configuration +============= + +postgresql.conf +--------------- + +You need to set up at least two parameters at postgresql.conf: + +``` +wal_level = logical +# +# these parameters only need to set in versions 9.4, 9.5 and 9.6 +# default values are ok in version 10 or later +# +max_replication_slots = 10 +max_wal_senders = 10 +``` + +After changing these parameters, a restart is needed. + +Parameters +---------- + +* `include-xids`: add _xid_ to each changeset. Default is _false_. +* `include-timestamp`: add _timestamp_ to each changeset. Default is _false_. +* `include-schemas`: add _schema_ to each change. Default is _true_. +* `include-types`: add _type_ to each change. Default is _true_. +* `include-typmod`: add modifier to types that have it (eg. varchar(20) instead of varchar). Default is _true_. +* `include-type-oids`: add type oids. Default is _false_. +* `include-domain-data-type`: replace domain name with the underlying data type. Default is _false_. +* `include-column-positions`: add column position (_pg_attribute.attnum_). Default is _false_. +* `include-not-null`: add _not null_ information as _columnoptionals_. Default is _false_. +* `include-default`: add default expression. Default is _false_. +* `include-pk`: add _primary key_ information as _pk_. Column name and data type is included. Default is _false_. +* `pretty-print`: add spaces and indentation to JSON structures. Default is _false_. +* `write-in-chunks`: write after every change instead of every changeset. Default is _false_. +* `include-lsn`: add _nextlsn_ to each changeset. Default is _false_. +* `include-unchanged-toast` (deprecated): Don't use it. It is deprecated. +* `filter-origins`: exclude changes from the specified origins. Default is empty which means that no origin will be filtered. It is a comma separated value. +* `filter-tables`: exclude rows from the specified tables. Default is empty which means that no table will be filtered. It is a comma separated value. The tables should be schema-qualified. `*.foo` means table foo in all schemas and `bar.*` means all tables in schema bar. Special characters (space, single quote, comma, period, asterisk) must be escaped with backslash. Schema and table are case-sensitive. Table `"public"."Foo bar"` should be specified as `public.Foo\ bar`. +* `add-tables`: include only rows from the specified tables. Default is all tables from all schemas. It has the same rules from `filter-tables`. +* `filter-msg-prefixes`: exclude messages if prefix is in the list. Default is empty which means that no message will be filtered. It is a comma separated value. +* `add-msg-prefixes`: include only messages if prefix is in the list. Default is all prefixes. It is a comma separated value. `wal2json` applies `filter-msg-prefixes` before this parameter. +* `format-version`: defines which format to use. Default is _1_. +* `actions`: define which operations will be sent. Default is all actions (insert, update, delete, and truncate). However, if you are using `format-version` 1, truncate is not enabled (backward compatibility). + +Examples +======== + +There are two ways to obtain the changes (JSON objects) from **wal2json** plugin: calling functions via SQL or pg_recvlogical. + +pg_recvlogical +-------------- + +Besides the configuration above, it is necessary to configure a replication connection to use pg_recvlogical. A logical replication connection in version 9.4, 9.5, and 9.6 requires `replication` keyword in the database column. Since version 10, logical replication matches a normal entry with a database name or keywords such as `all`. + +First, add a replication connection rule at pg_hba.conf (9.4, 9.5, and 9.6): + +``` +local replication myuser trust +``` + +If you are using version 10 or later: + +``` +local mydatabase myuser trust +``` + +Also, set max_wal_senders at postgresql.conf: + +``` +max_wal_senders = 1 +``` + +A restart is necessary if you changed max_wal_senders. + +You are ready to try **wal2json**.
