legacy-encoding - Support as many legacy encodings as possible

  •    Javascript

This function takes a plain text string (the input parameter) and encodes it acording the encoding. The return value is a Buffer. The optional options object and its mode property can be used to set the error mode. For encoding, the error mode can be 'fatal' (the default) or 'html'.

postcss-logical - Use logical properties and flow-relative values in CSS

  •    CSS

PostCSS Logical Properties and Values lets you use logical, rather than physical, direction and dimension mappings in CSS, following the CSS Logical Properties and Values specification. Otherwise, consider using the dir option to transform all logical properties and values to a specific direction.

lapidus - Stream your PostgreSQL, MySQL or MongoDB databases anywhere, fast.

  •    Javascript

Currently MySQL and PostgreSQL databases are fully supported. MongoDB supports inserts and deletes, however, updates return a copy of the operation (for example, a $rename operation will return a $set for the new field and an $unset for the old field) instead of the object as it exists in the database. Redis support is on the way. Lapidus can currently be used as a daemon or Node.js module. Support for piping line-delimited JSON to other processes is a high priority. You'll need PostgreSQL 9.4 or higher with logical replication configured and the JSONCDC plugin installed and loaded. Any PostgreSQL fork that ships with pg_recvlogical should be compatible.




helf

  •    Haskell

A Haskell implementation of the Edinburgh Logical Framework. helf parses and typechecks .elf files written for the Twelf implementation of the Logical Framework. helf is mainly a laboratory to experiment with different representation of lambda-terms for bidirectional typechecking.

pg_shardman - PostgreSQL sharding built on partitioning, postgres_fdw and logical replication

  •    Python

pg_shardman is a PG 11 experimental extenstion which explores applicability of Postgres partitioning, postgres_fdw and logical replication for sharding. It allows to hash-shard tables using pg_pathman and move the shards across nodes, balancing read/write load. You can issue queries to any node, postgres_fdw is responsible for redirecting them to the proper one. To avoid data loss, we support replication of partitions via synchronous or asynchronous logical replication (LR), redundancy level is configurable. Manual failover is provided. While pg_shardman can be used with vanilla PostgreSQL 11, some features require patched core. Most importantly, to support sane cross-node transactions, we use patched postgres_fdw with 2PC for atomicity and distributed snapshot manager providing snapshot isolation level of xact isolation. We support current version here, which we call 'patched Postgres' in this document. To manage the cluster, we need one designated PG node which we call shardlord. This node accepts sharding commands (implemented as usual PG functions) from the user and makes sure the whole cluster changes its state as desired. Shardlord holds several tables (see below) forming cluster metadata -- which nodes are in cluster and which partitions they keep. Currently shardlord can't keep sharded data itself and is manually configured by the administrator. We will refer to the rest of the nodes as worker nodes or workers.

psql-streamer - Stream database events from PostgreSQL to Kafka

  •    Go

This service receives the database events from PostgreSQL using logical replication protocol and feeds them to sinks based on the configuration file settings. Also can receive the events from Kafka generated by e.g. another psql-streamer instance. Receive database events from PostgreSQL using logical replication protocol and transform them into a common event format.
