PostgreSQL で簡易に MQ - 木曜不足
「PostgreSQL で安くて早くてうまい MQ 作ってね」的ミッションがどこからともなく降ってきたので、色々調べて試してみたところ、案外よい方法が見つかったので、まとめてみた。 [4/24] 複数キューを扱う場合の方法を tableoid を利用するように更新。 [4/27] フィルタ条件を付ける場合の記法について追記(WHERE 句内の評価順の明示的指定) [4/30] 優先順位に ORDER BY は利用できない旨追記 鍵は advisory lock。PostgreSQL 8.2 以降の機能だ。 メッセージキューと言っても、安くて早いわけだからもちろんフルフルの高機能なわけなく、いろいろ制限がある。 receiver は複数可。メッセージは receiver の一つが受信する。ブロードキャスト/マルチキャストは対象外。 ack あり。ack せずに receiver が落ちた場合

py-amqplib Python client for the Advanced Message Queuing Procotol (AMQP) Now on GitHub Implements a simple non-threaded client library for AMQP 0-8, tested with RabbitMQ. I was looking for something that could be used in an embedded Python environment (py-exim-localscan), in which case reliance on threading would probably cause trouble. A quick connection time was desirable too. QPID takes a whil
