Fooling around with MySQL JSON full-text indexing
Employee +1 Vote Up -0Vote Down

MySQL 5.7/8.0 does not allow creating a full-text index on a JSON column. Although a full-text index would be useful – unstructured data deserves unstructured search. I am unaware o any workaround of this limitation that does not require storing the JSON data twice. Then I started messing around, allowed indexing of JSON columns, saw great execution times but eventually followed MySQLs’ decision to call it a day. Friday afternoon rambling on indexing and easy hacking…

Why full-text: JSON indexing limitations and …

MySQL Document Store: unstructured data, unstructured search
Employee +2 Vote Up -0Vote Down

Storing documents is convenient: no need to define a schema up-front, no downtime for schema changes, no normalization, no slow joins – true or not, you name it. But what about search if you do not know how your data is structured? For example, the famous SFW-construct requires listing the columns to search: SELECT … FROM … WHERE some_column = ‘Jippie’ . Given that JSON data can have no schema how to write a query without knowing any field names, where is SELECT … FROM … WHERE * = ‘Jippie’? JSON_SEARCH() gets …

Use the index, JSON! Aggregation performance (Elastic, MySQL, MongoDB)
Employee +0 Vote Up -0Vote Down

Use the index, Luke!? No: use the index, JSON! When hunting features the X DevAPI should consider I got shocked by some JSON query execution times. Sometimes the MySQL Document Store runs head-on-head with MongoDB, sometimes not. Sometimes the difference to …

Aggregation features, Elasticsearch vs. MySQL (vs. MongoDB)
Employee +0 Vote Up -0Vote Down

To make the MySQL Document Store primary programming interface, the X DevAPI, a success we should provide building blocks to solve common web development tasks, for example, faceted search. But is there any chance a relational database bend towards a document store can compete around aggregation …

Faceted search, why the DevAPI could matter one day
Employee +0 Vote Up -0Vote Down

Faceted search or faceted navigation is a highly praised and widely use search pattern. And, it is a great reply to an off the records sales engineering question. MySQL finally has some document store features built-in. A bit of a yawn in 2016. There is a new X DevAPI available with some Connectors. …

PECL/mysqlnd_ms needs updates for MySQL Group Replication
Employee +2 Vote Up -0Vote Down

‘Synchronous’, multi-master, auto-everything – that’s the new MySQL Group Replication (IPC14 talk/slides) in simple words. After torturing PHP developers for decades with MySQL Replication there is now a new replication option which does not require read-write splitting. A system that does not know about slave lags and reading stale data. In theory, MySQL Group Replication is just about the perfect approach to run a standard PHP application (WordPress, Drupal, …) on a small cluster (3-7 nodes) in LAN settings. In theory, MySQL Group Replication …

Is the HTTP Plugin for MySQL secure?
Employee +1 Vote Up -0Vote Down

The HTTP Plugin for MySQL offers three APIs: REST-like CRUD, REST-like JSON DOCUMENT and SQL. The SQL API lets you run any SQL you want. Including, for example, DROP mysql.users if you mess up your setup. Insecure? It depends on your viewpoint.

It’s more than just another protocol…

On the first look HTTP is just another network protocol for sending requests to MySQL. HTTP is the protocol of the web. Whether you need to integrate MySQL in a larger setup and use web services for data exchange or you want to access MySQL from a JavaScript client …

MySQL 5.7 – HTTP Plugin for MySQL
Employee +3 Vote Up -0Vote Down

It is official: MySQL listens to HTTP and speaks JSON. MySQL got a new plugin that lets HTTP clients and JavaScript users connect to MySQL using HTTP. The development preview brings three APIs: key-document for nested JSON documents, CRUD for JSON mapped SQL tables and plain SQL with JSON replies. More so: MySQL 5.7.4 has SQL functions for modifying JSON, for searching documents and new indexing methods! The download and documentation (also here) is on http://labs.mysql.com/, the slides are below:

PECL/mysqlnd_ms: summer time, (connection) pool time – Fabric support internals
Employee +0 Vote Up -0Vote Down

The MySQL replication and load balancing plugin for PHP, PECL/mysqlnd_ms, aims to make using a cluster of MySQL servers instead of a single server as transparent as possible. Should you ever want to migrate your PHP app from a single MySQL server to any kind of MySQL cluster, install PECL/mysqlnd_ms and see how much breaks. A simple app, might need no code changes at all. Your APIs connect call remains unchanged, your query execution calls remain the same: one connection handle transparently …

PECL/mysqlnd_ms: how failed XA transactions get fixed
Employee +0 Vote Up -0Vote Down

XA transactions are an open standard for distributed transactions. A distributed or global transaction can spawn multiple databases. XA transactions come handy, for example, when data sets are sharded over multiple servers and a business transaction affects multiple shards. The free MySQL Fabric tools help to setup and manage a sharded MySQL cluster. The development version of …
