When you need to set value to "UV_THREADPOOL_SIZE"?

• Libuv has a default thread pool size of 4, and uses a queue to manage access to the thread pool - the upshot is that if you have 5 long-running DB queries all going at the same time, one of them (and any other asynchronous action that relies on the thread pool) will be waiting for those queries to finish before they even get started.

• Note, however, that tuning UV_THREADPOOL_SIZE may make more sense for a standalone application like a CLI written in Node.js. If you are standing up a bunch of Node.js processes using the cluster module then I would be surprised if tuning UV_THREADPOOL_SIZE was particularly beneficial for you. But if your application resembles the web tooling benchmarks then tuning UV_THREADPOOL_SIZE may help with performance.

Avro serialization

There are 4 possible serialization format when using avro:

• Avro Json encoding
• Avro Data Serialization (https://avro.apache.org/docs/current/spec.html#Data+Serialization) Binary format with an header that contains the full schema, this is the format usually used when writing Avro files
• Avro Single Object Encoding (https://avro.apache.org/docs/current/spec.html#single_object_encoding) Binary format with an header with only the fingerprint/id of the schema, this it the format used by Kafka (see this
• Avro Binary Encoding (https://avro.apache.org/docs/current/spec.html#binary_encoding)

Recientemente StarUML se actualizó de 2.0 a 3.0. El método de crack original, la forma de modificar la función de verificación de licencia no se puede usar. La ubicación de instalación ha cambiado y se ha encontrado el archivo LicenseManagerDomain.js. ¿Qué debería hacer? El viejo conductor les dijo a todos que resolvieran el problema.

StarUML está escrito en nodejs. Específicamente, está escrito en el marco frontal de Electron. Todo el código fuente de starUML en la nueva versión viene empaquetado por la herramienta asar.

How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/
