You must use post when the identity information of the created resource is exactly what is available only to the server. Es points of note when creating index libraries and indexes ? 1) The index library name must be all lowercase, cannot begin with an underscore, and cannot cont

First, download ES I'm using the 6.2.2 version here. The download address is as follows: Https://www.elastic.co/products/elasticsearch Second, decompression: Tar zxvf elasticsearch-6.2.2.tar.gz Get elasticsearch-6.2.2 folder after successful decompression Third, create ES users The default ES 6.x.x does not allow the root user to run, otherwise

Basic concepts:Indexed indexES bar data is placed in one or more indexes, and if compared with a relational database model, the index is equivalent to the database instance (DB). The base unit for index storage and reading is the document. ES is used internally to read and write data in the index that Apache Lucene implements. (es is considered a separate index, more than one in Lucene, because in distribut

Key Concepts: ES: es--elementary Streams (Raw stream) is a data stream that comes directly from the encoder, which can be an encoded video data stream (H.264,mjpeg, etc.), an audio data stream (AAC), or other encoded data stream collectively. After the ES stream passes through the PES packager, it is converted into a PES package.

Label:Elasticsearch is now the technology frontier Big Data Engine, the common combination has Es+logstash+kibana as a set of mature log system, in which Logstash is the ETL tool, Kibana is the data analysis display platform. Es Amazing is his strong search-related capabilities and disaster preparedness Strategy, ES open up a number of interfaces for developers t

Core tip: Background introduction opensl ES is a hardware audio acceleration API specifically optimized for embedded systems, with no licensing fees and can be used across platforms. It provides a high-performance, standardized, low-latency feature implementation that provides standards for embedded media development, and embedded developers are also making it easier to develop native audio applications that enable the use of the API for software/hard

However, this has gone through some time--nearly 10 years of standardization work.But the waiting is nearing the end.

The previous articles show how to capture audio using the Audiorecord provided by Android in the Java layer, play audio with audiotrack, and encode and decode using MEDIACODEC, which are Java layer APIs provided by Android , whether it is acquisition, playback, or codec, these API interfaces need to copy audio data from Java to the native layer, or from the native layer to Java, if you want to reduce the copy and develop more efficient Android audio applications, it is recommended to use the And

Android currently supports several versions of the OpenGL ES API: OpenGL ES 1.0 and 1.1:android 1.0 and later versions support this API specification. OpenGL ES 2.0:android 2.2 (API 8) and later versions support this API specification. OpenGL ES 3.0:android 4.3 (API 18) and later versions support this

This article is the seventh article in my "Android Audio development" series, the previous article generally describes the basic overview of the Android OpenSL ES API, which tells you what the framework has, what you can do, and what you can't do. This article focuses on some of the key design and concepts of the OPENSL ES framework and its API interfaces, so that you can better read the relevant code for O

Projection The 2D plotting of OpenGL ES is mapped to the screen through "projection. We have already mentioned that OpenGL ES is mainly related to triangles. A triangle has three vertices in 3D space (remember that OpenGL ES performs operations on graphics in 3D space ). To draw such a triangle in framebuffer, OpenGL ES
