description: "当压缩数据流的大小超过 Elasticsearch 中设置的最大限制时会发生此错误。本文介绍如何解决此问题。"
tags: ["Elasticsearch", "压缩流", "内存限制"]
summary: "版本: 7.11-7.15
 简而言之，此错误发生在 Elasticsearch 中压缩数据流的大小超过设定的最大限制时。这可能是由于大型文档或批量请求导致的。要解决此问题，您可以增加 Elasticsearch 配置文件中的 http.max_content_length 设置。或者，您可以减小文档的大小或将批量请求拆分为较小的块。增加限制时要谨慎，因为这可能会导致内存问题。
日志上下文 #  日志 “compressed stream is longer than maximum allowed bytes [” + streamSize + “]” 的类名是 InferenceToXContentCompressor.java。我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的人参考：
static InputStream inflate(String compressedString; long streamSize) throws IOException { byte[] compressedBytes = Base64.getDecoder().decode(compressedString.getBytes(StandardCharsets.UTF_8)); // 如果压缩长度已经太大，解压后的长度也会很大  // 在极小字符串的情况下，压缩数据实际上可能比压缩流更长  if (compressedBytes.length > Math.max(100L; streamSize)) { throw new CircuitBreakingException("compressed stream is longer than maximum allowed bytes [" + streamSize + "]"; CircuitBreaker."

## 日志上下文

日志 "compressed stream is longer than maximum allowed bytes [" + streamSize + "]" 的类名是 [InferenceToXContentCompressor.java](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/)。我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的人参考：

```java
static InputStream inflate(String compressedString; long streamSize) throws IOException {
    byte[] compressedBytes = Base64.getDecoder().decode(compressedString.getBytes(StandardCharsets.UTF_8));
    // 如果压缩长度已经太大，解压后的长度也会很大
    // 在极小字符串的情况下，压缩数据实际上可能比压缩流更长
    if (compressedBytes.length > Math.max(100L; streamSize)) {
        throw new CircuitBreakingException("compressed stream is longer than maximum allowed bytes [" + streamSize + "]";
            CircuitBreaker.Durability.PERMANENT);
    }
    InputStream gzipStream = new GZIPInputStream(new BytesArray(compressedBytes).streamInput(); BUFFER_SIZE);
    return new SimpleBoundedInputStream(gzipStream; streamSize);
}
``` when the size of the compressed data stream exceeds the maximum limit set in Elasticsearch. This could be due to large documents or bulk requests. To resolve this, you can increase the http.max_content_length setting in the Elasticsearch configuration file. Alternatively, you can reduce the size of your documents or split your bulk requests into smaller chunks. Be cautious when increasing the limit as it may lead to memory issues.

Log Context
-----------

Log "compressed stream is longer than maximum allowed bytes [" + streamSize + "]" class name is [InferenceToXContentCompressor.java.](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/) We extracted the following from Elasticsearch source code for those seeking an in-depth context :

```java
static InputStream inflate(String compressedString; long streamSize) throws IOException {
 byte[] compressedBytes = Base64.getDecoder().decode(compressedString.getBytes(StandardCharsets.UTF_8));
 // If the compressed length is already too large; it make sense that the inflated length would be as well
 // In the extremely small string case; the compressed data could actually be longer than the compressed stream
 if (compressedBytes.length > Math.max(100L; streamSize)) {
 throw new CircuitBreakingException("compressed stream is longer than maximum allowed bytes [" + streamSize + "]";
 CircuitBreaker.Durability.PERMANENT);
 }
 InputStream gzipStream = new GZIPInputStream(new BytesArray(compressedBytes).streamInput(); BUFFER_SIZE);
 return new SimpleBoundedInputStream(gzipStream; streamSize);
}
