![]() Zstd is a compression library that Facebook developed. Zstandard Compression or zstd, another newer block compression method provided by MongoDB starting for v4.2, provides higher compression rates. A streamable format that allows for quick processing.Fast compression and decompression speeds.Snappy is a compression library developed by Google.īenefits of snappy compression in MongoDB: Snappy compression is designed to be fast and efficient regarding memory usage, making it a good fit for MongoDB workloads. ![]() Block compression can improve performance by allowing data to be read and written in smaller chunks.īy default, MongoDB provides a snappy block compression method for storage and network communication. When this data block is read, it decompresses it in memory and presents it to the incoming request.īlock compression is a type of compression that compresses data in blocks rather than compressing the entire data set at once. When data is written to disk, MongoDB compresses it with a specified block compression method and then writes it to disk. ![]() MongoDB offers various block compression methods used by the WiredTiger storage engine, like snappy, zlib, and zstd. Percona Server for MongoDB (PSMDB) supports all types of compression and enterprise-grade features for free. ![]() We will discuss snappy and zstd for data block and zstd compression in a network. In this blog, we will discuss both data and network-level compression offered in MongoDB. As the amount of data grows, the need for efficient data compression becomes increasingly important to save storage space, reduce I/O overhead, and improve query performance. Storage reduction alone results in significant cost savings, and we can save more data in the same space. Compression in any database is necessary as it has many advantages, like storage reduction, data transmission time, etc. ![]()
