Fast and Economical

Episilia costs less because it is fast

Zero Bottlenecks
Zero Bottlenecks (2).png
  • Peer to Peer collaborative architecture; no SPOF

  • Stateless components to scale horizontally

  • No central database; S3 is the primary datastore for logs

  • Indexer and search instances scale independent of each other 

Minimal Data Footprint.png
Minimal Data Footprint
  • Data structures exploit natural order and repeatable values in logs 

  • Double optimized bloom filters with index size at 1.5% of log bytes

  • Logs and index LZ4 compressed. 10TB of logs zips to 1TB on disk

  • Flatbuffer format to de-serialize data with less cpu cycles 

CPU and RAM Optimized.png
CPU and RAM Optimized
  • C++ with SIMD indexes logs at 10-20MBps/core or 1TB/core/day

  • 10 concurrent search queries with just 4 Cores + 4GB RAM

  • 3 Tier cache in RAM, Rocksdb and Local FS

  • Tail has a guaranteed latency of 3-5 seconds from log write to display

"We did pre-mature optimization in every step in building Episilia, for each cpu cycle and each byte."
