Sequins is a key/value database for serving static batch data.
It's well-suited to making data generated by Hadoop available to processes that need low-latency, reliable access.
It's designed to be:
- Horizontally scalable: replicate a hot dataset over a few nodes, or partition a large one over many.
- Reliable: serve your data without an online dependency on Hadoop or HDFS. Sequins is built to be resilient to multi-node failures.
- Interoperable: load data from HDFS or S3 in Hadoop's SequenceFile format. Tools like Spark or Impala can also be used to generate data.
- Accessible: fetch values with HTTP GET; no client library required.
