Bigtable is a fully managed wide-column and key-value NoSQL database service for large analytical and operational workloads as part of the Google Cloud portfolio.
[7] Google's reasons for developing its own database include scalability and better control of performance characteristics.
[10] On January 27, 2022, Google announced a number of updates to Bigtable, including automated scalability.
When Table size threaten to grow beyond a specified limit, the tablets may be compressed using the algorithm BMDiff[13][14] and the Zippy compression algorithm[15] publicly known and open-sourced as Snappy,[16] which is a less space-optimal variation of LZ77 but more efficient in terms of computing time.
Like GFS's master server, the META0 server is not generally a bottleneck since the processor time and bandwidth necessary to discover and transmit META1 locations is minimal and clients aggressively cache locations to minimize queries.
