7.1.1

7.1.0

Features

  • Added USE_GRV_CACHE transaction option to allow read versions to be locally cached on the client side for latency optimizations. (PR #5725) (PR #6664)
  • Added “get range and flat map” feature with new APIs (see Bindings section). Storage servers are able to generate the keys in the queries based on another query. With this, upper layer can push some computations down to FDB, to improve latency and bandwidth when read. (PR #5609), (PR #6181), etc..

Performance

Reliability

Fixes

Status

  • Added cluster.storage_wiggler field report storage wiggle stats (PR #6219)

Bindings

  • C: Added fdb_transaction_get_range_and_flat_map function to support running queries based on another query in one request. (PR #5609)
  • Java: Added Transaction.getRangeAndFlatMap function to support running queries based on another query in one request. (PR #5609)

Other Changes

  • Change perpetual storage wiggle to wiggle the storage servers based on their created time. (PR #6219)
