aerospike-client-go v2.0.0 Release Notes

Release Date: 2019-03-19 // about 5 years ago

  • Major release. There are some breaking changes, both syntactically and semantically. Most changes are minor, and can be fixed with relative ease. The only major issue is that the behavior of the client when a key does not exist has changed. It used to return no error, but nil Record.Bins. Now it returns ErrKeyNotFound error. This is a significant changes, and you should search your code for all instances of Bins == nil and adapt the code accordingly.

    • Major:

      • Optimizes connection creation out of the transaction pipeline and makes it async.
      • Put a threshold on the number of connections allowed to open simultaneously. Controlled via ClientPolicy.OpeningConnectionThreshold.
      • Do not clear partition map entry when a node reports that it no longer owns that partition entry.
      • Uses rolling timeout instead of strict timeout for connections.
      • Remove ToValueArray and ToValueSlice methods to discourage such suboptimal use. Changes QueryAggregate signature to remove the need for those methods.
      • Remove unnecessary conversion from BinMap to Bins in reflection API to speedup the command an avoid unnecessary memory allocations.
      • Use shorter intervals with exponential back-off for tasks.

    • Breaking:

      • Get/Put/Touch/Operate and ExecuteUDF commands will return an ErrKeyNotFound error when the key does not exist in the database. The old behavior used to be not to return an error, but have an empty Record.Bins.
      • Renames Statement.Addfilter to Statement.SetFilter, change the name and type of Statement.Filters to Statement.Filter.
      • Remove ClientPolicy.RequestProleReplicas. THe client will always request them.
      • Removes ScanPolicy.ServerSocketTimeout and QueryPolicy.ServerSocketTimeout in favor of the already existing Policy.SocketTimeout.
      • Renames Policy.Timeout to Policy.TotalTimeout to make the naming consistent with other clients.
      • Moves atomic package to internal.
      • Moves ParticleType package to internal.
      • Moves RequestNodeInfo and RequestNodeStats to methods on Node object, and adds InfoPolicy to the relevant API signatures.
      • Removes WaitUntilMigrationIsFinished from Scan/Query policies.
      • Changes NewConnection method signature, makes LoginCommand private.
      • Makes OperationType private.
      • Remove long deprecated method for pool management.
      • Removes unused ReadN method in Connection.
      • Embeds Policies as values and not pointers inside MultiPolicy, ScanPolicy, QueryPolicy

    • Minor:

      • Fixes a race condition in the AdminCommand.
      • Synchronize the XORShift to avoid race conditions.
      • Completely removes deprecated LDT code.
