This is the first major breaking release of the Go client in 5 years.
Most breaking changes are minor and specific, and will either not hit you, or will be fixable with relative ease.
The only major change is that the behavior of the client when a key does not exist has changed.
It used to return no errors, but anil
Record.Bins
. Now it returnsErrKeyNotFound
error.
This is a significant change, and you should search your code for all instances of.Bins == nil
(or equivalent) and adapt the code accordingly.
-
Major Changes And Improvements:
- Optimizes connection creation out of the transaction pipeline and makes it async.
- Puts 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. This means that every time a connection is read, the timeout is set to
policy.SocketTimeout
again, unless it will take longer than the whole transactionTotalTimeout
. - Remove
ToValueArray
andToValueSlice
methods to discourage such sub-optimal use. ChangesQueryAggregate
signature to remove the need for those methods. - Remove unnecessary conversion from
BinMap
toBin
s in reflection API to speed up the command and avoid unnecessary memory allocations. - Use shorter intervals with exponential back-off for tasks.
-
Breaking Changes:
Get
/Put
/Touch
/Operate
andExecuteUDF
commands will return anErrKeyNotFound
error when the key does not exist in the database. The old behavior used to be not to return an error, but have an emptyRecord.Bins
.- Renames
Statement.Addfilter
toStatement.SetFilter
, changes the name and type ofStatement.Filters
toStatement.Filter
. - Remove
ClientPolicy.RequestProleReplicas
. The client will always request them. - Removes
ScanPolicy.ServerSocketTimeout
andQueryPolicy.ServerSocketTimeout
in favor of the already existingPolicy.SocketTimeout
. - Renames
Policy.Timeout
toPolicy.TotalTimeout
to make the naming consistent with other clients. - Moves
atomic
package to internal. - Moves
ParticleType
package to internal. - Moves
RequestNodeInfo
andRequestNodeStats
to methods on Node object, and addsInfoPolicy
to the relevant API signatures. - Removes
WaitUntilMigrationIsFinished
fromScan
/Query
policies. - Changes
NewConnection
method signature - Makes
LoginCommand
private. - Makes
OperationType
private. - Remove long deprecated method for pool management.
- Removes unused
ReadN
method inConnection
. - Embeds Policies as values and not pointers inside
MultiPolicy
,ScanPolicy
,QueryPolicy
-
Minor Improvements and Fixes:
- Fixes a race condition in the
AdminCommand
. - Synchronize the
XORShift
to avoid race conditions. - Completely removes deprecated LDT code.
