The configuration for using lettuce in our service is as follows: ClusterClientOptions clientOptions = ClusterClientOptions.builder() .timeoutOptions(TimeoutOptions.enabled(Duration.ofMillis(1000))) .autoReconnect(true) .maxRedirects(3) .pingBeforeActivateConnection(false) .disconnectedBehavior(ClientOptions.DisconnectedBehavior.REJECT_COMMANDS) .socketOptions(socketOptions) .topologyRefreshOptions(clusterTopologyRefreshOptions) .cancelCommandsOnReconnectFailure(false) .protocolVersion(ProtocolVersion.RESP2) .build();

The following error information is displayed during service running: java.util.concurrent.CompletionException: io.lettuce.core.RedisCommandTimeoutException: Command timed out after 1 second(s) at java.util.concurrent.CompletableFuture.encodeThrowable(CompletableFuture.java:292) at java.util.concurrent.CompletableFuture.completeThrowable(CompletableFuture.java:308) at java.util.concurrent.CompletableFuture.biRelay(CompletableFuture.java:1300) at java.util.concurrent.CompletableFuture$BiRelay.tryFire(CompletableFuture.java:1284) at java.util.concurrent.CompletableFuture$CoCompletion.tryFire(CompletableFuture.java:1034) at java.util.concurrent.CompletableFuture.postComplete(CompletableFuture.java:488) at java.util.concurrent.CompletableFuture.completeExceptionally(CompletableFuture.java:1990) at io.lettuce.core.protocol.AsyncCommand.doCompleteExceptionally(AsyncCommand.java:139) at io.lettuce.core.protocol.AsyncCommand.completeExceptionally$original$yKf0WaAm(AsyncCommand.java:132) at io.lettuce.core.protocol.AsyncCommand.completeExceptionally$original$yKf0WaAm$accessor$HHhaprxn(AsyncCommand.java) at io.lettuce.core.protocol.AsyncCommand$auxiliary$TO9bajWk.call(Unknown Source) at org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstMethodsInter.intercept(InstMethodsInter.java:86) at io.lettuce.core.protocol.AsyncCommand.completeExceptionally(AsyncCommand.java) at io.lettuce.core.cluster.ClusterCommand.completeExceptionally$original$ECOE1qPZ(ClusterCommand.java:99) at io.lettuce.core.cluster.ClusterCommand.completeExceptionally$original$ECOE1qPZ$accessor$knWUXfon(ClusterCommand.java) at io.lettuce.core.cluster.ClusterCommand$auxiliary$CfagtcCY.call(Unknown Source) at org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstMethodsInter.intercept(InstMethodsInter.java:86) at io.lettuce.core.cluster.ClusterCommand.completeExceptionally(ClusterCommand.java) at io.lettuce.core.protocol.CommandExpiryWriter.lambda$potentiallyExpire$0(CommandExpiryWriter.java:175) at io.netty.util.concurrent.PromiseTask.runTask(PromiseTask.java:98) at io.netty.util.concurrent.ScheduledFutureTask.run(ScheduledFutureTask.java:153) at io.netty.util.concurrent.AbstractEventExecutor.runTask(AbstractEventExecutor.java:174) at io.netty.util.concurrent.DefaultEventExecutor.run(DefaultEventExecutor.java:66) at io.netty.util.concurrent.SingleThreadEventExecutor$4.run(SingleThreadEventExecutor.java:997) at io.netty.util.internal.ThreadExecutorMap$2.run(ThreadExecutorMap.java:74) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.lang.Thread.run(Thread.java:748) Caused by: io.lettuce.core.RedisCommandTimeoutException: Command timed out after 1 second(s) at io.lettuce.core.internal.ExceptionFactory.createTimeoutException(ExceptionFactory.java:59) at io.lettuce.core.protocol.CommandExpiryWriter.lambda$potentiallyExpire$0(CommandExpiryWriter.java:176) ... 8 common frames omitted

The error logs show that the Redis command times out, but no Redis slow log is displayed in the monitoring. This problem is caused by the TimeoutOptions parameter. What is the meaning of the TimeoutOptions parameter? Is it the timeout period of the command?

Timeouts are set on a per-command basis. Once a command is dispatched (that is being invoked on the API) the timeout starts. Any preceding slow command or a blocking command can contribute that a subsequent command isn't completed.

TimeoutOptions is documented with a bit of these details. What additional information are you looking for?
