-----------------------------------------------------------------
[~ibessonov] suggested to try the following quick fix:
Let's make the following call synchronous, and check if this will help:
At org.apache.ignite.internal.table.distributed.TableManager#tableAsyncInternal:
{code:java}
return orStopManagerFuture(schemaSyncService.waitForMetadataCompleteness(now))
.thenComposeAsync(unused -> inBusyLockAsync(busyLock, () ->
{
...
{code}
Replace this with:
{code:java}
if (fut.isDone()) ...
{code}

>
> Performance difference between embedded and client modes is affected
> considerably by the call to *IgniteTablesInternal#tableAsync(int id)*. This
> call has to be performed on every individual table operation.
> We should make it as fast as possible. Something like a dictionary lookup +
> quick check for deleted table.
