Re: Questions about SQL interface

Hello Slava, the workaround totally works for me, I already have an Interceptor for certain caches anyway. Thanks a lot for looking into this. Will you take care of the jira ticket, too? Cheers Wolfram On 23/01/2018 06:19, slava.koptilin wrote: Hello, Here is the SQL statement and the exc

Reconnect after cluster shutdown fails

Hello together, I have one client and one server, it's no problem to kill the client and restart it, it always has access to the server's cache after the restart is finished. When I stop the server (to simulate a full cluster shutdown) and restart it after waiting for a couple of seconds the

Re: PHP and Apache Ignite - very slow query

Hi! If you don't run both queries from PHP, you cannot really compare the results. Running queries from the mysql console means that you don't have to establish a connection, which takes quite some time. You don't have to use ODBC to connect to MySQL, PDO will do a fine job and makes your da

Hello Alexey, thanks for looking into this. It's rather odd this only happens with the PHP Redis client, but for me it doesn't matter. I will either use a Memcached implementation in front of a client or a Spring based HTTP API on the server nodes to connect other languages. If you need anyt

Memcached doesn't store flags

Hello together, Ignite's current Memcached implementation doesn't store the flags value which comes with the set command. As Memcached can only store strings, memcached clients usually use this as a workaround to store the datatype and later restore the string from memcached to the original da
