SnappyData Provisioning Options

Prerequisites

Before you start the installation, make sure that Java SE Development Kit 8 is installed, and the JAVA_HOME environment variable is set on each computer.

The following options are available for provisioning SnappyData:

Configuring the Limit for Open Files and Threads/Processes

On a Linux system, you can set the limit of open files and thread processes in the /etc/security/limits.conf file.
A minimum of 8192 is recommended for open file descriptors limit and >128K is recommended for the number of active threads.
A typical configuration used for SnappyData servers and leads can appear as follows:

snappydata          hard    nofile      32768
snappydata          soft    nofile      32768
snappydata          hard    nproc       unlimited
snappydata          soft    nproc       524288
snappydata          hard    sigpending  unlimited
snappydata          soft    sigpending  524288
  • snappydata is the user running SnappyData.

Recent linux distributions using systemd (like RHEL/CentOS 7, Ubuntu 18.04) require the NOFILE limit to be increased in systemd configuration too. Edit /etc/systemd/system.conf as root, search for #DefaultLimitNOFILE under the [Manager] section. Uncomment and change it to DefaultLimitNOFILE=32768. Reboot for the above changes to be applied. Confirm that the new limits have been applied in a terminal/ssh window with "ulimit -a -S" (soft limits) and "ulimit -a -H" (hard limits).
