What Is a Slot?

A slot is a narrow opening, groove, or slit. The word is used in many contexts, including:

In casinos, a slot is an area on a game machine where coins or paper tickets are inserted for play. Some slot machines are equipped with a barcode reader that allows players to scan their tickets or loyalty cards to play. Other machines require players to place a paper ticket into a slot or an electronic chip tray to start the game.

Slots and table games coexist in casinos, each with its own distinct appeal. However, there is little agreement on the relative contribution of each to casino revenue. A recent Eadington Fellows Project by Grant Stousland aims to shed light on this issue.

The study involves analyzing data from multiple properties and collecting player surveys to measure the impact of hold on average time on device. The research will also explore whether the amount of hold degrades the experience for players.

While there is a lot of variation in hold among different casinos and games, there are some general trends that seem to be associated with the amount of hold:

For example, higher hold tends to decrease total play, and lower hold increases it. In addition, higher hold typically leads to better performance on the floor, while lower hold generally does not. This suggests that a casino should adjust its hold strategy based on a number of factors:

A slot is a location in an optical library, defined by the combination of NAME and OLIBRARY. A slot is represented by a row in the SLOT table (table space OCSLTTSP). The slot table holds one row for each optical library cartridge slot. Each slot is represented by a unique pathname, which can be an absolute or relative pathname. The slot table is created during the initialization of the OCSLTTSP library.

The number of slots available to a job depends on the size of the dataset and the number of jobs running in BigQuery simultaneously. By default, load and extract jobs share access to a free pool of slots. If this pool is full, your job might wait for a slot to become available. Dedicated slots enable your jobs to use more capacity and improve query performance. You can purchase dedicated slots by creating a reservation and assigning PIPELINE jobs to it.

You can only buy a maximum of a certain number of slots per location at a time. The number of slots you can purchase is displayed next to the Slots menu in the BigQuery UI. You can also see the number of committed slots that you own in the Slots tab of the admin project in BigQuery. The administration project is billed for the committed slots that it uses, and projects that share these slots with the administration project are not billed.
